title: Peewee - Update an entry with a dictionary
body: <p>I found <a href="https://stackoverflow.com/questions/22750439/peewee-how-to-convert-a-dict-into-a-model">this handy answer</a> on how to <strong>create</strong> a new table entry using a dictionary.</p>
  
  <p>Now i'd like to <strong>update</strong> an entry with the same method. but i don't know how to adress the specific table entry that i'd like to update. </p>
  
  <p>My current version looks like this:</p>
  
  <pre><code>entries = Fruit.select().order_by(Fruit.name.desc())
  #... all entries are listed with the index number
  entry_index = int(input("Please enter entry number: "))
  #...
  entry_index -= 1
  
  name = "Banana"
  color = "yellow"
  
  if input('Update entry? [Yn] ').lower() != 'n':
          entries[entry_index].name = name
          entries[entry_index].color = color
  </code></pre>
  
  <p>As you can see i adress every field explicitly.
  I would like to put the variables (name, color) in a dictionary and update the entry at position "entry_index" with the fore-mentioned double-star-shortcut <a href="https://stackoverflow.com/questions/22750439/peewee-how-to-convert-a-dict-into-a-model">like in this answer</a>.
  But i can't find a <a href="http://docs.peewee-orm.com/en/latest/peewee/querying.html#updating-existing-records" rel="nofollow">proper method in the docs</a>. </p>
  
  <p>Does anyone know how to accomplish that?</p>
  
  <p>Thanks for your help!</p>
