A network operation can fail because of different reasons - yet in many places just one error message is provided. Combined with too broad exception clause, and incorrect assumptions on the reasons of failure (e.g. Neutron service being unavailable causes all other sorts of errors like inability to Allocate IP or Associate it) this leads to multiple errors when just one would suffice. The fix aims to provide sensible error messages in case the network service is down. This includes returning only unique messages in a single response.

Horizon (OpenStack Dashboard)
Horizon is a Django-based project aimed at providing a complete
OpenStack Dashboard along with an extensible framework for building new
dashboards from reusable components. The
openstack_dashboard
module is a reference implementation of
a Django site that uses the horizon
app to provide
web-based interactions with the various OpenStack projects.

Getting Started
For local development, first create a virtualenv for the project. In
the tools
directory there is a script to create one for
you:
$ python tools/install_venv.py
Alternatively, the run_tests.sh
script will also install
the environment for you and then run the full test suite to verify
everything is installed and functioning correctly.
Now that the virtualenv is created, you need to configure your local
environment. To do this, create a local_settings.py
file in
the openstack_dashboard/local/
directory. There is a
local_settings.py.example
file there that may be used as a
template.
If all is well you should able to run the development server locally:
$ tools/with_venv.sh ./manage.py runserver
or, as a shortcut:
$ ./run_tests.sh --runserver
Setting Up OpenStack
The recommended tool for installing and configuring the core OpenStack components is Devstack. Refer to their documentation for getting Nova, Keystone, Glance, etc. up and running.
Note
The minimum required set of OpenStack services running includes the following:
- Nova (compute, api, scheduler, network, and volume services)
- Glance
- Keystone
Optional support is provided for Swift.
Development
For development, start with the getting started instructions above. Once you have a working virtualenv and all the necessary packages, read on.
If dependencies are added to either horizon
or
openstack_dashboard
, they should be added to
requirements.txt
.
The run_tests.sh
script invokes tests and analyses on
both of these components in its process, and it is what Jenkins uses to
verify the stability of the project. If run before an environment is set
up, it will ask if you wish to install one.
To run the unit tests:
$ ./run_tests.sh
