Tools to convert SQLAlchemy models to Pydantic models
最后发布版本: 0.0.9 ( 2021-05-30 17:38:06)
Pydantic-SQLAlchemy
Tools to generate Pydantic models from SQLAlchemy models.
Still experimental.
🚨 WARNING: Use SQLModel instead 🚨
SQLModel is a library that solves the same problem as this one, but in a much better way, also solving several other problems at the same time.
This project was to solve some simple use cases, to generate dynamic Pydantic models from SQLAlchemy models. But the result cannot be used very well in code as it doesn't have all the autocompletion and inline errors that a Pydantic model would have.
This was a very simple implementation, SQLModel is a much better solution, much better design and work behind it.
For most of the cases where you would use pydantic-sqlalchemy
, you should use SQLModel instead.
How to use
Quick example:
from typing import List
from pydantic_sqlalchemy import sqlalchemy_to_pydantic
from sqlalchemy import Column, ForeignKey, Integer, String, create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import Session, relationship, sessionmaker
Base = declarative_base()
engine = create_engine("sqlite://", echo=True)
class User(Base):
__tablename__ = "users"
id = Column(Integer, primary_key=True)
name = Column(String)
fullname = Column(String)
nickname = Column(String)
addresses = relationship(
"Address", back_populates="user", cascade="all, delete, delete-orphan"
)
class Address(Base):
__tablename__ = "addresses"
id = Column(Integer, primary_key=True)
email_address = Column(String, nullable=False)
user_id = Column(Integer, ForeignKey("users.id"))
user = relationship("User", back_populates="addresses")
PydanticUser = sqlalchemy_to_pydantic(User)
PydanticAddress = sqlalchemy_to_pydantic(Address)
class PydanticUserWithAddresses(PydanticUser):
addresses: List[PydanticAddress] = []
Base.metadata.create_all(engine)
LocalSession = sessionmaker(bind=engine)
db: Session = LocalSession()
ed_user = User(name="ed", fullname="Ed Jones", nickname="edsnickname")
address = Address(email_address="ed@example.com")
address2 = Address(email_address="eddy@example.com")
ed_user.addresses = [address, address2]
db.add(ed_user)
db.commit()
def test_pydantic_sqlalchemy():
user = db.query(User).first()
pydantic_user = PydanticUser.from_orm(user)
data = pydantic_user.dict()
assert data == {
"fullname": "Ed Jones",
"id": 1,
"name": "ed",
"nickname": "edsnickname",
}
pydantic_user_with_addresses = PydanticUserWithAddresses.from_orm(user)
data = pydantic_user_with_addresses.dict()
assert data == {
"fullname": "Ed Jones",
"id": 1,
"name": "ed",
"nickname": "edsnickname",
"addresses": [
{"email_address": "ed@example.com", "id": 1, "user_id": 1},
{"email_address": "eddy@example.com", "id": 2, "user_id": 1},
],
}
