marshmallow-meta

decorator syntax for marshmallow meta attributes (with inheritance)

Decorators communicate that the behavior of a class is being modified and are more concise when only a few meta attributes are needed. Making inheritance the default further reduces the boilerplate needed to make minor changes to a subclass.

Install

pip install marshmallow-meta

from marshmallow_meta import meta

API

@meta(*kwargs)

Build a meta class that inherits attributes from the base schema's meta class.

@meta(unknown=INCLUDE)
class Test(Schema):
    foo = fields.String()

@meta(*bases, **kwargs)

Inherit and extend specific meta classes.

@meta(Test.Meta, many=True)
class CopyCats(Schema):
   bar = fields.String()

Or clear the inherited meta class.

@meta(Schema.Meta)
class Fresh(CopyCats):
   buzz = fields.String()
