Spark-Csv Write quotemode not working | <p>I am trying to write a DataFrame as a CSV file using Spark-CSV (<a href="https://github.com/databricks/spark-csv" rel="noreferrer">https://github.com/databricks/spark-csv</a>)</p>
<p>I am using the command below</p>
<pre><code>res1.write.option("quoteMode", "NONE").format("com.databricks.spark.csv").save("File")
</code></pre>
<p>But my CSV file is always written as</p>
<p>"London"<br>
"Copenhagen"<br>

Click event doesnt work in safari mobile for some HTML content | <p>In my web app, there is a separate navbar for mobile devices. I want this navbar to collapse when the menu button is clicked or anywhere else in the site is clicked. It already works in any mobile browser but not it safari mobile (In safari also, for home page it works but not in other pages). In other pages, there are some html generated dynamically. It seems that the click event doesn't work for those content. I'd really appreciate a solution for this problem. the code is as follows. I've tried 'body', $(document), window instead of $('html'). It doesn't for them also.</p>
<pre><code>$('html').click(function(event) {
var clickover = $(event.target);
var $navbar = $(".navbar-collapse");
var _opened = $navbar.hasClass("in");
if (_opened === true && !clickover.hasClass("navbar-toggle")) {
$navbar.collapse('hide');
}
});
</code></pre>
<p>I've also tried what is mentioned in <a href="http://www.danwellman.co.uk/fixing-jquery-click-events-for-the-ipad/" rel="nofollow">Fixing jQuery Click Events for the iPad</a>. But the code mentioned in there doesn't trigger at all. The code I've tried for this as belows.</p>
<pre><code>var ua = navigator.userAgent,
event = (ua.match(/iPad/i)) ? "touchstart" : "click";
$('body').bind(event, function(e) {
var clickover = $(event.target);
var $navbar = $(".navbar-collapse");
var _opened = $navbar.hasClass("in");
if (_opened === true && !clickover.hasClass("navbar-toggle")) {
$navbar.collapse('hide');
}

<p>I'd really appreciate an answer for my question (I was working on this for more than a day but didn't find a solution). </p> | 0 |
How to use Spring Data / JPA to insert into a Postgres Array type column? | <p>Say I have a postgres table like so:</p>
<pre><code>CREATE TABLE sal_emp (
name text,
pay_by_quarter integer[],
schedule text[][]
);
</code></pre>
<p>Would I even be able to use Spring Data to insert into the columns <code>pay_by_quarter</code> or <code>schedule</code> ? If possible, how would this look as a Repository and Entity ? I haven't been able to find any documentation or examples addressing this, possibly because of how it overlaps with the more common use-case, inserting into multiple tables as one-to-many relations. Speaking of which, I fully intend to use the Postgresql <code>array</code> datatype and no relational tables.</p> | 0 |
R check row for row if a combination exists in another dataframe | <p>I have two data frames (df1 and df2) in R with different information except for two columns, a person number (pnr) and a drug name (name). Row for row in df1, I want to check, if the combination of pnr and name exists somewhere in df2. If this combination exists, I want "yes" in a another column in df1. If not a "no".</p>
<pre><code>df1
pnr|drug|...|check
---|----|---|-----
1 | 1 |...| no
1 | 2 |...| yes
2 | 2 |...| yes
3 | 2 |...| no
.....
df2
pnr|drug|...|
---|----|---|
1 | 2 |...|
2 | 2 |...|
....
</code></pre>
<p>For example, I want check, if the row combination pnr=1 & drug=1 exists in df2 (no), pnr=1 & drug=2 (yes) etc. And then place a "yes" or "no" in the check column in df1</p>
<p>I have tried the following <code>for</code> statement without luck. It does place a "yes or "no" in the "check" column, but it doesn't do it correctly</p>
<pre><code>for(index in 1:nrow(df1)){
if((df1[index,]$pnr %in% df2$pnr)&(df1[index,]$name %in% df2$name)){
check_text="yes"}else{check_text="no"}
df1$check=check_text
}

cannot find the declaration of element 'linearlayout' | <p>I am new to Android and learning with a book.But here comes the problem. When I decided to add a folder named layout_larger and copied the file named <code>activity_one_page_or_two.xml</code> to <code>layout_larger</code>, unfortunately I occurred the
<code>error : Error:(4, 43) cvc-elt.1.a: Cannot find the declaration of element LinearLayout</code>.No idea why it comes. Anyone could give me a hand?</p>

