Description (last modified by )
Hello!
I have this function using json and a queryset with defer() method, but the fields not target in queryset, i need only "id" and "nome":
models.py
class Pessoa(models.Model): nome = models.CharField(max_length=50) data_nascimento = models.DateField() data_inclusao = models.DateField() cpf = models.CharField(max_length=14) telefone = models.CharField(max_length=13) celular = models.CharField(max_length=13) class Meta: abstract = True class Proprietario(Pessoa): endereco = models.ForeignKey(Endereco) def __unicode__(self): return "%s, %s" % (self.nome, self.cpf)
views.py:
def load_proprietarios(request): data = serializers.serialize('json',Proprietario.objects.defer('cpf','telefone','celular','data_nascimento','data_inclusao',),ensure_ascii=False)) return HttpResponse(data, mimetype="application/javascript")
This is the output:
[{"pk": 1, "model": "proprietario.proprietario_deferred_celular_cpf_telefone_data_inclusao_data_nascimento", "fields": {}}]
Note that the "id" and the "nome" fields (class Proprietario / class abstract Pessoa) does not appear after defer() method.
Regards.

Summary: | Queryset which uses defer() method not serialize in Json → Queryset which uses defer() method not serialize |

The bug seems to apply to all serializers, not only JSON.

I tested this on the current master branch and this no longer seems to be a problem.

This bug report should be simplified with a simpler model and view as given below.
models.py:
view.py:
Output:
Specifying fields to the serializer like below, gives the same result.
The same issue also applies when using .only().
I would argue that when fields are not specified to the serializer, the entire object should be loaded and serialized.
