Enumerate Priority Levels with SQLAlchemy-Utils
In below code, establishes an SQLite in-memory database and defines a Task model using SQLAlchemy-Utils' ChoiceType to represent enumerated priority levels. The ChoiceType ensures that the 'priority' column can only have values chosen from a predefined set: 'Low', 'Medium', and 'High'. The declarative base class, declarative_base(), is utilized to create the base for the model, and the table is named 'tasks'.
Python3
from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy_utils import ChoiceType
engine = create_engine("sqlite:///:memory:")
Base = declarative_base()
class Task(Base):
__tablename__ = 'tasks'
id = Column(Integer, primary_key=True)
name = Column(String, nullable=False)
priority = Column(ChoiceType(choices={'low': 'Low', 'medium': 'Medium', 'high': 'High'}), nullable=False)
Base.metadata.create_all(engine)
Output:
