Return A Nested List Of One Model

I have a lookups table that contains course categories and subcategories separate: { 'id': 138, 'lookup': 'CRS_CTGRY', 'attr1': 'Arts and Humanities',

Solution 1:

You need to implement serializer for your subcategory:

classSubcategorySerializer(serializers.ModelSerializer):
      classMeta:
          model = Lookupsfields= ( 'id', 'lookup', 'attr1', 'attr2', 'attr3',)

And use it in your Category Serializer when you select all related subcategories:

classCategorySerialier(serializers.ModelSerializer): 
      subcategories =  serializers.SerializerMethodField(read_only=True)

      classMeta:
          model = Lookups
          fields = ( 'id', 'lookup', 'subcagories')

      defget_subcategories(self, obj):
          subs = Lookups.objects.filter(attr3=obj.id)
          return SubcategorySerializer(subs,many=True).data

Solution 2:

If these are two models, and one serialize inside the other. http://www.django-rest-framework.org/api-guide/relations/#nested-relationships
