Gabriel Hurley ea96bb3a22 Adds docs for settings/configuration.
In addition to thoroughly documenting the settings and config
options for Horizon/OpenStack Dashboard, this clarifies some
misconceptions around how to enable Object Storage/Swift
and Netowrking/Quantum in the OpenStack Dashboard.

Fixes bug 1064412. DocImpact.

Customizing Horizon
===================
Changing the Site Title
=======================
The OpenStack Dashboard Site Title branding (i.e. "**OpenStack** Dashboard")
can be overwritten by adding the attribute ``SITE_BRANDING``
to ``local_settings.py`` with the value being the desired name.
The file ``local_settings.py`` can be found at the Horizon directory path of
``horizon/openstack-dashboard/local/local_settings.py``.
Changing the Logo
=================
The OpenStack Logo is pulled in through ``style.css``::
#splash .modal {
background: #fff url(../images/logo.png) no-repeat center 35px;
h1.brand a {
background: url(../images/logo.png) top left no-repeat;
To override the OpenStack Logo image, replace the image at the directory path
``horizon/openstack-dashboard/dashboard/static/dashboard/images/logo.png``.
The dimensions should be ``width: 108px, height: 121px``.
Modifying Existing Dashboards and Panels
========================================
If you wish to alter dashboards or panels which are not part of your codebase,
you can specify a custom python module which will be loaded after the entire
Horizon site has been initialized, but prior to the URLconf construction.
This allows for common site-customization requirements such as:
* Registering or unregistering panels from an existing dashboard.
* Changing the names of dashboards and panels.
* Re-ordering panels within a dashboard or panel group.
To specify the python module containing your modifications, add the key
``customization_module`` to your ``settings.HORIZON_CONFIG`` dictionary.
The value should be a string containing the path to your module in dotted
python path notation. Example::
HORIZON_CONFIG = {
"customization_module": "my_project.overrides"
}
You can do essentially anything you like in the customization module. For
example, you could change the name of a panel::
from django.utils.translation import ugettext_lazy as _
import horizon
# Rename "User Settings" to "User Options"
settings = horizon.get_dashboard("settings")
user_panel = settings.get_panel("user")
user_panel.name = _("User Options")
Or get the instances panel::
projects_dashboard = horizon.get_dashboard("project")
instances_panel = projects_dashboard.get_panel("instances")
And limit access to users with the Keystone Admin role::
permissions = list(getattr(instances_panel, 'permissions', []))
permissions.append('openstack.roles.admin')
instances_panel.permissions = tuple(permissions)
Or just remove it entirely::
projects_dashboard.unregister(instances_panel.__class__)
.. NOTE::
``my_project.overrides`` needs to be importable by the python process running
Horizon.
If your module is not installed as a system-wide python package,
you can either make it installable (e.g., with a setup.py)
or you can adjust the python path used by your WSGI server to include its location.
Probably the easiest way is to add a ``python-path`` argument to
the ``WSGIDaemonProcess`` line in Apache's Horizon config.
Assuming your ``my_project`` module lives in ``/opt/python/my_project``,
you'd make it look like the following::
WSGIDaemonProcess [... existing options ...] python-path=/opt/python
Button Icons
============
Horizon provides hooks for customizing the look and feel of each class of
button on the site. The following classes are used to identify each type of
button:
* Generic Classes
* btn-search
* btn-delete
* btn-upload
* btn-download
* btn-create
* btn-edit
* btn-list
* btn-copy
* btn-camera
* btn-stats
* btn-enable
* btn-disable
* Floating IP-specific Classes
* btn-allocate
* btn-release
* btn-associate
* btn-disassociate
* Instance-specific Classes
* btn-launch
* btn-terminate
* btn-reboot
* btn-pause
* btn-suspend
* btn-console
* btn-log
* Volume-specific classes
* btn-detach
Additionally, the site-wide default button classes can be configured by
setting ``ACTION_CSS_CLASSES`` to a tuple of the classes you wish to appear
on all action buttons in your ``local_settings.py`` file.
