OpenStack Dashboard (Horizon)

The reference implementation for Building on Horizon doesn't works

Asked by Toby Harris

Hi,

I downloaded the zip archive for horizon demo from https://github.com/gabrielhurley/horizon_demo. When I run the command ./run_tests.sh --runserver to start the dev server I get the below error.

Any idea on how to fix this error? I just unzipped the archive and ran the above command. Do I need to modify any settings?

Phew.
That code hasn't been touched for about two years now, and the OpenStack Dashboard is under very active development. I'd take a more recent version from a distribution or from github.com/openstack/horizon

Please also note, this section here is deprecated in favour of ask.openstack.org.

Hi Matthias,

Thanks for your reply. I shifted from Windows to Ubuntu and now I don't see this error. However i get a different error now when trying to start the dev server. I am using Ubuntu on a VM created using VMWARE player.

File "manage.py", line 18, in <module>
    from django.core.management import execute_manager
ImportError: No module named core.management

I have verified that Django is installed in my virtual environment. Could you help suggest any solution?

Thanks
Toby

Hi,

Just to further update. The problem got resolved after changing the manage.py from #!/usr/bin/env python to #!/usr/bin/env python2.

However now I am getting the below error.

ImportError: Could not import settings 'openstack_dashboard.settings' (Is it on sys.path?): No module named cinderClient.

Any idea why I am getting this error?

Regards
Toby

cinderClient with capital 'C'? Honestly?

It seems you're trying to learn OpenStack and esp. Horizon.
Please refer to the official docs http://docs.openstack.org

When choosing a distribution, all requirements (which are clearly not satisfied right now on your install) will be fulfilled.

Every distribution should have one python installed (thus, solvable via /usr/bin/env python.

If you're using ubuntu, apt-get install openstack-dashboard should install you horizon and all its dependencies.

I definitely think we should create a new tutorial. This old one is really, really hindering: http://docs.openstack.org/developer/horizon/topics/tutorial.html.
