title: django: form.fields not iterating through instance fields
body: <p>I am trying to iterate through form.fields in a template and for:</p>
  
  <pre><code>{% for field in form.fields %}
     {{ field }}, 
  {% endfor %}
  </code></pre>
  
  <p>I am getting a list of the field names ("name, description...") instead of the html code that is rendered when using the following:</p>
  
  <pre><code>{{ form.name }}, {{ form.description }}
  </code></pre>
  
  <p>(the output in this case is: </p>
  
  <p><strong>&lt;input id="id_name" type="text" name="name" maxlength="200" /&gt;&lt;input id="id_description"....</strong></p>
  
  <p>Any hints?
  Thanks!</p>
