Form Mixins with multilayered M2M models

[Ali khan]

Hi,

I have three models like below:

Shop:

         |

          Products

                        |

                        Variations

Where Shop has a ForeignKey for products and then products has foreign key for variations. So Shop has no ForeignKey with Variations directly instead connected via Products model.

1. I am new to Django and I need to understand that in ShopListView view how to reference variations.

2. Also I need to create a form using FormSetFactory where I can grab data from all the models in hierarchy. Like my form should have edit options for Shop's own model fields with Products model fields and Variation Fields.

Would appreciate any help.

Regards,

Ali
