How do you define a basic SQLAlchemy model?
← All SQLAlchemy questions
Re-explain
A SQLAlchemy model is defined by creating a class that inherits from a declarative base and includes table metadata:
from sqlalchemy import Column, Integer, String, create_engine
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
Base = declarative_base()
class User(Base):
__tablename__ = 'users'
id = Column(Integer, primary_key=True)
name = Column(String(50), nullable=False)
email = Column(String(100), unique=True)
def __repr__(self):
return f"<User(name='{self.name}', email='{self.email}')>"
