A simple constructor that allows initialization from kwargs.

Sets attributes on the constructed instance using the names and values in kwargs.

Only keys that are present as attributes of the instance’s class are allowed. These could be, for example, any mapped columns or relationships.

query: t.ClassVar[Query]

A SQLAlchemy query for a model. Equivalent to db.session.query(Model). Can be customized per-model by overriding query_class.

Warning

The query interface is considered legacy in SQLAlchemy. Prefer using session.execute(select()) instead.
