Django-模型和序列化程序类，最好的方法

Question

firstly let me explain the situation. I have a model that basically have a title and a TextField that will save a json:

class Content(UUIDObject):
    title = models.CharField(_(u"Title"), max_length=300)
    custom_fields_json = models.TextField(_(u"Settings"))

To create this json, I must use a serializer class, from django rest framework. This class doesn't have a link to any model.

class ConfigSerializer(serializers.Serializer):
    provider = serializers.CharField(write_only=True, required=True)
    provider_id = serializers.CharField(write_only=True, required=True)

The class above must be used to offer the user a form so he can fill title (from content model), provider and provider_id . The resulting json from the serializer class will be stored at custom_fields_json . The serializer class used in dynamic and I have the logic to return it working properly.

Currently I have a CreateView/UpdateView and adapting the code from this guide I can render the form with all the fields.. but then I just can't get the json from the serializer, etc...

I'm starting to think that this is the wrong way of doing it. I would like to ask to guys with more experience if there is a better way of doing it, and what would it be.

Thanks

Use the ModelSerializer:

class ConfigSerializer(serializers.ModelSerializer):
    class Meta:
        model = Content
        fields = ('title', 'custom_fields_json')

The serializer can give you a dict. Also read about ModelViewSets in django rest framework, they can significally minimize your code.
