Does not work, why? remember, we need get each form inline.... guided on
the next line
self.initial = [{'attribute': attribute} for attribute in obj.category.
attributes.all()]
# Important: This start each form with a different value, [{'attribute':
'Colors'}, {'attribute': 'Sizes'}, ..]
if you do this right, it will be a value equal to all forms, including
doing this does not work takes the last forloop and entered.
for choices in AttributeOptions.objects.filter(attribute=attribute): # This
return 2 objects
self.fields['value_option'].queryset = choices # We thought at first
sight that works, but what this does is take the last forloop.
I think this should be some kind or bug in Django, because should operate
at the level of form, something like this.
self.fields.queryset = [{'value_option': choices1}, {'value_option':
choices2} ... ]
We should open a ticket for this?
