Thank you for your help. I apologize for the typo, but I am calling
is_valid() with the parenthesis:
>>> uf = UsersForm(u)
>>> uf.is_valid()
Traceback (most recent call last):

AttributeError: 'Users' object has no attribute 'get'
>>> uf.is_valid()
True
As for creating the form instance with the instance keyword, I tried that
first as I saw it in the materials I was reading, but it doesn't work. Note
the code below. is_bound = False if I use instance=u. If I just pass the
Users instance without the 'instance' keyword, is_bound returns True.
>>> u = Users()
>>> u.email = '[email protected]'
>>> uf = UsersForm(u)
>>> uf.is_bound
True
>>> uf = UsersForm(instance=u)
>>> uf.is_bound
False
