Django rest框架问题

Question

下面是我的代码：

from rest_framework import routers
from rest_framework.routers import DefaultRouter

from .api import ListViewSet, CardViewSet

router = DefaultRouter()
router.register(r'lists', ListViewSet,'lists')
router.register(r'cards', CardViewSet, 'cards')

urlpatterns = router.urls

但是当我运行服务器时，我得到了这个错误：

Page not found (404) Request Method:
GET Request URL: http://localhost:8000/scrumboard/cards Using the URLconf defined in djangularApp.urls, Django tried these URL patterns, in this order:

^admin/ ^$ ^scrumboard ^lists/$ [name='lists-list'] ^scrumboard
^lists\.(?P<format>[a-z0-9]+)/?$ [name='lists-list'] ^scrumboard
^lists/(?P<pk>[^/.]+)/$ [name='lists-detail'] ^scrumboard
^lists/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)/?$ [name='lists-detail']
^scrumboard ^cards/$ [name='cards-list'] ^scrumboard
^cards\.(?P<format>[a-z0-9]+)/?$ [name='cards-list'] ^scrumboard
^cards/(?P<pk>[^/.]+)/$ [name='cards-detail'] ^scrumboard
^cards/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)/?$ [name='cards-detail']
^scrumboard ^$ [name='api-root'] ^scrumboard
^\.(?P<format>[a-z0-9]+)/?$ [name='api-root']
The current path, scrumboard/cards, didn't match any of these.

您之所以看到这个错误，是因为您的Django设置文件中有DEBUG = True。将其更改为False，Django将显示一个标准的404页面。

Answer 1

看起来您忘记在scrumboard url后面添加一个/，很可能是在包含路由器的url的地方。这是可见的，因为^scrumboard ^cards/$应该是^scrumboard/ ^cards/$，以匹配您期望的url。

Answer 2

您似乎还没有在您的project/urls.py中注册url

path('api/', include((router.urls), namespace='api')),

这意味着路径将以/api/cards开头

或用于/scrumboard

path('scrumboard/', include((router.urls), namespace='scrumboard')),

然后，您可以使用/scrumboard/cards
