1 year ago I have created a minimum viable codes to illustrate this problem:
from typing import List, Optional, Any
from sqlmodel import Field, SQLModel as _SQLModel, Relationship
from slugify import slugify
from datetime import date, datetime
from pydantic import validator
from sqlalchemy.orm import declared_attr
class SQLModel(_SQLModel):
@declared_attr # type: ignore
def __tablename__(cls) -> str:
return cls.__name__
class Config:
use_enum_values = True
class BaseIDModel(SQLModel):
id: Optional[int] = Field(
primary_key=True,
index=True,
nullable=False,
)
class ProjectBase(SQLModel):
is_active: bool = Field(default=True, nullable=False)
name: str = Field(nullable=False)
publish_date: date = Field(
default_factory=datetime.now().date, nullable=False)
repr_name: Optional[str] = Field(default=None, nullable=False)
approved: bool = Field(default=False, nullable=False)
featured: bool = Field(default=False, nullable=False)
# post_init
@validator("repr_name", pre=True, always=True)
def slugify_name(cls, v, values) -> str:
if v is None:
print(f"{v=}, {values=}")
return slugify(values["name"], separator="_")
raise ValueError(
f"`repr_name` cannot be passed in as a parameter to the `Request`.")
class Project(BaseIDModel, ProjectBase, table=True):
pass
class IProjectCreate(ProjectBase):
pass
if __name__ == '__main__':
Project.from_orm(IProjectCreate(name='Hello A'))The Output is:
v=None, values={'is_active': True, 'name': 'Hello A', 'publish_date': datetime.date(2023, 2, 18)}
v=None, values={'is_active': True, 'publish_date': datetime.date(2023, 2, 18)}

Let's supposed I have the following model and
createschema.As you can see, I am trying to post-process the
namefield by 'slugify' it.The
ICreateProjectschema is as follows:As I try to create a project using the API, with the following request:
The error log I got is this:
Somehow, the
from_ormmethod does not have the fieldname.
