Reverse version of sql LIKE in sqlalchemy [duplicate]

问题

This question already has an answer here:

how to pass a not like operator in a sqlalchemy ORM query (1 answer)

Closed 6 years ago.

By "reverse version of like" I mean exactly like this question. The question is how to make a query like that in sqlalchemy?

I found out that to make "SELECT LIKE" query in sqlalchemy I should make something like that

session.query(Book).filter(Book.title.like("%"+my_title+"%"))

Because like is method of column, I don't know how to use like method to ask about "%" + Book.title + "%".

Thanks to this question, I figure out how to do that :)

session.query(Book).
    filter(bindparam('book_title', book.title).contains(Book.title)).first()
