Django 1.9 url include AttributeError 'str' object has no attribute 'regex'

Question

I recently upgraded from Django 1.7 to 1.9, and having some trouble converting the urls with includes.

I get the error message: AttributeError: 'str' object has no attribute 'regex'

urls.py files below:

myapp/urls.py:

from django.conf.urls import url

from myapp.views import IndexView

#app_name = 'myapp'

urlpatterns = [
  url(r'^$', IndexView.as_view(), name='index'),
]

mysite/urls.py:

from django.conf.urls import url, include

urlpatterns = [
  url(r'^myapp/', include('myapp.urls')),

  # Have also tried the following combinations
  #url(r'^myapp/', include('myapp.urls', 'myapp')),
  #url(r'^myapp/', include('myapp.urls'), name='myapp'),

  # This one works
  url(r'^admin/', admin.site.urls),
]

Full stack trace:

    regex_pattern = pattern.regex.pattern
AttributeError: 'str' object has no attribute 'regex'

The stack trace above came from running on the command line, but I do get the same error trying to launch the test server. — Tal Yardeni

Shouldn't you import include as well here from django.conf.urls import url, include ? I mean instead of having import, you should have include, I think.

I had a block of code commented out as a string in myapp/urls.py which was causing the issue:

from django.conf.urls import url

from myapp.views import IndexView

#app_name = 'myapp'

urlpatterns = [
  url(r'^$', IndexView.as_view(), name='index'),

  '''

  ...some old code from the Django 1.7.6 config

  '''
]

Django is attempting to read the string as a url object, which was causing the error.

Removing the string fixed the problem.

instead

from django.conf.urls import url, import
