name 'settings' is not defined

Question

I add urls in these lines for media and image output to the template. But I meet such a bug. name 'settings' is not defined How do I fix it?

urlpatterns =+ patterns('',
    url(r'^static/(?P<path>.*)$', 'django.views.static.serve', {
        'document_root': settings.STATIC_ROOT,
    }),
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {
        'document_root': settings.MEDIA_ROOT,
    }),

Answer 1

Add

from django.conf import settings

to the top of your file. And change the operator used in urlpatterns variable assignment.

urlpatterns =+ patterns('',

should be

urlpatterns += patterns('',

There is no =+ operator in python.

EDIT:

From the urlpattern posted in comment, I see that there is no other urlpattern and the urlpattern should be as follows without the + sign.

urlpatterns = patterns('',
    url(r'^static/(?P<path>.*)$', 'django.views.static.serve', { 'document_root': settings.STATIC_ROOT, }),
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve', { 'document_root': settings.MEDIA_ROOT, }),
)
