Django Debug Toolbar shows at root URL, but not in app URL -

i have new project , i'm trying set django debug toolbar. first tried quick setup, involves adding 'debug_toolbar' list of installed apps. this, debug toolbar showed when went root url, did not work app urls/views. should not presently, root url not linked view, showing django error page.

since quick start didn't work, went explicit setup. updated settings file:

debug_toolbar_patch_settings = false  middleware_classes = (     'django.contrib.sessions.middleware.sessionmiddleware',     'django.middleware.common.commonmiddleware',     'django.middleware.csrf.csrfviewmiddleware',     'django.contrib.auth.middleware.authenticationmiddleware',     'django.contrib.auth.middleware.sessionauthenticationmiddleware',     'django.contrib.messages.middleware.messagemiddleware',     'django.middleware.clickjacking.xframeoptionsmiddleware',     'debug_toolbar.middleware.debugtoolbarmiddleware', ) 

and updated project-level urls.py:

if settings.debug: # make sure toolbar above ?ckeditor , feincms     import debug_toolbar     urlpatterns += patterns('',         url(r'^__debug__/', include(debug_toolbar.urls)),     ) 

but doesn't show anywhere.

in app view, i've added {% debug %} template. template debug output seem indicate debug toolbar middleware has been loaded:

 'debug_toolbar': <module 'debug_toolbar' '/home/joseph/.virtualenvs/myproject/local/lib/python2.7/site-packages/debug_toolbar/__init__.pyc'>,  'debug_toolbar.collections': none,  'debug_toolbar.compat': <module 'debug_toolbar.compat' '/home/joseph/.virtualenvs/myproject/local/lib/python2.7/site-packages/debug_toolbar/compat.pyc'>,  'debug_toolbar.django': none,  'debug_toolbar.importlib': none,  'debug_toolbar.middleware': <module 'debug_toolbar.middleware' '/home/joseph/.virtualenvs/myproject/local/lib/python2.7/site-packages/debug_toolbar/middleware.pyc'>, 

i'm not sure why isn't working. django version 1.8 , debug toolbar version 1.3.2.
