使用ModelResource時出錯：無法設置屬性

我無法理解此錯誤......我使用的是restframework2分支。使用ModelResource時出錯：無法設置屬性

我做錯了什麼，或者這是restframework2代碼中的錯誤？

這裏是我的代碼：

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' 
})), 
...

當我訪問（或POST到）http://127.0.0.1:8000/api/template-hours/，我得到這個錯誤和回溯：

資源和路由器尚未在[REST框架2的測試版]中完成/支持。他們的文檔是我想讓設計看起來像的一個佔位符，但我今天將從索引中刪除它們。希望他們能夠在2.0中實現它，但是我認爲它並不重要，因爲你可以通過Views和顯式URLconf來完成你所需要的一切。資源&路由器只是給你一個有用的捷徑。
