[Openstack] horizon customization_module example???
Can someone elaborate on how to use the customization_module setting in local_settings.py? Im running openstack-dashboard Version: 2012.2.1-0ubuntu1~cloud0 on Ubuntu 12.04 LTS. I read the documentation here - http://docs.openstack.org/developer/horizon/topics/customizing.html but several things are still unclear to me, even for a simple mod such as removing and/or renaming some panels. I want to just make a few modifications to the standard dashboard and panel, I don't want to write a whole new dashboard or write entirely new panels. I just want to eliminate some of the existing ones (as a start). For example, say I want to eliminate the volumes and instances panels from the project dashboards. I'd prefer to NOT have to modifying the original system modules deep down in /usr/share/pyshared/horizon/dashboards/nova/dashboard.py. I hope that's not the answer. The documentation seems to indicate that this could be done with the customization_module, but I can't figure out where it goes or what the structure would look like. Questions: - If I name the customization_module as my_dashboard.overrides - where does the overrides file need to be created (i.e. what directory - full path) ? - Does it require other files to be present in that directory also such as the __init__.py or models.py like a complete dashboard would? I think once I can figure out where to put my custom mods without making horizon barf all over itself, I can make my changes, but getting started is proving difficult. thanks, Wyllys ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

So your my_dashboard module needs to be on your python path somehow. Probably the easiest way is to add a python-path argument to the WSGIDaemonProcess line in Apache's Horizon config. I'm not sure where this lives exactly for the ubuntu package (should be somewhere under /etc/apache2/). Assuming your my_dashboard module lives in /opt/python/my_dashboard, you'd make it look like the following: WSGIDaemonProcess [... existing options ...] python-path=/opt/python Alternatively you can make your module an installable python package and install it system-wide (e.g., create a setup.py). - Does it require other files to be present in that directory also such as the __init__.py or models.py like a complete dashboard would? It will need a __init__.py but should be fine without a models.py. I'll see about getting this info added to the docs.

Thanks! Any hints on how to remove some of the default Nova panels from the dashboard using the customization_module?

Something like:
import horizon
nova = horizon.get_dashboard('nova')
nova.unregister(nova.get_panel('instances').__class__)
Substitute projects for nova in Grizzly.
You can also limit a panel to certain keystone roles with an
openstack.roles.role permission:
nova.get_panel('instances').permissions = ('openstack.roles.admin',)
or, more robustly:
instances = nova.get_panel('instances')
permissions = list(getattr(instances, 'permissions', []))
permissions.append('openstack.roles.admin')
instances.permissions = tuple(permissions)
Cheers,
Kieran

my_dashboard.overrides needs to be importable by the process running
Horizon. So your my_dashboard module needs to be on your python path
somehow. Probably the easiest way is to add a python-path argument to
the WSGIDaemonProcess line in Apache's Horizon config. I'm not sure

Assuming your my_dashboard module lives in /opt/python/my_dashboard,
you'd make it look like the following:
WSGIDaemonProcess [... existing options ...] python-path=/opt/python
Alternatively you can make your module an installable python package
and install it system-wide (e.g., create a setup.py).

It will need a __init__.py but should be fine without a models.py.
