AttributeError: 'ContactForm' object has no attribute 'clean_data'
``clean_data`` will always *only* contain a key for fields defined in the
``Form``, even if you pass extra data when you define the ``Form``. In this
example, we pass a bunch of extra fields to the ``ContactForm`` constructor,
but ``clean_data`` contains only the form's fields::
>>> data = {'subject': 'hello',
... 'message': 'Hi there',
... 'sender': 'foo@example.com',
... 'cc_myself': True,
... 'extra_field_1': 'foo',
... 'extra_field_2': 'bar',
... 'extra_field_3': 'baz'}
>>> f = ContactForm(data)
>>> f.is_valid()
True
>>> f.clean_data # Doesn't contain extra_field_1, etc.
{'cc_myself': True, 'message': u'Hi there', 'sender': u'foo@example.com', 'subject': u'hello'}
