On the surface, that look like it should work. Which makes me suspect
some important detail has been lost in the simplification.
What does the my_data dictionary look like just before you execute the
"form = ..." line (print it out)?
Also, how is form_class specified? Finally, what is the exact error
Django gives you? Print out form._errors, for example.
Maybe somewhere in there the answer will jump out. Admittedly, all the
clues may already be there and I'm just missing the obvious, but I can't
see it right now.
On a related note, is there any particular reason you need to have
site_id in the form class at all? Even if it's a model form, you could
exclude it, and add it into the model object later, couldn't you? You
might be going about this slightly backwards by trying to force in
site_id when it's not something that actually needs to be validated or
form-processed.