How to auto generate primary key ID properly with Hibernate inserting records | <p>I have a Member entity class whose primary key is defined as:</p>
<pre><code> @Id
@GeneratedValue
private Long id;
</code></pre>
<p>I pre-loaded two records into database with Hibernate when I starts the application:</p>
<pre><code>insert into Member (id, name, email, phone_number) values (0, 'John Smith', '[email protected]', '2125551212')
insert into Member (id, name, email, phone_number) values (1, 'Mary Smith', '[email protected]', '2025551212')
</code></pre>
<p>Now the MySql database has two records:</p>
<pre><code>select * from Member;
+----+---------------------------+------------+--------------+
| id | email | name | phone_number |
+----+---------------------------+------------+--------------+
| 0 | [email protected] | John Smith | 2125551212 |
| 1 | [email protected] | Mary Smith | 2025551212 |
</code></pre>
<p>+----+---------------------------+------------+--------------+</p>
<p>Now, in my member registration page, when I submit a request to register a new member, I received this error message:</p>
<pre><code>Caused by: java.sql.SQLIntegrityConstraintViolationException: Duplicate entry '1' for key 'PRIMARY'
</code></pre>
<p>I figured that it because the auto-generated key always starts with '1', but in the database, it already has two records, so the primary key '1' will be duplicate.</p>
<p>My question is, how to create the primary key properly, given a number of existing records in the table? If I don't use the </p>
<pre><code>@GeneratedValue
</code></pre>
<p>annotation, then I always have to find out what's the next key from the database table before insertion.</p>
<p>Is there a best way to handle this situation, which seems very common? </p>
<p>EDITED:
As suggested, I used the Stragey:</p>
<pre><code>@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
</code></pre>
<p>What's strange is that, if there are two existing records in the table as below:</p>
<pre><code>select * from English;
+----+------------+---------+--------+
| id | sentence | source | status |
+----+------------+---------+--------+
| 1 | i love you | unknown | 0 |
| 2 | i like you | unknown | 0 |
+----+------------+---------+--------+
</code></pre>
<p>after I register a new record into the table, the new ID starts with 4, not 3, as below. </p>
<pre><code>select * from English;
+----+----------------+---------+--------+
| id | sentence | source | status |
+----+----------------+---------+--------+
| 1 | i love you | unknown | 0 |
| 2 | i like you | unknown | 0 |
| 4 | I have a book. | Unknown | 0 |
+----+----------------+---------+--------+

JavaScript stop script if a condition is not met | <p>I have a javascript file to which I send a parameter </p>
<pre><code> <script lang="en" src="/test/load.js" ></script>
</code></pre>
<p>In the file I have script similar to this:</p>
<pre><code> ! function()
{ some code
var lag = ( script.getAttribute( 'lang' ) == null || script.getAttribute( 'lang' ) == '' ) ? exit : script.getAttribute( 'lang' );
</code></pre>
<p>The idea is that I do not want to execute the code after the one quoted above in case that parameter 'lang' is missing or is an empty string. How can I do that, I tried using</p>
<pre><code> exit
</code></pre>
<p>or</p>
<pre><code> break
</code></pre>
<p>but they do not work for me.</p> | 0 |
How do you import macros in submodules in Rust? | <p>I have the following directory structure</p>
<ul>
<li><code>/main.rs</code></li>
<li><code>/lib.rs</code></li>
<li><code>/tutorial/mod.rs</code></li>
<li><code>/tutorial/foo.rs</code></li>
</ul>
<p>In <code>foo.rs</code> I need to use a macro from the glium library, <code>implement_vertex!</code>. If I put <code>#[macro_use] extern crate glium;</code> at the head of <code>foo.rs</code>, I get a <code>error: an `extern crate` loading macros must be at the crate root</code>. I also get a <code>error: macro undefined: 'implement_vertex!'</code></p>
<p>There is also a <code>lib.rs</code> that is the crate root of the tutorial modules. I needed to put <code>#[macro_use]</code> there. Does this create 2 crate roots if I have both <code>main.rs</code> and <code>lib.rs</code>?</p>
<p>What is the correct way to import macros in a submodule?</p> | 0 |

Alternative to event.srcElement.id | <p>Currently I have a function that works perfectly for IE, Chrome and Safari in order to get the ID name of a textbox I'm placing a focus on within a Gridview.</p>
<pre><code>function onTextFocus() {
alert(event.srcElement.id);
}
</code></pre>
<p>The function is called upon during a RowDataBound for the gridview:</p>
<pre><code>protected void ItemGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
((TextBox)e.Row.FindControl("txtQuantity")).Attributes.Add("onfocus", "onTextFocus();");
}
}
</code></pre>
<p>However it doesn't work for Firefox as it doesn't recognize srcElement. So I'm looking for an alternative that would work for all browsers. After scouring Google I came up with these alternatives but I either get an undefined error or ReferenceError. Any ideas why?</p>
<pre><code>function onTextFocus() {
alert(this.id);
alert(event.currentTarget.id);
alert(event.target.id);
alert(event.currentTarget);
alert(event.target);
alert($(this).attr('id'));
alert($(obj).attr("id"));
alert($(this).id);
alert($(this).get(0).id);
alert($(this).prop("id"));

Android Constraint Layout Programmatically? | <p>In iOS I'm a big fan of deleting the storyboard and using the Cartography framework to lay everything out in code. This is stolen from Cartography's github:</p>
<pre><code>constrain(view1, view2) { view1, view2 in
view1.width == (view1.superview!.width - 50) * 0.5
view2.width == view1.width - 50
view1.height == 40
view2.height == view1.height
view1.centerX == view1.superview!.centerX
view2.centerX == view1.centerX
view1.top >= view1.superview!.top + 20
view2.top == view1.bottom + 20
}
</code></pre>
<p>Is there any equivalent at all for Android? It seems like the new Constraint Layout is a step in the right direction but I would like to do it programmatically.</p> | 0 |

