#18214: Serializers do not serialize iterators
--------------------------------------+------------------------------------
Reporter: moritzs | Owner: nobody
Type: Bug | Status: new
Component: Core (Serialization) | Version: SVN
Severity: Normal | Keywords: serialization json xml
Triage Stage: Unreviewed | Has patch: 0

--------------------------------------+------------------------------------
According to [https://docs.djangoproject.com/en/dev/topics/serialization/
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:
{{{
#!python
>>> 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.
