视图集中的反向（事物）django休息框架答案

【问题标题】：reverse(thing) django rest framework in a viewset视图集中的反向（事物）django休息框架

【问题描述】：

主要问题是：什么是其余框架 ViewSet 友好的方式来制作反向路由？

在 django cookiecutter 站点中，我有 api_router.py

router.register(r"users", UserViewSet)
router.register(r"userprofile", UserProfileViewSet, basename="userprofile")
router.register(r"student", StudentViewSet)
    
urlpatterns = router.urls
app_name = "api"

print(f"we have routes")
for route in router.urls:
    print(route)
print(f"{reverse('student-list') = }")

哪个错误说反向找不到学生列表

学生 model.py 有一个符合标准的 StudentViewSet

class StudentViewSet(
    RetrieveModelMixin,
    CreateModelMixin,
    ListModelMixin,
    UpdateModelMixin,
    GenericViewSet,
):

所以它应该有创建学生列表所需的东西

该打印语句的输出显示学生列表

athenaeum_local_django    | <URLPattern '^student/$' [name='student-list']>
athenaeum_local_django    | <URLPattern '^student\.(?P<format>[a-z0-9]+)/?$' [name='student-list']>
athenaeum_local_django    | <URLPattern '^student/(?P<userprofile__user__username>[^/.]+)/$' [name='student-detail']>
athenaeum_local_django    | <URLPattern '^student/(?P<userprofile__user__username>[^/.]+)\.(?P<format>[a-z0-9]+)/?$' [name='student-detail']>

错误结束如下：

【问题讨论】：

既然你有一个app_name，你将不得不反向使用它，所以：reverse('api:student-list')
说真的：设置 ^ 作为答案。我现在正在处理其他错误。 :)

【解决方案1】：

既然你已经设置了app_name，你将不得不在reverse中使用它，所以：

reverse('api:student-list')