Observable with Async Pipe in template is not working for single value | <p>I have a component that asks my service for an Observable object (that is, the underlying http.get returns one single object).</p>
<p>The object (an observable) is used in conjunction with an async pipe in my template.
Unfortunately, I get an error:</p>
<blockquote>
<p>Cannot read property 'lastname' of null</p>
</blockquote>
<p>I have been breaking my head on this one. A similar type of code works correctly on a list of objects (in conjunction with *ngFor).</p>
<pre class="lang-html prettyprint-override"><code><li>{{(person | async)?.lastname}}</li>
</code></pre>
<p>Method in my service:</p>
<pre class="lang-js prettyprint-override"><code>getPerson(id: string): Observable<Person> {
let url = this.personsUrl + "/" + id;
return this.http.get(url, {headers: new Headers({'Accept':'application/json'})})
.map(r => r.json())
.catch(this.handleError); //error handler
}
</code></pre>
<p>In my component:</p>
<pre class="lang-js prettyprint-override"><code>//... imports omitted
@Component({
moduleId: module.id,
selector: 'app-details-person',
templateUrl: 'details-person.component.html',
styleUrls: ['details-person.component.css'],
})
export class DetailsPersonComponent implements OnInit, OnDestroy
{
person: Observable<Person>;
sub: Subscription;
constructor(private personService: PersonService, private route: ActivatedRoute) {
}
ngOnInit() {
this.sub = this.route.params.subscribe(params => {
let persId = params['id'];
this.person = this.personService.getPerson(persId);
});
}
ngOnDestroy(): void {
this.sub.unsubscribe();
}
}
</code></pre>
<p>Apparently the observable is/returns a null object value in the pipe.
I have checked if I am really getting a nonempty Observable from my service and I can confirm that there exists an (underlying) object returned from my service.</p>
<p>Of course, I could subscribe to the observable in my component after having retrieved the Observable from the service, but I would really like to use the async construct.</p>
<p>Btw, another question: Is there already a pattern on how to handle errors that occur in the async pipe? (A downside of using async pipes.... errors are delayed until rendering time of the view.</p> | 0 |
how to use path-to-regexp to match all paths that's not starting with /api/? | <p>when using <a href="https://github.com/pillarjs/path-to-regexp" rel="noreferrer">path-to-regexp</a>, how to match all path that not starting with <code>/api/</code>?</p>
<p>By using native JavaScript RegExp <code>/^(?!\/api\/).*/</code>will match<code>/x/y/z</code>. see test result from <a href="https://regex101.com/#javascript" rel="noreferrer">here</a>
<a href="https://i.stack.imgur.com/rZe1k.png" rel="noreferrer"><img src="https://i.stack.imgur.com/rZe1k.png" alt="enter image description here"></a></p>
<p>However, it does not work with path-to-regexp. see the test result from <a href="http://forbeslindesay.github.io/express-route-tester/" rel="noreferrer">there</a></p>
<p><a href="https://i.stack.imgur.com/EvwPF.png" rel="noreferrer"><img src="https://i.stack.imgur.com/EvwPF.png" alt="enter image description here"></a></p>
<p><strong>So what's the correct way to achieve my goal in path-to-regexp?</strong></p>
<p><strong>[Update 1]</strong></p>
<p>More details:
The real case is that I'm using angular2 + koajs. And in angular2, browser may issue a client routing url to server. Please see my <a href="https://stackoverflow.com/questions/39096211/whats-the-right-way-to-set-routing-for-angular2-with-koajs">another question</a> about this.</p>
<p>To address that issue, as suggested by @mxii, I'm trying to use <a href="https://github.com/xsmallbird/koa-repath" rel="noreferrer">koa-repath</a> to redirect all requests that not started with <code>/api/</code> to the root url: <code>http://localhost:3000/</code>excepte it's static assets (js/json/html/png/...) requests.</p>
<p>And <code>koa-repath</code> use <code>path-to-regexp</code> to match the path. That's why I asked this question.</p> | 0 |
Set a connectionString for a PostgreSQL database in Entity Framework outside the app.config | <p>I have a database build with PostgreSQL, which I access through Entity Framework 6.</p>
<p>Until recently it ran smoothly through an <code>app.config</code> connectionString:</p>
<pre><code><connectionStrings>
<add
name="fancyName"
connectionString="Host=localhost; user id=allCanSee; password=notSoSecret; database=notHidden"
providerName="Npgsql" />
</connectionStrings>
</code></pre>
<p>Our lead programmer is not happy about an open connectionString, since every computer we install the software on can read it. We therefore encrypted everything, and stored the encryption in the <code>app.config</code>.</p>
<p>Now I have a new problem - I have accessed my database the following way:</p>
<pre><code>public class VersionContext
{
public virtual DbSet<DatabaseNumber> DatabaseVersion { get; set; }
public VersionContext() : base("name=fancyName")
{
System.Data.Entity.Database.SetInitializer<DatabaseContext>(null);
}
}
</code></pre>
<p>But since my <code>app.config</code> no longer contains the connectionString, I must tell the database where to look.</p>
<p>My current attempt is something like this:</p>
<pre><code>public static class VersionContextConnection
{
public static string GetConnectionString() //Accessable form everywhere
{
var providerName = "Npgsql";
var databaseName = decryptedName;
var userName = decryptedUserName;
var password = decryptedPassword;
var host = decryptedHostName
var port = 5432;
return $"Provider={providerName}; " + $"Server={host}; " + $"Port={port}; " +
$"User Id={userName}; " + $"Password={password}; " + $"Database={databaseName};";
}
}
public class VersionContext : DbContext
{
public virtual DbSet<DatabaseNumber> DatabaseVersion { get; set; }
public VersionContext() : base(VersionContextConnection.GetConnectionString())
{
System.Data.Entity.Database.SetInitializer<DatabaseContext>(null);
}
}
</code></pre>
<p>Then I'd access it as follow:</p>
<pre><code>using (var context = new VersionContext())
{
var entry = context.DatabaseVersion.FirstOrDefault();
...
}
</code></pre>
<p>But this gives an exception from <code>System.Data</code> saying <code>Keyword not supported: 'provider'.</code></p>
<p>Removing <code>provider</code> from the connectionString gives another exception: <code>Keyword not supported: 'port'.</code></p>
<p>Removing <code>port</code> from the connectionString gives a third exception from <code>.Net SqlClient Data Provider</code>: <code>Login failed for user 'secretSecret'.</code></p>
<p>So - how do I set my connectionString, if it's not set through the <code>:base(connectionString)</code> property?</p> | 0 |

