如何更改路由器 URL 前缀以在 Django Rest Framework (DRF) 中传递双重查找字段

Question

我想为特殊博客 post 的评论设置 URL。所以我需要那个博客的ID，但我不知道如何更改前缀。

url.py

from django.urls import path, include
from rest_framework.routers import SimpleRouter

from .views import BlogViewSet, CommentViewSet

router = SimpleRouter()
router.register('blog', BlogViewSet, basename='blog')
router.register('blog/<int:id>/comments', CommentViewSet, basename='comments')
urlpatterns = [
   path('', include(router.urls)),

]

Answer 1

我们可以使用 drf-nested-routers 包来做到这一点。 drf-nested-router

from django.urls import path, include
from rest_framework.routers import SimpleRouter
from rest_framework_nested import routers

from .views import BlogViewSet, CommentViewSet


router = SimpleRouter()
router.register('blog', BlogViewSet, basename='blog')
domains_router = routers.NestedSimpleRouter(router, r'blog', lookup='blog')
domains_router.register(r'comments', CommentViewSet, basename='comments')
urlpatterns = [
    path('', include(router.urls)),
    path('', include(domains_router.urls)),

]
