Django Admin Forms with additional fields in ManyToMany relations

Question

I have 2 Entities with a ManyToMany Relation and some additional fields, here you can find an example diagram:

I created all models following the documentation and everything works, but I would also manage MTM relations using django admin without use another form to create a new "WheelsCar" row that links togheter a car and a wheel. Is it possible? How?

Admin use case:

1. I click on add new Car
2. I select one of the wheels, filling the additional fields (position, holes...)
3. Iterate step 2
4. Save a New Car

Answer 1

I got it, I have to use Inline Fields!