Spark assign value if null to column (python) | <p>Assuming that I have the following data</p>
<pre><code>+--------------------+-----+--------------------+
| values|count| values2|
+--------------------+-----+--------------------+
| aaaaaa| 249| null|
| bbbbbb| 166| b2|
| cccccc| 1680| something|
+--------------------+-----+--------------------+
</code></pre>
<p>So if there is a null value in <code>values2</code> column how to assign the <code>values1</code> column to it? So the result should be:</p>
<pre><code>+--------------------+-----+--------------------+
| values|count| values2|
+--------------------+-----+--------------------+
| aaaaaa| 249| aaaaaa|
| bbbbbb| 166| b2|
| cccccc| 1680| something|
+--------------------+-----+--------------------+
</code></pre>
<p>I thought of something of the following but it doesnt work:</p>
<pre><code>df.na.fill({"values2":df['values']}).show()
</code></pre>
<p>I found this way to solve it but there should be something more clear forward:</p>
<pre><code>def change_null_values(a,b):
if b:
return b
else:
return a
udf_change_null = udf(change_null_values,StringType())
df.withColumn("values2",udf_change_null("values","values2")).show()

Python - Check if a string contains multiple words | <p>I'm wondering if there was a function in Python 2.7 that checks to see if a string contains multiple words (as in words with spaces/punctuation marks between them), similar to how <code>.isalpha()</code> checks to see if a string contains only letters?</p>
<p>For example, if something along the lines of this exists...</p>
<pre><code>var_1 = "Two Words"
if var_1.containsmultiplewords():
print "Yes"
</code></pre>
<p>And then "Yes" would be the output.</p>

WooCommerce action hooks and overriding templates | <p>I have started to learn how to create templates with WooCommerce and I had faced with a little problem. For instance, in the php file content-single-product.php of Woocommerce plugin I have strings like that:</p>
<pre><code> <?php
/**
* woocommerce_single_product_summary hook.
*
* @hooked woocommerce_template_single_title - 5
* @hooked woocommerce_template_single_rating - 10
* @hooked woocommerce_template_single_price - 10
* @hooked woocommerce_template_single_excerpt - 20
* @hooked woocommerce_template_single_add_to_cart - 30
* @hooked woocommerce_template_single_meta - 40
* @hooked woocommerce_template_single_sharing - 50
*/
do_action( 'woocommerce_single_product_summary' );
?>
</code></pre>
<p>And for example, when I want to edit this (delete some fields and change the structure) I try erase the string:</p>
<blockquote>
<p>do_action( 'woocommerce_single_product_summary' );</p>
</blockquote>
<p>and after that write like this:</p>
<pre><code><?php
/**
* woocommerce_single_product_summary hook.
*
* @hooked woocommerce_template_single_title - 5
* @hooked woocommerce_template_single_rating - 10
* @hooked woocommerce_template_single_price - 10
* @hooked woocommerce_template_single_excerpt - 20
* @hooked woocommerce_template_single_add_to_cart - 30
* @hooked woocommerce_template_single_meta - 40
* @hooked woocommerce_template_single_sharing - 50
*/
//do_action( 'woocommerce_single_product_summary' );
do_action('woocommerce_template_single_title');
?>
</code></pre>
<p>Could you tell me please why this doesn't work?</p>
<p>What is the right way to edit like that?</p>

