如何修复 django 中的循环导入？

Question

我正在尝试创建一个将带有电子邮件的图像上传到数据库的 api。但我收到错误“raise ImproperlyConfigured(msg.format(name=self.urlconf_name))”是我的 urls.py 中的问题吗？

这就是我的结构的样子

这是错误

对于 urls.py-

from django.contrib import admin
from django.urls import path,include
from django.conf import settings

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('user.urls')),
    path('api/',include('api_test.urls'))
    # path('articles/',include('articles.urls'))

]

对于 api_test/urls.py

​​>

from django.urls import path,include
from django.conf import settings
from . import views

from rest_framework import routers

router = routers.DefaultRouter()
router.register('image_test',views.api_test,base_name='image_test')

urlpatterns = [
    # path('/',views.api_test),
    path('',include(routers.url)),


]

views.py

​​>

class api_test(viewsets.ModelViewSet):
    queryset = fineDB.objects.all()
    serializer_class = fineSerializer

##for serializers.py

from rest_framework import serializers
from .models import fineDB

class fineSerializer(serializers.ModelSerializer):
    image = serializers.ImageField(max_length=None,use_url=True)
    class Meta:
        model = fineDB
        fields = {'email','image'}

您可能应该从router 获取网址，而不是routers。 同时，您不需要该文件中的路由器和 urlpatterns。你可以导入路由器并将它的router.urls挂载到urls.py中。

from rest_framework import routers

router = routers.DefaultRouter()
router.register('image_test',views.api_test,base_name='image_test')

urlpatterns = [
    # path('/',views.api_test),
    path('',include(router.urls)),    # <-


]
