How can I do multiple “order_by” in Flask-SQLAlchemy?

Question

Let\'s say I have a User model with fields popularity and date_created. I want to do the following query:

SELECT * FROM us         


        

Answer 1

What you also could do:

from sqlalchemy import and_, or_
User.query.order_by(and_(User.popularity.desc(), User.date_created.desc())).all()

Note: and_ and or_ are coming from the sqlalchemy library and not from flask_sqlalchemy library. sqlalchemy is a dependency for flask_sqlalchemy, so you should be good.

LTS: You can mix sqlalchemy lib with flask_alchemy lib

Answer 2

I have another example:

user = User.query.order_by(User.id.desc()).limit(10).all()

s.t

User is my class db.Modle

Answer 3

This should work

User.query.order_by(User.popularity.desc(),User.date_created.desc()).limit(10).all()
