Django response return empty array

Question

I'm trying to retrieve a list from django class based views and i'm getting the below output in my response

[{},{}]

The model currently has two items in it.

below is my views.py

class CategoryList(generics.ListCreateAPIView):
    renderer_classes = (JSONRenderer,TemplateHTMLRenderer,BrowsableAPIRenderer)
    template_name = 'create.html'
    queryset = Category.objects.all()
    serializer_class = CategorySerializer

models.py

class Category(models.Model):
    category = models.CharField(max_length = 100)

below is my ajax call:

  function getcategories(){
    $.ajax({
      type: 'GET',
      url: 'http://127.0.0.1:8000/billing/categories',
      contentType: 'application/json',
      crossDomain:true,

      success : function(json){
        for (var i = 0; i < json.length; i ++){
        $('#category-row').append('<td>'+json[i].category + '</td>');
        console.log('success');
        console.log(json.length);
      }
    },
      error : function(){
        console.log('there was an error with category-get');
      }
    });

  };

where am I going wrong?

Post the code for serializer also.

The problem is probably in your serializer class. It doesn't know how to convert your model into json. It is getting a list of two items, but since it cannot convert them it just puts an empty object.
