Unable to manually compress js and css

[Marcin Zbik]

Unable to compress js and css after cleaning /usr/share/openstack-dashboard/static (needed to do this when changing default path from /horizon to /) on Mitaka and Ubuntu 16.04

Steps to reproduce:
1. Install openstack-dashboard
2. clean /usr/share/openstack-dashboard/static directory
3. Do /usr/share/openstack-dashboard/manage.py collectstatic
     It will collect 1285 static files
4. Then try to compress and it will fail:

# /usr/share/openstack-dashboard/manage.py compress
Found 'compress' tags in:
        /usr/share/openstack-dashboard/openstack_dashboard/templates/horizon/_conf.html
        /usr/share/openstack-dashboard/openstack_dashboard/templates/_stylesheets.html
        /usr/share/openstack-dashboard/openstack_dashboard/templates/horizon/_scripts.html
Compressing... CommandError: An error occurred during rendering /usr/share/openstack-dashboard/openstack_dashboard/templates/_stylesheets.html: Couldn't find anything to import: /dashboard/scss/horizon.scss

Search path:

on line 1 of u'string:0c838b58954113a8:\n // My Themes\n@import "/themes/default/variables";\n\n// Horizon\n@import "/dashboard/scss/horizon.'

Even disabling ubuntu theme does not help.

Status changed to 'Confirmed' because the bug affects multiple users.

Hello Marcin, What version of python-django-compressor do you have installed?

[Marcin Zbik (zbikmarc+launchpad)]

Hello Corey,
I think its latest one from repository: 2.0-1ubuntu1 (this version is installed)

[Corey Bryant (corey.bryant)]

Are you deleting all of the contents from /usr/share/openstack-dashboard/static/ prior to collecting/compressing static assets?

If so, I don't think this is something that you should be doing, since part of the package install copies the contents of openstack_dashboard/ to /usr/share/openstack-dashboard.

If you're deleting all of the contents of the static directory, then you'll still be missing files even if you re-collect/re-compress static assets. In particular the app and dashboard directories. For reference, here is upstream's 9.0.0 static contents:

Hello Marcin, Hopefully you've made some progress to work around this. I've gone ahead and marked this bug as invalid based on my prior comment.

[Marcin Zbik (zbikmarc+launchpad)]

Hi Corey,
I dropped that as lower priority than other my task, its why I did not respond.

Answering your question, yes Im deleting content of that directory, because it was working with Liberty. It does not without ;)

I will reinwestigate it later and in case of futher problems will reopen this bug.
