title: Load Django Form Object with data from Model instance already "loaded"
body: <p>I have the following type of template in Django:</p>
  
  <pre><code>    &lt;form .... &gt;
        &lt;label class="control-label" for="id_quantity"&gt;Quantiy&lt;/label&gt;
        {{ form.quantity }}
  
        &lt;label class="control-label" for="id_title"&gt;Quantiy&lt;/label&gt;
        {{ form.title}}
  
      &lt;/form&gt;
  </code></pre>
  
  <p>The view contains a ModelForm object in its context from which the "form" variable in the template is derived.</p>
  
  <p>Often, you can pass a form that is bound to data like request.POST. How do I load a form that is bound to the data of a specific instance of a model? Is there any special syntax?</p>
