How to create data when define ForeignKey in the model

[dlpuzcl]

Hi guys

I have a problem, it occurs the error when defining ForeignKey in the model. below is my code.
code

class Menu(Model):
    parent = models.ForeignKey(to='Menu', on_delete=models.CASCADE, verbose_name="parent ", null=True, blank=True)
    icon = models.CharField(max_length=64, verbose_name="icon", null=True, blank=True)
    title = models.CharField(max_length=64, verbose_name="title")
    permission = models.CharField(max_length=64, verbose_name="permission " )
    order_no = models.IntegerField(default=1, verbose_name="order_no", null=True, blank=True)
    creator = models.ForeignKey(to=settings.AUTH_USER_MODEL, null=True,verbose_name=creator ', on_delete=models.SET_NULL)

class SchemaIn(ModelSchema):

    class Config:
        model = Menu
        model_exclude = ['id']


class SchemaOut(ModelSchema):
    class Config:
        model = Menu
        model_fields = "__all__"

@router.post("/menu", response=SchemaOut)
def create_post(request, data: SchemaIn):
    post = Menu.objects.create(**data.dict())
    return post

Error info
Cannot assign "0": "Menu.creator" must be a "Users" instance.

As the hint says, creator must be a instance. I think you need this.

Example:

@router.post("/menu", response=SchemaOut)
def create_post(request, data: SchemaIn):
    data.creator = User.objects.get(data.creator)
    post = Menu.objects.create(**data.dict())
    return post

You can also do this to ensure that the code does not report errors

@router.post("/menu", response={200: SchemaOut, 404: str})
def create_post(request, data: SchemaIn):
    user = User.onjects.filter(id=data.creator).first()
    if not user:
        return 404, "User does not exist"
    data.creator = user
    post = Menu.objects.create(**data.dict())
    return post
