How can I apply a filter to a sqlAlchemy query based on a boolean field?

edit

To apply a filter to a SQLAlchemy query based on a boolean field, you can use the filter() method and pass in the boolean column along with its desired boolean value. For example:

from sqlalchemy import create_engine, Column, Integer, Boolean
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base

engine = create_engine('sqlite:///example.db')
Base = declarative_base()

class User(Base):
    __tablename__ = 'users'

    id = Column(Integer, primary_key=True)
    name = Column(String)
    is_active = Column(Boolean)

Session = sessionmaker(bind=engine)
session = Session()

# Filter for all active users
active_users = session.query(User).filter(User.is_active == True).all()

# Filter for all inactive users
inactive_users = session.query(User).filter(User.is_active == False).all()

In this example, we define a User model with an isactive boolean column. We then create a session and query all users that have a True value for isactive (activeusers), and all users that have a False value (inactiveusers). The filter() method is used to apply the boolean condition to the query.
