It doesn't have to be a callable, you can just do something like:
recipientUser = ShowValidContactList(currentUser=self.currentUser)
I never used that kwargs.pop function (I didn't know you could do that),
but I have code like this:
class ExperimentForm(ModelForm):
""" Generate form to handle experiment information. """
def __init__(self, user, *args, **kwargs):
super(ExperimentForm, self).__init__(*args, **kwargs)
try:
preferences = Preferences.objects.get(user=user)
That last 'user' is just what came from the function call in the view.
