Serializers do not serialize iterators

[Moritz Sichert]

According to ​serialization documentation the given object "can be any iterator that yields Django objects, but it'll almost always be a QuerySet". But it does not work with iterators.

Example:

>>> from django.core import serializers
>>> json_serializer = serializers.get_serializer('json')()
>>> json_serializer.serialize([1, 2, 3])
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "trunk/django/core/serializers/base.py", line 46, in serialize
    concrete_model = obj._meta.concrete_model
AttributeError: 'int' object has no attribute '_meta'
>>>
>>> xml_serializer = serializers.get_serializer('xml')()
>>> xml_serializer.serialize([1, 2, 3])
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "trunk/django/core/serializers/base.py", line 43, in serialize
    self.start_object(obj)
  File "trunk/django/core/serializers/xml_serializer.py", line 42, in start_object
    raise base.SerializationError("Non-model object (%s) encountered during serialization" % type(obj))
SerializationError: Non-model object (<type 'int'>) encountered during serialization

One should either change the documentation or make this work.

that yields Django objects. [1, 2, 3] are not Django objects. Accepting on the base that what are Django objects might be more clearly explained in the documentation.

Did you purposely left the first occurrence of "Django objects" in the first paragraph?

[Alex Ogier]

Good point, that wasn't deliberate.

I did not realize that it reads 'Django objects'. Thank you for the hint!
