update_metadata for flavors and images shows blank. static basePath not set correctly.

[Ross Krumbeck]

Currently using OpenStack Kilo on CentOS 7. Issue is with:

openstack-dashboard-2015.1.0-7.el7.noarch
/usr/share/openstack-dashboard/static/angular/widget.module.js

When using the update_metadata feature in horizon in the flavors and images section, the meta data table is not displayed. Have also seen this cause problems when using heat.

The basePath in the javascript is not being set correctly and resulting in a redirect loop:

[Tue Jul 21 00:14:22.097739 2015] [core:error] [pid 14453] (36)File name too long: [client ] AH00036: access to /dashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboardauth/login/ failed (filesystem path '/var/www/html/dashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboarddashboardauth')

I was able to fix by modifying the widget.module.js file

$ diff -u /usr/share/openstack-dashboard/static/angular/widget.module.js.orig /usr/share/openstack-dashboard/static/angular/widget.module.js

Ideally this file should not need to be modified and should be generated using WEBROOT in local_settings, alternatively documentation should be updated if this file must be modified by hand.

An alternate work around is to add an additional Apache alias in the vhost configuration:

  Alias /dashboard/static "/usr/share/openstack-dashboard/static"
  Alias /static "/usr/share/openstack-dashboard/static"

I've started backporting the Liberty fix https://review.openstack.org/#/c/181095/58 into Kilo: https://review.openstack.org/#/c/209108/

[Timur Sufiev (tsufiev-x)]

The backport is ready and waiting to be merged.

    Backport the WEBROOT fixes for JS and CSS into Kilo

    This commit includes changes relevant to commits
    https://review.openstack.org/181095 and
    https://review.openstack.org/#/c/201769/. But rather than precisely
    backporting the above commits (which is impossible due to different
    code structure), a 'symptomatic treatment' approach is used: we fix
    every problem which is related to being ignorant to WEBROOT setting in
    Kilo. Among the places being fixed are:

    * edit metadata widget
    * launch instance NG (both templates and service calls).
