Error using ModelResource: can't set attribute - django

Question

I can't get my head around this error... I'm using the restframework2 branch.
Am I doing something wrong, or is this a bug in the restframework2 code?
Here's my code:
resources.py
class TemplateHoursSerializer(serializers.ModelSerializer):
class Meta:
model = TemplateHours
nested = True
start = HourField()
end = HourField()
employee = EmployeeSerializer()
class TemplateHoursResource(ModelResource):
model = TemplateHours
serializer_class = TemplateHoursSerializer
urls.py
url(r'^api/template-hours/$', TemplateHoursResource.as_view(actions={
'get': 'list',
'post': 'create'
})),
url(r'^api/template-hours/(?P<pk>[0-9]+)/$', TemplateHoursResource.as_view(actions={
'get': 'retrieve',
'put': 'update',
'delete': 'destroy'
})),
...
When I visit (or POST to) http://127.0.0.1:8000/api/template-hours/, I get this error and traceback:
AttributeError at /api/template-hours/
can't set attribute

Resources and routers are not finished/supported in [the beta of] REST framework 2 yet. The docs on them are a placeholder for what I want the design to look like, but I'll be removing them from the index today. Hopefully they'll make it in for 2.0, but I don't see it as at all essential, since you can do everything you need with Views and explicit URLconfs. Resources & routers just give you a useful shortcut.