<p>So, filter in ON clause seems not to work like I had expected. The filters <code>t1.c1 = t2.c1</code> and <code>t1.c1 = 2</code> hasn't been applied when, in the LEFT JOIN, it doesn't find the key on the second table so <code>t2.c2</code> is <code>NULL</code>.</p>
<p>I suppose that the answer must be in <a href="https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Joins" rel="nofollow">doc</a> (May be in the 'Joins occur BEFORE WHERE CLAUSES' section?) But still I don't understand the difference.</p>

ggplot: how to add common x and y labels to a grid of plots | <p>Using <code>diamonds</code>, I want to plot <code>carat</code> vs <code>price</code> for 4 levels (<code>Fair</code>, <code>Good</code>, <code>Very Good</code> and <code>Premimum</code>) of <code>cut</code>. </p>

<p>In all facets, x and y axes are the same. The only difference is the min, max and the breaks. I want to add x and y labels to this figure. I can do this manually in any word document or image editor. Is there anyway to do it in R directly?</p> | 0 |
How to plot dates on the x-axis using Seaborn (or matplotlib) | <p>I have a csv file with some time series data. I create a Data Frame as such:</p>
<pre><code>df = pd.read_csv('C:\\Desktop\\Scripts\\TimeSeries.log')
</code></pre>
<p>When I call <code>df.head(6)</code>, the data appears as follows:</p>
<pre><code>Company Date Value
ABC 08/21/16 00:00:00 500
ABC 08/22/16 00:00:00 600
ABC 08/23/16 00:00:00 650
ABC 08/24/16 00:00:00 625
ABC 08/25/16 00:00:00 675
ABC 08/26/16 00:00:00 680
</code></pre>
<p>Then, I have the following to force the 'Date' column into datetime format:</p>
<pre><code>df['Date'] = pd.to_datetime(df['Date'], errors = 'coerce')
</code></pre>
<p>Interestingly, I see "<code>pandas.core.series.Series</code>" when I call the following:</p>
<pre><code>type(df['Date'])
</code></pre>
<p>Finally, I call the following to create a plot:</p>
<pre><code>%matplotlib qt
sns.tsplot(df['Value'])
</code></pre>
<p>On the x-axis from left to right, I see integers ranging from 0 to the number of rows in the data frame. How does one add the 'Date' column as the x-axis values to this plot?</p>
<p>Thanks! </p> | 0 |
Running simple python script continuously on Heroku | <p>I have simple python script which I would like to host on Heroku and run it every 10 minutes using Heroku scheduler.

ASP.NET Core initialize singleton after configuring DI | <p>So let's say I have a singleton class instance that I register in the DI like this:</p>
<pre><code>services.AddSingleton<IFoo, Foo>();
</code></pre>
<p>And let's say the <code>Foo</code> class has a number of other dependencies (mostly repository classes that allow it to load data). </p>
<p>With my current understanding, the Foo instance is not created until it's first used (asked). Is there a way to initialize this class other than the constructor? Like right after <code>ConfigureServices()</code> completes? Or should the initialization code (loading data from db) be done in Foo's constructor?</p>
<p>(It would be nice if this class could load its data before the first use to speed up first time access)</p> | 0 |

How to wait for FirebaseAuth to finish initializing? | <p>Integrated Firebase Authentication to my app. Everything seems to be fine, until I noticed the issue wherein I open the app, it shows me the login screen, even though there is already a user signed in. </p>
<p>Exiting the app and launching it again solves the problem (app no longer asks the user to sign in again), though it provides the users a very bad experience.</p>
<p>I've read the docs, and apparently, calling <code>FirebaseAuth.getInstance().getCurrentUser()</code> might return null if auth haven't finished initializing. I'm assuming that's the reason why the issue happens. So I wonder if there is a way to wait for FirebaseAuth to finish its initialization before I can call getCurrentUser()?</p> | 0 |
read.csv() with UTF-8 encoding | <p>I am trying to read in data from a csv file and specify the encoding of the characters to be UTF-8. From reading through the ?read.csv() instructions, it seems that fileEncoding set equal to UTF-8 should accomplish this, however, I am not seeing that when checking. Is there a better way to specify the encoding of character strings to be UTF-8 when importing the data? </p>
<p>Sample Data: </p>
<p><a href="https://spaces.hightail.com/space/pwWp9" rel="noreferrer">Download Sample Data here</a></p>
<pre><code>fruit<- read.csv("fruit.csv", header = TRUE, fileEncoding = "UTF-8")
fruit[] <- lapply(fruit, as.character)
Encoding(fruit$Fruit)
</code></pre>
<p>The output is "uknown" but I would expect this to be "UTF-8". What is the best way to ensure all imported characters are UTF-8? Thank you. </p> | 0 |

