question

version

fastapi: 0.63.0
pydantic: 1.8.1
tortoise-orm: 0.17.1

# model
class Order(Model):
    created_at = fields.DatetimeField(auto_now_add=True, null=False)

    def created_at_(self):
        return self.created_at.strftime('%Y-%m-%d %H:%M:%S')

# pydantic schema
class Schema(BaseModel):
    created: str = Field(..., alias='created_at_')

    class Config:
        orm_mode = True

# api
@router.get('', response_model=Schema)
async def read():
    Creator = pydantic_model_creator(Order, exclude=('created_at',), compused=('created_at_',))

    query = await Order.filter(id=q_id).first()
    order = Creator().from_tortoise_orm(query)

    print(order)
    # there is created_at_
    print(Schema.from_orm(query))
    # there is created
    return order

but the api return is {"created_at_": "..."} not {"created": "..."}

and how to use alias Field(..., alias='created_at_')

What is pydantic_model_creator and compused parameter?

[panla]

from tortoise.contrib.pydantic import pydantic_model_creator, pydantic_queryset_creator

Creator = pydantic_model_creator(Order, exclude=exclude, compused=compused)

It seems like this would be a question for Tortoise, not for FastAPI, it's probably better to ask there.

Sorry for the long delay! 🙈 I wanted to personally address each issue/PR and they piled up through time, but now I'm checking each one in order.
