Question

我很难过要使用反向功能来实现我的DRF实现。这是我的urls.py，我将假设使用以下反向操作：

urls.py

 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.arahasya.sap.forwardkey/com.arahasya.sap.forwardkey.MainActivity}: android.view.InflateException: Binary XML file line #27: Binary XML file line #27: Error inflating class TextView

然后

from django.conf.urls import url, include
from rest_framework import routers
from . import views
router = routers.DefaultRouter()
router.register(r'compressors', views.CompressorViewSet, base_name='compressors')
from django.urls import include, path
# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    url(r'^', include(router.urls, namespace='router')),
    url(r'^api-auth/', include('rest_framework.urls', 
namespace='rest_framework'))
]

我想念什么？我收到未提供的app_name，将其添加到此文件后无济于事。有没有办法将app_name放入路由器？

Answer 1

结果很难找到确切的使用基名的方法，我没有在反向添加“ -list”。应该是以下内容，希望对其他人有所帮助：

reverse('router:compressors-list')

DRF路由器名称空间问题
