Error with the content of the Horizon dashboard tutorial at http://docs.openstack.org/developer/horizon/topics/table_actions.html#adding-the-url

[Varsha]

This tutorial specifies the following changes to be made to urls.py file:

from django.conf.urls import url

from openstack_dashboard.dashboards.mydashboard.mypanel import views

urlpatterns = [,
    url(r'^$',
        views.IndexView.as_view(), name='index'),
    url(r'^(?P<instance_id>[^/]+)/create_snapshot/$',
        views.CreateSnapshotView.as_view(),
        name='create_snapshot'),
]

After this change has been made, and after I restart the httpd I get an error in the horizon_error.log as posted below:

__import__(name)
[:error] [pid 11724] [remote 172.22.225.42:0] File "/usr/share/openstack-dashboard/openstack_dashboard/wsgi/../../openstack_dashboard/dashboards/mydashboard/mypanel/urls.py", line 6
[:error] [pid 11724] [remote 172.22.225.42:0] urlpatterns = [,
[:error] [pid 11724] [remote 172.22.225.42:0] ^
[:error] [pid 11724] [remote 172.22.225.42:0] SyntaxError: invalid syntax

To fix this issue, we need to remove the comma next to the opening square bracket in urlpatterns = [,
The resulting code should look like:

urlpatterns = [
    url(r'^$',
        views.IndexView.as_view(), name='index'),
    url(r'^(?P<instance_id>[^/]+)/create_snapshot/$',
        views.CreateSnapshotView.as_view(),
        name='create_snapshot'),
]

This is already fixed in master branch. For more information please refer [1]. So marking it as invalid.
