NoReverseMatch error happened while redirecting to another url from views.py in django

I am trying to redirect user after the signup is done and getting the below error.

Reverse for 'verificationsent' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []


urls.py --

urlpatterns = [
url(r'^ciasadmin/', admin.site.urls),
url("^$", views.homepage, name="home"),
url(r'^account/', include('accounts.urls')),
]


accounts/urls.py --

from django.conf.urls import url
from . import views


urlpatterns = [
url(r"^signup/$", views.signup, name="account_signup"),
url(r'^verificationsent/$', views.verificationsent, name='account_verificationsent'),
url(r'^activate/(?P<uidb64>[0-9A-Za-z_\-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',views.activate, name='activate'),
]


views.py --

return redirect('verificationsent')

I have followed the solutions from the below SO references but didn't work.

Redirect with parameters. NoReverseMatch at /test/

Django NoReverseMatch in form redirect

Any help is highly appreciated. Thanks in advance.

You should not use direct url reference statements as per best practice. Always reverse the urls

return redirect(reverse('account_verificationsent'))

If you have a namespace for your app then you have to use that in reverse also.
