OE Layer Index web interface

This is a small Django-based web application that provides a way to manage an index of OpenEmbedded metadata layers for use on top of OE-Core.

Setup

In order to make use of this application you will need:

• Django 1.4.x - tested with 1.4.1-1.4.10; newer versions may work, but the application has not been tested with 1.5 or newer.
• For production usage, a web server set up to host Django applications (not needed for local-only testing)
• A database supported by Django (SQLite, MySQL, etc.). Django takes care of creating the database itself, you just need to ensure that the database server (if not using SQLite) is configured and running.
• The following third-party Django modules (tested versions listed):
  • django-south (0.8.4)
  • django-registration (1.0)
  • django-reversion (1.7.1)
  • django-reversion-compare (0.3.5)
  • django-simple-captcha (0.4.1)
  • django-nvd3 (0.6.0)
  • djangorestframework (2.3.14)
  • django-cors-headers (0.12)
• On the machine that will run the backend update script (which does not have to be the same machine as the web server, however it does still have to have Django installed, have the same or similar configuration in settings.py and have access to the database used by the web application):
  • Python 2.7.3
  • GitPython (python-git) version 0.3.1 or later

Setup instructions:

1. Edit settings.py to specify a database, EMAIL_HOST, SECRET_KEY and other settings specific to your installation. Ensure you set LAYER_FETCH_DIR to an absolute path to a location with sufficient space for fetching layer repositories.

2. Run the following commands within the layerindex-web directory to initialise the database:

   python manage.py syncdb python manage.py migrate

   You should answer "yes" when asked to create an admin account.

3. You can test the web application locally by setting DEBUG = True in settings.py and running the following:

   python manage.py runserver

   Then visit http://127.0.0.1:8000/layerindex/ with your browser. As with all Django applications there is an admin interface available at http://127.0.0.1:8000/admin/ also. The initial login and password will be those you entered in the step above when creating an admin account.

   NOTE: This local server should only be used for testing - for production you need to use a proper web server and have DEBUG set to False.

4. You'll need to add at least the openembedded-core layer to the database, or some equivalent that contains conf/bitbake.conf for the base system configuration. To add this, follow these steps:

   4.1. With the server running, go to the main page (see above) and click on the "Log in" button on the top right. Use the login/password you added in step 2 above.

   4.2. Click on the "Submit Layer" button in the top right and enter the details for the core layer. To use the real openembedded-core layer, use these values:

    Layer name:               openembedded-core
    Layer type:               Base
    Summary:                  Core metadata
    Description:              Core metadata
    Repository URL:           git://git.openembedded.org/openembedded-core
    Repository subdirectory:  meta
   
    Once you have filled in the required values, click on the
    "Submit Layer" button.
   
    NOTE: The name of the layer must be "openembedded-core",
    unless you change CORE_LAYER_NAME in settings.py to match
    whatever alternative name you use here.
   

   4.3. The layer has been added but is not yet published. (For the public index this provides some protection against spam and malformed entries.) To publish it, click on the orange number next to your login name at the top right, click on the newly added layer entry, and then click on "Publish Layer".

5. Set the site name (as displayed in the top bar and page titles) by going into the admin interface (http://127.0.0.1:8000/admin/), clicking on "Sites" at the bottom, and editing the first entry, setting "Display name" to the desired name.

6. You may wish to customise some of the page templates to suit your installation, in particular:

   • templates/base.html
   • templates/layerindex/about.html

Usage

On a regular basis you need to run the update script:

path/to/layerindex/update.py

This will fetch all of the layer repositories, analyse their contents and update the database with the results. Note that if you set up more than just the master branch in the database, you will need to run the script once for each branch using -b (or --branch) to specify the branch name. Run the script with --help for further information on available options.
