python - PostgreSQL ILIKE query with SQLAlchemy

Question

I'd like to run a query that selects all posts, case insensitive, that have titles that match '%' + [some_phrase] + '%'. That is, select all rows that have titles that contain some phrase, case insensitive. From the research I've done, it looks like I need to use Postgres's ILIKE query for it to match case insensitive. How can I execute a query like this with SQLAlchemy?

class Post(db.Model):
    id = db.Column(db.Integer, primary_key = True)
    title = db.Column(db.String(250))
    content = db.Column(db.String(5000))

Answer 1

I think it should work

Post.query.filter(Post.title.ilike('%some_phrase%'))
