python - How to delete a record by id in Flask-SQLAlchemy

Question

I have users table in my MySql database. This table has id, name and age fields.

How can I delete some record by id?

Now I use the following code:

user = User.query.get(id)
db.session.delete(user)
db.session.commit()

But I don't want to make any query before delete operation. Is there any way to do this? I know, I can use db.engine.execute("delete from users where id=..."), but I would like to use delete() method.

Answer 1

You can do this,

User.query.filter_by(id=123).delete()

or

User.query.filter(User.id == 123).delete()

Make sure to commit for delete() to take effect.
