Example Code
from pydantic import BaseModel
from sqlmodel import SQLModel, Field
class BaseModelTest(BaseModel):
id: int
some_bool: bool
desc: str
class SQLModelTest(SQLModel, table=True):
id: int = Field(default=None, primary_key=True)
some_bool: bool
desc: str
# This will work as expected
sqlmodel_instance = SQLModelTest(id=3, some_bool=False, desc="This will work")
print(sqlmodel_instance)
# This will work as expected
pydantic_instance = BaseModelTest(id=3, some_bool=False, desc="This will work")
print(pydantic_instance)
# This will work but should not
sqlmodel_instance = SQLModelTest(id=3, some_bool="blob", desc=False)
print(sqlmodel_instance)
# This will not work as expected
pydantic_instance = BaseModelTest(id=3, some_bool="blob", desc=False)
print(pydantic_instance)Description
When creating a SQLModel class instance, I thought that I'd have all the advantages of pydantic and SQLAlchemy classes toghether.
I was quite surprised when I realized that SQLModel classes created with table=True do not validate data as a pydantic class would do (see my example code).
Having read about all SQLModel documentation, I didn't find anywhere this is stated.
Especially in https://sqlmodel.tiangolo.com/tutorial/fastapi/multiple-models/ it would make sense to explain that a table=True won't do data validation as a pydantic class would do.
Maybe I did not understand the purpose of SQLModel enough, but this is quite disturbing for me.
I think it would be really nice to update the documentation regarding this particular point.
