from sqlalchemy.orm import declarative_base  

ContentBase = declarative_base()

# session  
from src.db.base import BroadcastBase, ContentBase, MujadwilBase  

content_db_engine = create_engine(  
    f"sqlite:///{CONTENT_DB_PATH}",  
    connect_args={"check_same_thread": False},  
    json_serializer=lambda obj: json.dumps(obj, ensure_ascii=False),  
)  
broadcast_db_engine = create_engine(  
    f"sqlite:///{BROADCAST_DB_PATH}", connect_args={"check_same_thread": False}  
)  

ContentBase.metadata.create_all(bind=content_db_engine)  
BroadcastBase.metadata.create_all(bind=broadcast_db_engine)  

session = scoped_session(  
    sessionmaker(  
        autocommit=False,

        binds={  
            ContentBase: content_db_engine,
