Django is saying that the url doesn't match itself

Question

from django.urls import path
from .views import index

urlpatterns = [

    path('', index),
    path('/join', index),
    path('/create', index)
    
]

Page not found (404)
Request Method: GET
Request URL:    http://127.0.0.1:8000/join
Using the URLconf defined in music_controller.urls, Django tried these URL patterns, in this order:

admin/
api/
/join
/create
The current path, join, didn’t match any of these. "

someone please tell me how join doesn't match join? thank you.

Answer 1

You should not prepend the path with a leading slash, so:

urlpatterns = [
    # …,
    path('join/', join),
    # …
]

not:

urlpatterns = [
    # …,
    path('/join', join),
    # …
]

you probably also want to add an trailing slash, although not required, Django's paths typically end with a trailing slash, and if no path matches, and the APPEND_SLASH setting ^[Django-doc] is set to True, it will try to redirect to a path with a trailing slash.
