how to pass a not like operator in a sqlalchemy ORM query
I've got a query:
MyModel.query.filter(Mymodel.name.contains('a_string'))
I need to do the same query but with the negation (a not like operator) but didn't find any operator matching my need in the SQLAlchemy documentation.
Is there any way to do it without using the sql part of SQLAlchemy???
Solution 1:
Just negate the filter:
MyModel.query.filter(sqlalchemy.not_(Mymodel.name.contains('a_string')))
Solution 2:
There is now a notlike() method. Couldn't find it in the docs but it exists!
MyModel.query.filter(Mymodel.name.notlike('%a_string%'))
