rest framework错误笔记——AssertionError: Cannot apply DjangoModelPermissionsOrAnonReadOnly on a view that does not set `.queryset` or have a `.get_queryset()` method.

用到@api_view装饰器时，访问路由查看api数据时，报错：

AssertionError: Cannot apply DjangoModelPermissionsOrAnonReadOnly on a view that does not set `.queryset` or have a `.get_queryset()` method.

按照官网教程（http://www.django-rest-framework.org/），在settings文件里写入的设置为

REST_FRAMEWORK = {

    # Use Django's standard `django.contrib.auth` permissions,

    # or allow read-only access for unauthenticated users.

    'DEFAULT_PERMISSION_CLASSES': [

        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'

    ]

}

将设置里的'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'一句删除，重启项目再次访问，不在报错。

　　注：'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly'适用于添加身份验证和权限以后。
