you probably want to use passive_deletes=True as well so that collections
aren't loaded in for unnecessary, individual DELETEs:

Note to self: read docs better.
I had to add a cascade='delete' in the backref. I tried this the first
time, but put it in the relationship instead of the backref.
class Post(Base):
__tablename__ = 'posts'
id = Column(Integer, primary_key=True)
title = Column(String(255), nullable=False)
body = C
Assuming I define my tables using the following:
CREATE TABLE users (
id SERIAL NOT NULL,
username VARCHAR(255) NOT NULL,
PRIMARY KEY (id),
UNIQUE (username)
)
CREATE TABLE posts (
id SERIAL NOT NULL,
title VARCHAR(255) NOT NULL,
body TEXT NOT NULL,
user_id INTEGER,
PRIMARY KEY (id),
FOREIGN KEY(
Okay it works
literal() and literal_column() functions works with sqlite but only
literal() function works with MySQLdb connector
Thanks a lot !)
