python - Django logout makes trouble with the error : Reverse for 'logout' with arguments '()' and keyword arguments '{}' not found -

my error below :

reverse 'logout' arguments '()' , keyword arguments '{}' not found

my 'urls.py' below :

urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^$',homeview.as_view(), name='home'), url(r'^about/$',aboutview.as_view(), name='about'), url(r'^login/$', views.loginview, name='login'), url(r'^inquiry/$',inquiryview.as_view(), name='inquiry'), url(r'^service_terms/$',servicetermsview.as_view(), name='service_terms'), url(r'^privacy_terms/$',privacytermsview.as_view(), name='privacy_terms'), url(r'^logout/$,', views.logoutview, name='logout'), ] 

my 'views.py' below:

@login_required def logoutview(request): if request.method == 'post':     logout(request)     print('logout done') return render(request, 'about.html') 

my code logging out in 'navbar.html' below:

<li><a href="{% url 'logout' %}">logout</a></li> 

i totally not understand i'm missing. there i'm doing wrong?

you have comma in regex shouldn't there. replace

url(r'^logout/$,', views.logoutview, name='logout'), 

with

url(r'^logout/$', views.logoutview, name='logout'),
