django ModelSerializer 将变量传递给 meta sub-class

Question

我，试图找到最干净的实现来从 django 序列化程序

中的元子class访问上下文

views.py:

import someapp.models as models
import someapp.serializers as serializer

def some_view(request, batch_id):
    exp_type = models.UploadModel.objects.filter(batch_id=batch_id).values()[0]['experiment_type']
    model_idx = get_obj_idx_from_exp(model_names, exp_type)
    use_model = model_objs[model_idx]
    model_data = use_model.objects.filter(batch_id=batch_id)
    list_data = serializer.GeneralSerializer(model_data, many=True, context={'model': use_model}).data
    ...

serializers.py

from rest_framework.serializers import ModelSerializer
from someapp import models

class GeneralSerializer(ModelSerializer):
    # can access self.context['model'] here
    class Meta:
    # can NOT access self.context['model'] here
    model = self.context['model']
    fields, _ = zip(*self.context['model'].display_fields())

serializers.py

class GeneralSerializer(serializers.ModelSerializer):

    class Meta:
        model = None

views.py

class GeneralViewSet(viewsets.ModelViewSet):

     def get_queryset(self):
         model = self.kwargs.get('model')
         return model.objects.all()           

     def get_serializer_class(self):
         GeneralSerializer.Meta.model = self.kwargs.get('model')
         return GeneralSerializer
