I have two issues:
1) When I use photo_form.save() I get: (1048, "Column 'user_id' cannot
be null"), despite the fact that the user is in the POST data:
description: u'my desc'
user: u'2'
2) I wrote:
pre_data = {'user': request.user.id }
photo_form = PhotoForm(pre_data)
And there is a HiddenInput for User ForeignKey in the PhotoForm
But is there any other way to pass the information about User?
