[BUG] foreign key with or without `_id`

[sigma-plus]

Describe the bug The same foreign key field serializer result changes (with or without _id ) when another api is added.

Versions (please complete the following information):

• Python version: 3.11.1
• Django version: 4.2.5
• Django-Ninja version: 0.22.2
• Pydantic version: 1.10.12

The minimal setup is :

class TestModel(models.Model):
    department = models.ForeignKey(Department, on_delete=models.CASCADE)


class TestModelSchema(ModelSchema):
    class Config:
        model = models.TestModel
        model_fields = "__all__"


@router.get("/test_model", response=List[TestModelSchema])
def get_test_model(request):
    return models.TestModel.objects.all()

Schema in docs page says the expected results is something like:

[
  {
    "id": 0,
    "department": 0
  }
]

but when I add another api:

@router.put("/test_model/{test_model_id}", response=TestModelSchema)
def update_test_model(request, test_model_id: int, payload: TestModelSchema):
    obj = get_object_or_404(models.TestModel, pk=test_model_id)
    for attr, value in payload.dict().items():
        setattr(obj, attr, value)
    obj.save()
    return obj

department field changes to department_id in both api docs, the real get api result is still department, which is really confusing.

updated to 1.0, the bug still exists.

Still happening on 1.1

I've the opposite :/

In data I've category_id But in payload.dict() I've category. And since it's a number django throws an error

    raise ValueError(
ValueError: Cannot assign "379": "Software.category" must be a "Category" instance.
