create nested JSON from DB output in django rest framework -


i trying create nested json db output, using django rest framework. have created models, serializers , views.py follows:

models.py

class secondmodel(models.model):     userno = models.charfield(max_length=30, primary_key=true)     username = models.charfield(max_length=250)     period = models.charfield(max_length=250)      class meta:         managed = false         db_table = 'view1'  class firstmodel(models.model):     code = models.foreignkey(secondmodel,db_column='code',              related_name='clients', primary_key=true)     name = models.charfield(max_length=250)     study = models.charfield(max_length=250)     class meta:         managed = false         db_table = 'view2'

views.py:

class nestedviewset(viewsets.modelviewset):     serializer_class = secondserializer     queryset = secondmodel.objects.filter(userno=11)     serializer = secondserializer(instance=queryset)

serializers.py:

class firstserializer(serializers.modelserializer):     class meta:         model = firstmodel         fields = ('name', 'code', 'study')    class secondserializer(serializers.modelserializer):     clients = firstserializer(many=true,read_only=true)     class meta:         model = secondmodel         fields = ('userno', 'username','period','clients')

the output getting below. getting "clients" empty list.

{    "userno": "11", "username": "smith,john", "period": "apr-17", "clients": []

}, {
"userno": "11", "username": "smith, john", "period": "apr-17", "clients": [] }

the output looking is:

{ "userno": "11", "username": "smith,john", "period": "apr-17", "clients": [     {         "name" : "comp1",         "code" : "abc111",         "study" : "stu11"     },     {         "name" : "comp2",         "code" : "abc222",         "study" : "stu22"     } ]

}

am missing here desired output?
