How do I set up my Django urlpatterns within my app (not project)
Let's say I've got the classic "School" app within my Django project. My school/models.py contains models for both student and course. All my project files live within a directory I named config. How do I write an include statement(s) within config/urls.py that references two separate endpoints within school/urls.py? And then what do I put in schools/urls.py? For example, if I were trying to define an endpoint just for students, in config/urls.py I would do something like this: from django.urls import path, include urlpatterns = [ ... path("students/", include("school.urls"), name="students"), ... ] And then in school/urls.py I would do something like this: from django.urls import path from peakbagger.views import StudentCreateView, StudentDetailView, StudentListView, StudentUpdateView, StudentDeleteView urlpatterns = [ # ... path("", StudentListView.as_view(), name="student-list"), path("add/", StudentCreateView.as_view(), name="student-add"), path("<int:pk>/", StudentDetailView.as_view(), name="student-detail"), path("<int:pk>/update/", StudentUpdateView.as_view(), name="student-update"), path("<int:pk>/delete/", StudentDeleteView.as_view(), name="student-delete"), ] But how do I do I add another urlpattern to config/urls.py along the lines of something like this? The include statement needs some additional info/parameters, no? from django.urls import path, include urlpatterns = [ ... path("students/", include("school.urls"), name="students"), path("courses/", include("school.urls"), name="courses"), ... ] And then what happens inside of school/urls.py? I'm open to suggestions, and definitely am a neophyte when it comes to the Django philosophy. … -

Add field to DRF's exceptions.PermissionDenied
