Instructions on integrating Merlin extensions into Horizon

Although the repo contains directories meant to be used as Django apps (with templates, static files, urls & views), the whole project is not meant to be run as a standalone Django web-application (with its own settings.py etc). Instead, it should be embedded into running Horizon instance. To do so you should perform the following steps:

1. The easiest way to always use the latest version of Merlin is by using symlinks. Identify the directory where openstack_dashboard and horizon reside. Let's assume this is /usr/lib/python2.7/site-packages and merlin repo is located at /home/user/dev/merlin. Then run the following commands

# for main Merlin sources
ln -s /home/user/dev/merlin/merlin /usr/lib/python2.7/site-packages/merlin
# for files of the Merlin's Mistral extension
ln -s /home/user/dev/merlin/extensions/mistral /usr/lib/python2.7/site-packages/mistral

1. Next thing to do is add panel with Mistral Workbook builder (a Merlin extension) into Horizon. To do it, copy the pluggable config for the Mistral panel:

cp /home/user/dev/merlin/extensions/enabled/_50_add_mistral_panel.py /usr/lib/python2.7/site-packages/openstack_dashboard/enabled/

1. Restart Horizon web-server. According to the default values in _50_add_mistral_panel.py you would be able to Mistral panel inside the Project dashboard, Orchestration panel group.
