What is the ormar way to create an entity with relations via Fastapi?

[Strernd]

I have some models with different many to many relationships. For the sake of simplicity assume we have the two models Chocolate and Assortment a Chocolate can be in different Assortments and a Assortment contains multiple different Chocolate entities.

I've created endpoints with Fastapi for chocolate and created some entities and have their ids.
Now I want to create an Assortment by passing

{
  "name": "Finest Selection",
  "price": 10,
  "chocolates": ["abcd-1234-chocid-01", "abcd-1234-chocid-02"]
}

to the POST /assortment endpoint. Of course I want to add the Chocolate entities to the Assortment entity by only passing the ids.

I haven't found a way for this that seems to be intended.
Do I have to break down the pydantic model (so that it ignores the ids) and then call assortment.chocolates.add(...) for every Chocolate entity that I need to fetch from the database?

If you want to save the whole tree in one call you can call Model.save_related(follow=True, save_all=True). It will upsert all models including nested children, with through models for m2m relations too.

As of now add only accepts the model instance but will look into it.
