Django 2.0 path error ?: (2_0.W001) has a route that contains '(?P<', begins with a '^', or ends with a '$'
The new path() syntax in Django 2.0 does not use regular expressions. You want something like:
path('<int:album_id>/', views.detail, name='detail'),If you want to use a regular expression, you can use re_path().
re_path(r'^(?P<album_id>[0-9])/$', views.detail, name='detail'),The old url() still works and is now an alias to re_path, but it is likely to be deprecated in future.
url(r'^(?P<album_id>[0-9])/$', views.detail, name='detail'),
Just to add to what @alasdair mentioned, I added re_path as part of the include and it works fine. Here is an example
Add re_path to your import (for django 2.0)
from django.urls import path, re_pathurlpatterns = [ path('admin/', admin.site.urls), re_path(r'^$', home, name='home'),]
Instead of using 're_path' you can also use ''(empty string) as the first argument of your path(). I have used it and it worked for me.
urlpatterns = [ path('admin/', admin.site.urls), path('',views.index,name='index'),]
