Here we can see register function is registered
Using the URLconf defined in tarunmahajan.urls, Django tried these URL patterns, in this order:

  1. admin/
  3. old
  4. about
  5. hello
  6. register

Well I used return render(request, 'register.html') instead of return redirect('register') so it's solved my problem temporary but I'm keep looking on it. Even after registering function properly in urls.py

Some interesting conversation I found mention below.

  1. NoReverseMatch error
  2. NoReverseMatch at /blog/redirect2
  3. Why am I getting no reverse match error in django 3.2?

Solution: Well I missed to mention function name in urlpatterns arrays at urls.py from django.urls import path from . import views

Previous code ``` urlpatterns = [ path('', views.index), path('old', views.view), path('about', views.about), path('hello', views.say_hello), path('register', views.register), path('login', views.login), path('logout', views.logout) ] ```
Changed code ``` urlpatterns = [ path('', views.index), path('old', views.view, name='old'), path('about', views.about, name='about'), path('hello', views.say_hello, name='say_hello'), path('register', views.register, name='register'), path('login', views.login,name='login'), path('logout', views.logout, name='logout') ] ```