Define arrays within array in Angular 2 and Typescript | <p>In Angular 2 I was wondering if it was possible to define an array that has multiple other arrays in it. It is probably easier to just show what I mean:</p>
<p>I started out using this:</p>
<pre><code>export class PaymentDetails {
account: any[];
bpNumber: number;
}
</code></pre>
<p>but this gave me the problem that when I populated it I couldn't really access the data in the account array, as I want more arrays inside of it.</p>
<p>So now i would like to define my class like this:</p>
<pre><code>export class PaymentDetails {
account: [
debitAccount: [
{
debitAccountId: string;
debitBankCode: string;
debitBankName: string;
debitCountryCode: string;
debitAccountNumber: string;
debitAccountHolder: string;
debitContinous: string;
debitDueDate: string;
iban: string;
bic: string;
}
],
ccAccount: [
{
ccAccountId: string;
ccCompanyCode: string;
ccNumber: string;
ccStart: string;
ccExpiry: string;
ccDsbTransactionId: string;
ccCardholderName: string
}
]
];
bpNumber: number;
}
</code></pre>
<p>Is this at all possible? </p>
<p>The class is getting populated with this InMemoryDataService</p>
<pre><code>export class InMemoryDataService {
createDb() {
let paymentDetailsDB = [
{
account: [
{
debitAccount: [
{
debitAccountId: '8736583',
debitBankCode: '45345',
debitBankName: 'KSK HGTT',
debitCountryCode: 'DE',
debitAccountNumber: '123453463',
debitAccountHolder: 'A Berg',
debitContinous: '',
debitDueDate: '',
iban: 'DE12344235',
bic: '324645',
},
{
debitAccountId: '6567456',
debitBankCode: '55463453',
debitBankName: 'GRDFE',
debitCountryCode: 'DE',
debitAccountNumber: '000123492',
debitAccountHolder: 'A Berg',
debitContinous: '',
debitDueDate: '',
iban: 'DE43523453',
bic: '123547665',
}
],
ccAccount: [
{
ccAccountId: '23413',
ccCompanyCode: '254345',
ccNumber: '238857827368837',
ccStart: '2010-10-05',
ccExpiry: '2018-10-05',
ccDsbTransactionId: '235231',

}
],
}
],

return {paymentDetailsDB};

Create an array with a sequence of numbers in bash | <p>I would like to write a script that will create me an array with the following values:</p>

for i in ${plist[@]}; do
echo "submit a simulation with this parameter:"
echo "$i"
done

Hibernate native query return List Object List | <p>I am using an hibernate NQL query which fetches me two columns :</p>

<p>When I select only one column i.e only object name - everything works fine but with two columns I am getting an error</p>
<blockquote>
<p>java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to
java.lang.String</p>

<p>at run time when I try to display result from the list. I tried using String array in the list as well but it doesn't work. Below are my code snippets which give error : </p>
<p>When I use only List : </p>
<pre><code>List<String> Thumbnailpaths = pathquery.list();
System.out.println(Thumbnailpaths.get(i).replace("\\", "\\\\"));
</code></pre>
<p>No error at compile time also nothing if leave it as it is but above line to display gives classcast exception.</p>
<p>When I use List array : </p>
<pre><code>List<String[]> Thumbnailpaths = pathquery.list();
System.out.println(Thumbnailpaths.get(i)[0].replace("\\", "\\\\"));
</code></pre>
<p>Here again classcast exception at runtime</p>
<p>Also <code>Criteria.ALIAS_TO_ENTITY_MAP</code> doesn't help at all as it makes logic much more complex. I just need 2 column values from a database table.</p>
<p>Please let me know if there is any solution to fetch multiple column results in NQL and then put in list.</p>
<p>Note : Looks like here generics are not displaying and only List is being written in my code snippet</p> | 0 |
Checking the error detection capabilities of CRC polynomials | <p>I tried to find out how to calculate the error detection capabilities of arbitrary CRC polynomials.</p>
<p>I know that there are various error detection capabilities that may (or may not) apply to an arbitrary polynomial:</p>
<ol>
<li><p>Detection of a single bit error:
All CRCs can do this since this only requires a CRC width >= 1.</p></li>
<li><p>Detection of burst errors:
All CRCs can detect burst errors up to a size that equals their width.</p></li>
<li><p>Detection of odd numbers of bit errors:
CRC with polynomials with an even number of terms (which means an even number of 1-bits in the full binary polynomial) can do this.</p></li>
<li><p>Detection of random bit errors (depending from frame size):
I have a ready-to-use C algorithm that allows calculating the maximum frame size for given HD and poylnomial. I didn't understood it completely but it works.</p></li>
</ol>
<p>Lets assume a 16 bit CRC polynomial x¹⁶+x¹²+x⁵+1 = 0x11021. That polynomial can:</p>
<ul>
<li>detect all single bit errors (data size independent).</li>
<li>detect all burst errors up to 16 bit width (data size independent).</li>
<li>detect all odd numbers of bit errors (since it has 4 polynomial terms; data size independent).</li>
<li>detect 3 bit errors (HD4) up to 32571 bit data size.</li>
</ul>
<p>Is the above correct?</p>
<p>Are there additional CRC error detection capabilities? If yes, how can I check (without deep math knowledge) if an arbitrary CRC polynomial supports them?</p> | 0 |
Odoo 500 server internal error after installation of odoo | <p>Hı all. Thank you for this community. I want use odoo for my job. but I'm so tired, I'm on the verge of giving up from odoo.</p>
<p>I would be very grateful if you help.</p>
<p>After installation, I can get once localhost8069 . And creating database.
ANd ı take create database error.</p>
<p>Database creation error: "invalid byte sequence for encoding "UTF8": 0xff " while parsing /usr/lib/python2.7/dist-packages/openerp/addons/base/base_data.xml:55, near <span>--<br/> Administrator</span> </p>
<p>After this error ı take always 500 internal server error. I can not see login interface anymore. I just see 500 internal server error.</p>
<p>6 days I'm working and I could not reach a solution. I used ubuntu and pardus ( some kind debian) . And the results did not change.</p>
<p>But when ı used w7 ı succeed. I was able to get odoo. But ı want use odoo in linux not windows.</p>
<p>I guess this error about database. But ı didnt find source about confıgure postgresql for odoo. Can you help me pls ?</p>
<p>This is my steps for installions of odoo after fresh ubuntu :</p>
<p>1-)</p>
<pre><code>wget -O - nightly.odoo.com/odoo.key | apt-key add -

