Pretend to have in the Django admin, 2 forms inlines, Each with a pair of
fields choices, "Attributes" and "Value Option". We have the first pair,
which initialize the field one with a value, for example color and other
field you must have a queryset the choices.
[[Image(http://i.stack.imgur.com/kk1xQ.png)]]
As you can see We need to filter each pair with their default values, if
Color should show only white, black and blue.
{{{
class ProductAttributeValueForm(forms.ModelForm):
attribute = forms.ModelChoiceField(label=_('Attribute'),
widget=forms.Select(attrs={'disabled': 'True'}),
queryset=ProductAttribute.objects.all(), required=False)
class ProductAttributeValueFormSet(BaseInlineFormSet):
def __init__(self, *args, **kwargs):
super(ProductAttributeValueFormSet, self).__init__(*args,
**kwargs)
# This return initial [{'attribute' initial}, {..}, {..}]
self.initial = [{'attribute': a} for a in
obj.category.attributes.all()]
# Now we need to make a queryset to each field of each form inline
self.queryset = [{'value_option' .. }, { .. }]
}}}
What I do is initialize each attribute with a value, for example, Color
and passed a queryset to value_option with their respective values, white,
blue and black. I have tried to do this two days ago and I have not
accomplished anything, not if the solution is on the forms or in any
function of admin.
if I could just iterate a QuerySet each model choice of the form. The only
thing achieved is that a queryset applies to all forms inline, but I need
a different one for each inline.
{{{
def formfield_for_foreignkey(self, db_field, request, **kwargs):
if db_field.name == "value_option":
kwargs["queryset"] = request._obj_.category.attributes.all()
return super(AttributeInline, self).formfield_for_foreignkey(db_field,
request, **kwargs)
}}}
So, if you have Attribute: Color, Size, ROM, RAM, the ideal would happen
to a custom list value_options each.
