This stopped working in Django 1.8[1] :
"Class-based views that use ModelFormMixin will raise an ImproperlyConfigured
exception when both the fields and form_class attributes are specified.
Previously,
fields was silently ignored."
And burried in the docs[2], a different case for the same thing:
In older versions, omitting both fields and exclude resulted in a form with all
the
model’s fields. Doing this now raises an ImproperlyConfigured exception.
For someone who didn't follow the discussion on the topic, it sure is hard to
find in
release notes.

The model form is missing a 'fields' attribute. Example:
*class ComponentStockAllocationAssign(*StockMixin, generic.CreateView*):
*model
*= *models.ComponentLocationStock *_fields _**_= ['component', 'location',
'stock']_*
success_url *= *reverse_lazy*("component_allocation_list")

That's a much bigger question than it seems. What's the relation between the
forms?
If they're unrelated, implement get_context_data() to assign them, and
form_valid() to
process them.
