@ -404,6 +404,36 @@ Here's a simple function that might drive the above form::

form = forms.FormWrapper(manipulator, new_data, errors)
return render_to_response('contact_form.html', {'form': form})
``FileField``s and ``ImageField``s
==================================
Dealing with for ``FileField`` and ``ImageField`` is a little more
complicated.
First, you'll need to make sure that your ``<form>`` element correctly defines
the ``enctype`` in order to upload files::
<form enctype="multipart/form-data" method="POST" action=".">
Next, you'll need to treat the field in the template slightly differently.
Given a field in the model::
photo = model.ImageField('/path/to/upload/location')
You need to actually display two formfields in the template:
<p><label for="id_photo">Photo:</label> {{ form.photo }}{{ form.photo_file }}</p>
The first bit (``{{ form.photo }}``) displays the currently-selected file,
while the second (``{{ form.photo_file }}``) actually contains the file upload
form field. Thus, at the validation layer you need to check the ``photo_file``
key.
Finally, in the view, make sure to call ``new_data.update(request.FILES)``::
new_data = request.POST.copy()
new_data.update(request.FILES)
