Django form with __init__ doesn't clean fields

I have a django form I'm attempting to add CAPTCHA support to. However, this requires me to pass request.session to the form. To accomplish that, I added this constructor to the form:

def __init__(self, request=None, *args, **kwargs):
    super(RegistrationForm, self).__init__(*args, **kwargs)
    self.request = request

I then instantiate the RegistrationForm by passing the request object to it. However, when submitting the form, it fails to clean any of the fields. It just fails validation and passes a blank field back to the template. Here is the registration code that fails:

if request.method == 'POST':
    form = RegistrationForm(request.POST)
    if form.is_valid():
        ...do registration...
    else:
        return render(request, 'template.htm', {'form': form})

No matter what I put in the fields, it never validates. In fact, it doesn't even look like it cleans the fields. I just get back a new blank form after hitting the register button, no errors, nothing.

Any ideas?

Based on the code you posted, it looks as though you are passing request.POST into the request parameter for your RegistrationForm. i.e. you are doing the equivalent of:

form = RegistrationForm(request=request.POST)

What you really want to do is this:

form = RegistrationForm(request=request, data=request.POST)

Try this and see if it works for you.
