FormWizard don't process multipart forms

[Damian Świstowski <damian@…>]

get_form method creating form only with request.POST parameter, adding request.FILES resolves problem.

This patch still applies cleanly.

This is a borderline feature addition, and without tests I'm reluctant to check it in this late. I'm going to push post-1.0; if someone can get a (passing) test written by 8/30, pop this back to the 1.0 milestone and I'll check it in.

This thing should be documented somehow, documentation reads (now):
"""Important limitation: Because the wizard uses HTML hidden fields to store data between pages, you may not include a FileField in any form except the last one."""

I'd say you cannot include a FileField on *any* form neither the last one, as request.FILES never gets passed around. Until this gets fixed we should tell people that their files will be left in limbo! ;)

(Or I did something really bad and I should really be getting my files on the last form! :)

add raise when multipart form is not as last

Perhaps I did something wrong, but when I tried implementing the patches (by overriding get_form and call in my FormWizard subclass), I get a "Please upload a valid image. The file you uploaded was either not an image or a corrupted image." error every time with an ImageField.

Now I just did a hack and maybe this might help somebody

Line 117: f = self.get_form(i, request.POST)
Change to: f = self.get_form(i, request.POST, request.FILES)

Line 131: form = self.get_form(current_step, request.POST)
Change to: form = self.get_form(current_step, request.POST, request.FILES)

Line 46 of the get_form method: def get_form(self, step, data=None)
Change the signature to: def get_form(self, step, post=None, files=None):

Then you should be fine.But there's a caveat though, your file must be on the last form also you cannot have two select options on the same page.
I don't know why that is a problem. Still checking whats is wrong. Also I would love to know if anyone has been able to make the form go back i.e. using a previous and next button. I'm working on that now though but if someone has fixed that. Would be glad to know.
I hope this helps somebody.