</code></pre>
<p>2-) and go : <a href="http://localhost:8069" rel="nofollow">http://localhost:8069</a></p>
<p>Log file : ı erased log file and restart odoo server and try few time localhost:8069 again :</p>
<p>And this is end of new fresh log file :</p>

Installing angular-cli on Windows Behind Proxy Server | <p>I am currently building Angular 2 demos from behind a corporate proxy server with known issues for blocking both NPM and TypeScript 'typings' installs. While I have been able to work around these issues with proxy server settings, I'm a little unsure what to do about the latest issue.</p>
<p>Whenever I try to install angular-cli globally:</p>
<pre><code>npm install -g angular-cli
</code></pre>
<p>or even locally to a directory with an existing <strong>npm init</strong> setup (including package.json file):</p>
<pre><code>npm install angular-cli --save
</code></pre>
<p>I receive the following error (all local paths replaced with ):</p>
<p><strong>angular-cli npm install error</strong></p>
<pre><code>npm ERR! Error: EPERM: operation not permitted, rename
'C:\Users\<PATH>\node_modules\angular-cli\node_modules\babel-runtime' ->

Difference between RDBMS and ORDBMS | <p>It happened to me when I was reading about PostgreSQL on its <a href="https://en.wikipedia.org/wiki/PostgreSQL" rel="noreferrer">wiki</a> page where it refers to itself as an ORDBMS. I always knew about Microsoft SQL Server which is an RDBM system. Can someone help me understand the main differences between Relational Database Management System(RDBMS) and Object Relational Database Management System (ORDBMS) and in what scenarios should I use one of them?</p>
<p>Also, my key question is related to the fact that in the world of Microsoft SQL Server we often use a layer of Entity Framework (EF) to do the object relational mapping on the application side. So, in ORDBMS world are all the responsibilities of an ORM already fulfilled by the database itself in entirety or there could be use cases or scenarios where I would end up using an ORM like Entity Framework on top of ORDBMS as well? Do people really even use ORMs on top of an ORDBMS system?</p> | 0 |
ggplot2: reorder bars in barplot from highest to lowest | <p>I got this figure</p>

Can we Scaffold DbContext from selected tables of an existing database | <p>As in previous versions of Entity Framework, is it possible in Entity Framework Core to reverse engineer only the selected tables of an existing database to create model classes out of them. <a href="https://docs.efproject.net/en/latest/platforms/aspnetcore/existing-db.html" rel="noreferrer">This official ASP.NET site</a> reverse engineers the entire database. In past, <a href="http://www.asp.net/mvc/overview/getting-started/database-first-development/creating-the-web-application" rel="noreferrer">as shown in this ASP.NET tutorial</a>, using old EF you could reverse engineer only the selected tables/Views if you chose to.</p> | 0 |

How does Spring Boot control Tomcat cache? | <p>I'm porting 5 years old Spring MVC application with JSPs to Spring Boot.

log.info("Customizing tomcat factory. New cache size (KB) is " + cacheSize);
TomcatEmbeddedServletContainerFactory tomcatFactory = (TomcatEmbeddedServletContainerFactory) container;
tomcatFactory.addContextCustomizers((context) -> {
StandardRoot standardRoot = new StandardRoot(context);
standardRoot.setCacheMaxSize(cacheSize);
});
}
}
}

