   @mik-laj FYI SQLAlchemy has some linter-friendly functions to avoid e.g. `== None` and make linters happy:
   
   ```python
   query.filter(User.name == None)
   
   # linter friendly equivalent:
   query.filter(User.name.is_(None))
   ```
   
   More here: https://docs.sqlalchemy.org/en/13/orm/tutorial.html#common-filter-operators
