============================================

    :target: https://governance.openstack.org/tc/reference/tags/index.html


How to use with Horizon on server:
----------------------------------

Use pip to install the package on the server running Horizon. Then either copy
or link the files in trove_dashboard/enabled to
openstack_dashboard/local/enabled. This step will cause the Horizon service to
pick up the trove plugin when it starts.

How to use with devstack:
-------------------------

Add the following to your devstack ``local.conf`` file::

    enable_plugin trove-dashboard https://opendev.org/openstack/trove-dashboard

Here is a full example of devstack ``local.conf`` file that includes the trove plugin::

    [[local|localrc]]
    RECLONE=False
    HOST_IP=<your-host-ip-here>

    enable_plugin trove https://opendev.org/openstack/trove
    enable_plugin trove-dashboard https://opendev.org/openstack/trove-dashboard

To run unit tests:
------------------
::

    ./run_tests.sh

Editing Code
------------

Apache
~~~~~~

Make a change to trove-dashboard then goto to the horizon directory and
compress the code with django and then restart apache.::

    # rsync code to /opt/stack/trove-dashboard
    # copy or link files from trove-dashboard/enabled/* to horizon/openstack_dashboard/local/enabled/
    cd /opt/stack/horizon
    python manage.py compress
    python manage.py collectstatic --noinput
    sudo service apache2 restart


Django
~~~~~~

You can also speed up development time using the django test server instead of
apache.::

    /opt/stack/horizon/run_tests.sh --runserver

If you set COMPRESS_ENABLED and COMPRESS_OFFLINE to False in local_settings.py
that allows you to bypass the compress and collectstatic as well.


Settings
~~~~~~~~

The use of a cross-process cache such as Memcached is required.

Install Memcached itself and a Memcached binding such as python-memcached.

For a single horizon instance use the CACHES setting like the example below.::

    CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
            'LOCATION': '127.0.0.1:11211',
        },
    }

For multiple horizon instances behind a load balancer configure each instance
to use the same cache like the example below.::

    CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
            'LOCATION': [u'10.2.100.133:11211', u'10.2.100.134:11211'']
        },
    }


NOTE:
=====

As of the Mitaka release, the dashboard for trove is now maintained outside of
the Horizon codebase, in this repository.
