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:

    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.