<p>Message about changing the cache size is in the logs, but the <strong>code above has no influence</strong> on the warnings</p> | 0 |
Should I use AWS Cognito "username" or "sub" (uid) for storing in database? | <p>I have an authenticated user in AWS Cognito service and want to store his unique identifier in the database. Should I store user's username (it's his phone number) or his "sub" (it's his uid)? All Amazon API functions like <a href="http://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_AdminGetUser.html" rel="noreferrer">AdminGetUser</a> are using "username" parameter, but not sub/uid.</p>
<p>But I also read that <a href="https://mobile.awsblog.com/post/Tx3JK25U7Z9EUIU/Integrating-Amazon-Cognito-User-Pools-with-API-Gateway" rel="noreferrer">article</a> and the author said "Always generate the policy on value of 'sub' claim and not for 'username' because username is reassignable. Sub is UUID for a user which is never reassigned to another user." </p>
<p>So, now I'm hesitating what I have to use as unique user identifier - "username" or "sub"</p>
<p>Thank you.</p> | 0 |
Table cell with nowrap overflows | <p>I'm using bootstrap, and want to create a simple HTML <code>table</code>, where in the last column I have a 2-button group and a single separate button. I want this last cell to always keep this 3 buttons in one line, so I added the <code>text-nowrap</code> bootstrap class (which is a simple <code>white-space: nowrap</code>).</p>
<p>If the content of the other cell(s) is long enough, the content of the last cell will overflow horizontally, and I don't understand why. I'd expect that the rest of the table will shrink to make space for the non-wrapping cell.</p>
<p>Here is a demo to reproduce the issue: <a href="http://www.bootply.com/wWM2a9R8Mt" rel="nofollow">bootply</a></p>
<p>Here is the markup.</p>
<pre><code><div style="width: 500px">
<table class="table table-striped">
<tbody><tr>
<td>Test text</td>
<td class="text-nowrap">
<div class="btn-group">
<button class="btn btn-default"><span>A</span></button>
<button class="btn btn-warning"><span>B</span></button>
</div>
<button class="btn btn-success"><span>C</span></button>
</td>
</tr>
</tbody></table>
</div>
</code></pre>
<p>The button group <code>div</code> and the separate <code>button</code> are all <code>inline-block</code> elements, so the wrapping should work as expected IMO. What am I doing wrong?</p>
<p>Maybe this is not strictly related to bootstrap.</p>
<p><strong>UPDATE</strong></p>
<ul>
<li>I've updated the bootply, the link was a previous version, sorry</li>
<li>Tested in latest Chrome and IE, the issue is almost the same in both.</li>
</ul>
<p><strong>The cause and the workaround</strong></p>
<ul>
<li>I've realized that unwrapping the two buttons from the <code>btn-group</code> will result a correct layout, so I started to examine what actually the <code>btn-group</code> does.</li>
<li>I've found that the <code>btn</code>s in the <code>btn-group</code> are floated, and this floating causes the bad layout. <del>Adding a <code>clearfix</code> class to the <code>btn-group</code> solves the issue.</del> No it actually doesn't, still researching...</li>
<li>I will examine why the <code>float: left</code> is needed for bootstrap, it seems like the buttons in the group could be aligned by using purely <code>inline-block</code> without margin. I will check this in the <code>v4-alpha</code> code, and will also report this issue to bootstrap <code>v3</code>.</li>

Spring Boot and MongoDB - how to save date | <p>I've followed the Spring.io guide for accessing MongoDB data with rest (<a href="https://spring.io/guides/gs/accessing-mongodb-data-rest/" rel="noreferrer">https://spring.io/guides/gs/accessing-mongodb-data-rest/</a>) and can save documents into mongo.</p>
<p>When I try to add a date field into the POJO and set the date as a <code>new Date()</code> object, it just saves the value as null when it saves to mongo.</p>
<p>I've created an extremely basic <code>@RestController</code> which is working fine (passes in the request body, and saves it down using my <code>MongoRepository</code> class), saving documents via the rest console. I tried creating a new date in here and setting it before saving it down to Mongo but this gives me something like <code>"createdDate": 1472394366324</code>.</p>
<p>I can save dates as a string into Mongo, but what I want is to be able to save dates in the date format so I can query them with a basic 'date between' query (so something like this, the exact format doesn't matter much - <code>"date" : ISODate("2014-02-10T10:50:42.389Z")</code>. I can write the queries to get values via parameters, but to get the 'date between' query working I need to be able to store date values into Mongo.</p>
<p>What is the easiest way to accomplish this?</p>
<p>Edit:</p>
<p>Pojo class -</p>
<pre><code>import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.format.annotation.DateTimeFormat;

<p>I found almost the same exception here: <a href="https://stackoverflow.com/questions/32029093/could-not-fetch-model-of-type-eclipseproject-using-gradle">Could not fetch model of type 'EclipseProject' using Gradle</a>
but the solution was to use the latest Gradle version (currently 3.0)</p>
<p>The same scenario was reported on <a href="https://discuss.gradle.org/t/could-not-fetch-model-error-when-converting-project-to-gradle-using-buildship/19022" rel="nofollow noreferrer">https://discuss.gradle.org/t/could-not-fetch-model-error-when-converting-project-to-gradle-using-buildship/19022</a> but with no answers so far.</p>
<p>The reported resource is available for download: <a href="https://services.gradle.org/distributions/gradle-3.0-bin.zip" rel="nofollow noreferrer">https://services.gradle.org/distributions/gradle-3.0-bin.zip</a></p>
<p>Does anybody have workarounds for this problem? Thank you.</p> | 0 |
