The software is a standard DJango application for installation and deployment consult the documentation at the DJango website.
The application itself consists of 2 parts. A simple Content model that manages authored pages, and a metadata model for providing views onto the metadata associated with the manuscripts. The application allows view, creation, editing and deletion of the content model. The application only allows view of the metadata model, with data being ingested into the application via an administrator managed load process.
The application requires python image utilities, which can be installed with $ easy_install pil
Data loading is a 2 step process. There is a script, Migrate.py that creates json files, one per record from the existing meta data database (currently a MySQL instance). This is run on the commandline and requires access to that database. The json files are loaded via a administrative web UI into the Django model which is stored in whichever RDBMS backend the Django instance is configured to use.
The content model is populated by loading JSON files from disk using the same web UI. Once loaded the content pages can be edited by a suitably authenticated user in the web UI.
Please note all commands are run in src/ShahnamaDJ/ where manage.py is located.
First edit settings.py. You will need to adjust any absolute paths in there, and may wany to select a different database type than sqllite if you are running in production. Note that SOURCE_DATA is relevent to the migration process and contains example editorial content.
Data is migrated using the Migrate.py script. That script contains a MySQL connection which will need to be edited to point to the existing shahnama database. Running this script will extract all the data and create thousands of files under the location specified by SOURCE_DATA in settings.py
If you are not using sqllite, you will have to create a user in the database as per your settings.py, and allow that user to create tables, indexes etc. Django recommends PostgreSQL.
Once you have done that, run python manage.py syncdb to create the database. You will be asked for an admin user, please make certain that you use a secure password if you are going to make the /admin URL visible to the world.
Start the development server, so that you can load the data. Please DO NOT use the development server to run in production, go and read the Django documentation (and use mod_python as recommended)/.
Run python manage.py runserver
Login as the admin user (created in Step 3) and go to http://localhost:8080/admin/loadDb. At this page, read the instructions and load the database with the Shahnama data you migrated in step 2. Remember to tick the checkbox so that it loads the data. If you don't the loadDB action will only check and resolver internal references.
You can also load editorial content from SOURCE_DATA/content on http://localhost:8080/admin/loadDb. Once you have loaded this content (there are example files in the source repository), you can edit them online. Any user in the DJango database with content.pageedit, content.createpage, content.pageview, content.imageupload can perform those actions on editorial content. Consult the Django documentation on how to give users permissions. content.pageview allows users to see a list of all content pages.
Any standard deployment method for Django can be used. If deploying for production you may want to use an alternative authentication framework (eg SSO), and you should look at configuring caching. The responses at each URL are cacheable and vary by URL. Doing this will eliminate all database load from the system.
You should consult the Django documentation for information on deployment and configuration with SSO systems.
The code base uses DJango unit tests. Some of the test use fixtures. The following fixtures are used during testing. src/ShahnamaDJ/contenttest.json and src/ShahnamaDJ/recordstest.json. Thes can be created by dumping your working DJango database python manage.py dumpdata. If you choose to run Django unit tests ie python manage.py test with a complete database in recordstest.json (ie abotu 44MB of json) the test suite will load and validate all 30K+ pages which will take about 1H. (Unit tests are single threadded)
