objectfactory is a python package to easily implement the factory design pattern for object creation, serialization, and polymorphism

  • designed to support polymorphism
  • integrates seamlessly with marshmallow and other serialization frameworks
  • schema inherent in class definition
  • load any object with a generic interface
  • serialize objects to JSON

Example

Simple shapes example:

import objectfactory

@objectfactory.register
class Square( objectfactory.Serializable ):
    side = objectfactory.Field()

    def get_area( self ):
        return self.side * self.side

@objectfactory.register
class Triangle( objectfactory.Serializable ):
    base = objectfactory.Field()
    height = objectfactory.Field()

    def get_area( self ):
        return 0.5 * self.base * self.height

serialized_data = [
    {"_type": "Square", "side": 2.0},
    {"_type": "Triangle", "base": 1.75, "height": 2.50},
    {"_type": "Square", "side": 1.5},
]

for data in serialized_data:
    shape = objectfactory.create( data )
    print( 'class type: {}, shape area: {}'.format( type( shape ), shape.get_area() ) )

Output:

class type: <class '__main__.Square'>, shape area: 4.0
class type: <class '__main__.Triangle'>, shape area: 2.1875
class type: <class '__main__.Square'>, shape area: 2.25

    This PR integrates marshmallow as the underlying serialization framework. This includes:

    • create new abstract base class (ABC) for objects and fields
    • dynamically define marshmallow schema from object definition
    • use schema de/serialization
    • implements enforced fields for primitive types (string, int, float, bool)
    • nested marshmallow field for nested objects and lists
    • support optional custom marshmallow schema
    • new and up[dated examples
    • refactor and expand testing
