SQLAlchemy supports adding common functionality from a class to many other
classes through mixin classes. OpenAlchemy supports this through the
x-mixins extension property.
- SQLAlchemy mixin documentation
Documentation for SQLAlchemy mixin.
The following rules apply to the
x-mixins extension property:
it can either be a string or a list of strings each of which defines one of the mixin classes and
each value must be the fully qualified dotted name of the class to use as the mixin. Everything before the last dot will be used to import the module and everything after will be used to retrieve the class from the module.
The following example adds the
sqlalchemy_mixins.TimestampsMixin to the
1 2 3 4
Employee: type: object x-mixins: sqlalchemy_mixins.TimestampsMixin ...
Alternatively, multiple mixins can be defined using a list:
1 2 3 4 5 6
Employee: type: object x-mixins: - sqlalchemy_mixins.TimestampsMixin - sqlalchemy_mixins.EagerLoadMixin ...
- sqlalchemy_mixins package
Package that defines some helpful SQLAlchemy mixins.
