Question

我无法理解这个错误...我正在使用restframework2分支。

我做错了什么，或者这是restframework2代码中的错误？

这是我的代码：

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'
})),
...

当我访问（或POST）http://127.0.0.1:8000/api/template-hours/时，我收到此错误并追溯：

REST框架2的[测试版]尚未完成/支持资源和路由器。关于它们的文档是我希望设计看起来像的占位符，但我今天将从索引中删除它们。希望他们能够在2.0版本中使用它，但我认为它根本不是必需的，因为你可以使用Views和显式URLconf来完成所需的一切。资源与资源路由器只是给你一个有用的捷径。

使用ModelResource时出错：无法设置属性
