About

FieldsManageMixin provides dynamic processing of serializer fields.

Usage

FieldsManageMixin provides dynamic processing of serializer fields
via methods "exclude_fields" and "include_fields" directly from python 
code or by GET-params from HTTP-requset

Access by code:

# serializers.py
class MyFirstLevelSerializer(FieldsManageMixin, serializers.Serializer):
    first_field_1 = serializers.IntegerField()
    first_field_2 = serializers.CharField()
    first_field_3 = serializers.CharField()
    first_field_4 = MySecondLevelSerializer()

class MySecondLevelSerializer(serializers.Serializer):
    second_field_1 = serializers.IntegerField()
    second_field_2 = serializers.CharField()
    second_field_3 = serializers.CharField()
    second_field_4 = serializers.CharField()
    
class MyModelSerializer(FieldsManageMixin, serializers.ModelSerializer):
    
    class Meta:
        model = MyModel
        fields = ('model_field_1', 'model_field_2', 'model_field_3', 
                  'model_field_4', 'model_field_5', 'model_field_6',)
....

    
# views.py
class MyViewInclude(generics.GenericAPIView):
    serializer_class = MyFirstLevelSerializer.include_fields(
        'first_field_2','first_field_4{second_field_2;second_field_4}',
    )
    
class MyViewExclude(generics.GenericAPIView):
    serializer_class = MyModelSerializer.exclude_fields(
        'model_field_3','model_field_6',
    )    
...
        
Access by GET-params (works first level only):
    
# views
class MyView(generics.GenericAPIView):
    serializer_class = MyModelSerializer
    ....
