Description (last modified by )
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.
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.
