Question

我正在尝试使用django-rest-framework-mongoengine来构建使用Django和mongodb的Web服务。

当我添加一个列出Document类型对象的网址时出错。

我的模型文件是

class Job(Document):
    title = StringField(required=True)
    state = StringField(required=True)

我的观点是

class JobViewSet(GenericAPIView):
    queryset = Job.objects.all()
    serializer_class = JobSerializer

我的网址文件是

router = routers.MongoSimpleRouter()
router.register(r'jobs', views.JobViewSet)

urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

我的序列化程序是

class JobSerializer(DocumentSerializer):
    class Meta:
        model = Job
        fields = ('title', 'state')

当我执行runserver

时出现以下错误

`base_name` argument not specified, and could not automatically determine the name from the viewset, as it does not have a `.model` attribute.

我尝试了不同的视图类型，但所有相同的错误。非常感谢任何帮助....

我正在使用

python 2.7.9
Django==1.7.7 
django-rest-framework-mongoengine==2.0.2    
mongoengine==0.9.0

Answer 1

您需要添加base_name参数才能使其正常工作：

router = routers.MongoSimpleRouter()
router.register(r'jobs', views.JobViewSet, 'job-view')

我试试这个（来自Geo Jacob的回答），但不起作用：

router.register(r'jobs', views.JobViewSet, base_name='job-view')

注意：请注意base_name='job-view'和'job-view'

之间的区别

Answer 2

尝试在路由器寄存器中添加base_name。

router = routers.MongoSimpleRouter()
router.register(r'jobs', views.JobViewSet, base_name='job-view')

当我在django Mongoengine Web服务url.py文件中包含我的视图时，为什么会出现base_name属性错误？
