24,128,759 | 0 | <p>It's not actually a Django question but rather a ORM question, you need to understand what and how ORM works (apart from the language and the framework used). Your case yields different results:</p> <p>1 Bridge can Have Many workers (One (bridge) <--* Many (Worker), ForeignKey)</p> <p>1 Bridge can have 1 worker (One (Bridge) <--> One (Worker), One To One field)</p> <p>Many Bridges can have many workers (Many (Bridges) * -- * many (Workers), Many to Many field)</p> <p>If you use a ForeignKey from tools to builders, it means that a worker can have many tools, but each tool is unique to a worker, if you have many to many then any worker can have any tool. If you need tools to belong to many different workers, then you need a many to many relation, if the tools need some specific restrictions (like skills) then again a many to many relation with specific limitations (a through table could hold extra information regarding the association, like worker 1 uses tool 1 every friday, that would be a through table of workers to tools with the middle table holding the day the worker uses the specific tool).</p> |

5,735,763 | 0 | <p>Which version of VS are you using? </p> <p>Not sure what you mean by "registered in any project", but here's a starting point: You can obtain a list of all .h and .cpp files by doing (recursive) directory listings from the root directory. Since the solution and the project files are just .xml files(in later versions of VS at least), you can just use regular expressions to pull out all the referenced .h and .cpp files and then cross reference the list you got doing directory listings with the ones you can parse from project files. In your case your simple directory structure makes the searching a little simpler.</p> <p>If by your second point you mean "included by another source or header" then I guess you have to read all .h and .cpp files and search for #include statements, but this would make the program a little more complex.</p> |
3,666,359 | 0 | <p>In addition to Boltclock's answer, there's a difference in how css walks through the DOM, which can have an effect on the processing speed of the stylesheet.

21,681,941 | 0 | Visualize JSF facelets inclusion <p>This is a simple question: is there a tool or method that allows me to visualize from what set of Facelet template files my view is constructed?</p> <p>Background: I find myself constantly searching for popups and reusable chunks I have stashed away in their own little facelets. Now if one is causing issues, I have to go down a hierarchy of includes to figure out which view is actually including the facelet. Right now this means I'm searching all template files for component id strings, then for each of the files that include that string, I search for the filename of that template, then lookup all templates that <code>ui:include</code> that file until I find a file that is not mentioned in an <code>ui:include</code> tag.</p> <p>I imagine that there must be a tool that visualizes this as a tree/forest structure for any given search term. Is there? And if not, how would you go about writing one?</p> |

12,680,134 | 0 | <blockquote> <p>Not sure why it acts like that tho.. The CSS folder is in the same folder as the actual php file.</p> </blockquote> <p>You've linked to it using a relative URI:</p> <pre><code><link rel="stylesheet" type="text/css" media="all" href="./css/text.css" /> </code></pre> <p>e.g. the <code>./css/text.css</code>, and while the css file may be in the same directory as <code>picture.php</code> file (which I assume is what is generating the content) but the browser is what actually makes the request for the CSS, not the picture.php script. The browser requests this URL <code>http://www.mysite.com/picture/1</code>, and the server internally rewrite the <code>/picture/1</code> to <code>/picture.php?id=1</code>, the browser has no clue that's happened. So it sees the base URI as <code>/picture/</code>. If the browser went directly to the php file: <code>http://www.mysite.com/picture.php?id=1</code>, the base URI would be <code>/</code> and the css would resolve just fine to <code>/./css/text.css</code>. But the <code>/picture/1</code> request has a different base URI so the browser (with no clue that the base is different) blindly attempts to retrieve the css as <code>/picture/./css/text.css</code>, which fails because you have rules that mishandle that URI. Normally you'd just get a 404, but the rules you have after the picture rewrite mishandles the URI and returns a 500 server error.</p> <p>You can either add in your header:</p> <pre><code><base href="/"> </code></pre> <p>in the content generated by <code>picture.php</code>, or make the URI's absolute:</p> <pre><code><link rel="stylesheet" type="text/css" media="all" href="/css/text.css" /> </code></pre> |

I've created the hub, uploaded my certificates, started coding but I couldn't find the equivalent of my previous code.

