"First, why does uf.is_valid() return" because you called "uf.is_valid" (note the lack of parenthesis), that's just a reference to the method and does not call it.
"Second, why does uf.save() return that stacktrace the first time I call it, but the second time I call it, the object saves? " As far as I know ModelForm subclasses take a dictionary as a first parameter, not the object itself, you would need to do something like this: uf = UsersForm(instance=u) I don't know why it works the second time (if it does indeed work) On Sun, Jan 3, 2016 at 1:13 AM, Sergiy Khohlov <[email protected]> wrote: > Sorry I missed.
