Rather than listing all the key word arguments (kwargs) like that, you
are better doing it like this:
import logging # probably a better way than writing to debug.txt, but
clearly it is personal choice
def __init__(self, *args, **kwargs):
instance = getattr(kwargs, 'instance')
logging.debug("First name: %s" % instance.user.first_name) # I
like to know what it thinks it is printing!
logging.debug("Last name: %s" % instance.user.last_name) #
obviously you can change str if you like
super(ProfileForm, self).__init__(data, *args, **kwargs)
I don't know if this will fix your problem (hard to say without
visibility of the view), but it may be that you have forgotten one of
the kwargs. If you want to add extra parameters, or set them to
specific values you can still do this before calling init.