6,427,893 | 0 | <p>Ok, you have some serious issues here. Orders have mulitple items, invoices have multiple orders and payments may apply to mulitple orders and invoices. Orders may appear on multiple invoices (if they don't pay right aways which is common).</p> <p>So what you need are linking tables. You should start with an ORDERINVOICE table which has both the order id and the invoice ID. Then an ORDERPAYMENT table with paymentid and Order id. </p> <p>You also need to consider that in an ordering situation, you must record the details of the order as it occurred at the time. That means that while you should have the user_id to link to the current user, you should record the user's name, billing address and shipping addres as it was at the time of the order. You will need this information later to deal with any questions on the order. Further you need to ensure that you store the details of the order in a separate table called ORDERDETAILS which store the indivdual line items, the price at the time of the order and the name of the item ordered. You will need this for accounting reasons. You do not under any cuircumstances want to rely on a join to a product table to figure out the price of an order in the past. This will cause your finanacial records to be inaccurate.</p> |

I'm trying to read from a queue. I'm not 100% positive if my logic is correct in my code, but anytime I try to run my app I am greeted with this exception (I've included only the last section):</p> <pre><code>Caused by: com.ibm.msg.client.commonservices.CSIException: JMSCS0002 at com.ibm.msg.client.commonservices.workqueue.PIWorkQueueManager.enqueueItem(PIWorkQueueManager.java:67) at com.ibm.msg.client.commonservices.workqueue.WorkQueueManager.enqueue(WorkQueueManager.java:225) at com.ibm.msg.client.commonservices.workqueue.WorkQueueManager.enqueue(WorkQueueManager.java:194) at com.ibm.msg.client.wmq.common.internal.WMQThreadPool.enqueue(WMQThreadPool.java:91) </code></pre> <p>Now I'm fairly certain this has nothing to do with my code because no matter how much I change my logic, if I try calling any of the methods made available by <code>JMSTemplate</code>, I receive this exception.

15,866,199 | 0 | C standard: L prefix and octal/hexadecimal escape sequences <p>I didn't find an explanation in the C standard how do aforementioned escape sequences in wide strings are processed.</p> <p>For example:</p> <pre><code>wchar_t *txt1 = L"\x03A9"; wchar_t *txt2 = L"\xA9\x03"; </code></pre> <p>Are these somehow processed (like prefixing each byte with \x00 byte) or stored in memory exactly the same way as they are declared here?</p> <p>Also, how does L prefix operate according to the standard?</p> <p><strong>EDIT:</strong></p> <p>Let's consider txt2. How it would be stored in memory? \xA9\x00\x03\x00 or \xA9\x03 as it was written? Same goes to \x03A9. Would this be considered as a wide character or as 2 separate bytes which would be made into two wide characters?</p> <p><strong>EDIT2:</strong></p> <p>Standard says:</p> <p>The hexadecimal digits that follow the backslash and the letter x in a hexadecimal escape sequence are taken to be part of the construction of a single character for an integer character constant or of a single wide character for a wide character constant. The numerical value of the hexadecimal integer so formed specifies the value of the desired character or wide character.</p> <p>Now, we have a char literal:</p> <pre><code>wchar_t txt = L'\xFE\xFF'; </code></pre> <p>It consists of 2 hex escape sequences, therefore it should be treated as two wide characters. If these are two wide characters they can't fit into one wchar_t space (yet it compiles in MSVC) and in my case this sequence is treated as the following:</p> <pre><code>wchar_t foo = L'\xFFFE'; </code></pre> <p>which is the only hex escape sequence and therefore the only wide char.</p> <p><strong>EDIT3:</strong></p> <p>Conclusions: each oct/hex sequence is treated as a separate value ( wchar_t *txt2 = L"\xA9\x03"; consists of 3 elements). wchar_t txt = L'\xFE\xFF'; is not portable - implementation defined feature, one should use wchar_t txt = L'\xFFFE';</p> |

It has two separate effects. First, it automatically chomps $/ (the input record separator) when used with -n or -p. Second, it assigns $\ (the output record separator) to have the value of octnum so that any print statements will have that separator added back on.</p> </blockquote> <p>Here is what Deparse makes of it:</p> <pre><code>perl -MO=Deparse -p00le 's/\n/ \\\n/g' BEGIN { $/ = ""; $\ = "\n\n"; } LINE: while (defined($_ = <ARGV>)) { chomp $_; s/\n/ \\\n/g; } continue { print $_; } </code></pre> |
