How to serialise the Model with the list containing querysets of that model?

class DummyModel(models.Model):
      dummyId             =        models.AutoField(primary_key=True)
      assetId              =        models.CharField(max_length=250)
      bounds               =        models.CharField(max_length=1000)

Now i have dummylist containing queryset of DummyModel

dummylist=[<QuerySet [<DummyModel>]>, <QuerySet [<DummyModel>]>]

Now i have serialiser like this

class DummySerialiser(serialiser.ModelSerialiser):

     class Meta:
         model=DummyModel

Now i need to generate a json in with list of dummymodel 

{ 
  {"dummyId":1,
    ....
  },
  {"dummyId":2,
   ....
  }
}

Any pointers on this would be a great help. Thanks in advance.!!

create your serializer like this

class DummySerialiser(serialiser.ModelSerialiser):

     class Meta:
         model = DummyModel
         fields = ('dummyId', 'assetId', 'bounds',)

In your view use many=True to serialize list of objects

queryset = DummyModel.objects.all() # assume this is your queryset
serializer = DummySerialiser(queryset, many=True)
dummylist = serializer.data # you will get your required json data

Add many=True in serializer, while serializing the data to serialize a list of objects

my_serializer = DummySerialiser(dummylist,many=True)

You'll get the required data from my_serializer.data
