Any /polls Url Always Call Index() Function In Views.py

polls/urls/py from django.conf.urls import url from . import views urlpatterns = [ url('', views.index, name='index'), url('/', views.detail, name='detai

Solution 1:

Firstly, it's really important to make sure that you are following the tutorial that matches your version of Django. Here are the links for Django 2.0 and Django 1.11.

You are getting the unexpected behaviour because you are mixing the old url and new path syntax. If you are using Django 2.0, change the import and update your URL patterns:

from django.urls import path

urlpatterns = [

    path('', views.index, name='index'),
    path('<int:question_id>/', views.detail, name='detail'),

    # ex: /polls/5/results/
    path('<int:question_id>/results/', views.results, name='results'),
    # ex: /polls/5/vote/
    path('<int:question_id>/vote/', views.vote, name='vote'),

]

If you are using an earlier version of Django, you need to use regexes instead. For example, the Django 1.11 tutorial gets you to write:

from django.conf.urls import url

urlpatterns = [
    # ex: /polls/
    url(r'^$', views.index, name='index'),
    # ex: /polls/5/
    url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),
    # ex: /polls/5/results/
    url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),
    # ex: /polls/5/vote/
    url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'),
]

Solution 2:

Which version of Django is this? Your url patterns look like a mixture of 2.0 and older routing.

Your empty url pattern would probably match anything so not another route ever gets called.

For Django 2.0 + do what @Alasdair suggest above for older Django version something like below:

urlpatterns = [
    url(r'^$', views.index, name='index'),
]
