Example Code

from typing import Optional

from pydantic import BaseModel
from sqlmodel import Field, SQLModel

class User1(SQLModel, table=True):
    id: Optional[int] = Field(primary_key=True)
    name: str

class User2(BaseModel):
    name: str

User1()
User2()

Description

  • Create SQLModel
  • Create equivalent pydantic model
  • Create instance of SQLModel without providing required arguments
  • Create instance of pydantic model without providing required arguments

The pydantic model raises an ValidationError whereas the SQLModel doesn't raise a ValidationError even though an required argument is not provided. I would expect a ValidationError if not all required arguments is provided.
