Welcome for Family Budget

This is the code for a website, which will help you manage your finances.

Info

Currently the alfa version (FBA) is deployed to the RedShift server of QMUL.
Here is the URL of the website: http://fba-dev.apps.devcloud.eecs.qmul.ac.uk
This website is also used as a course project for the Cloud Computing module at Queen Mary University of London.
It demonstrates how a PaaS like RedShift can be easily used as a platform for the creation of websites with various functionalities.

Repo layout

wsgi/ - Externally exposed wsgi code goes wsgi/static/ - Public static content gets served here libs/ - Additional libraries data/ - For not-externally exposed wsgi code setup.py - Standard setup.py, specify deps here ../data - For persistent data (also env var: OPENSHIFT_DATA_DIR) .openshift/action_hooks/pre_build - Script that gets run every git push before the build .openshift/action_hooks/build - Script that gets run every git push as part of the build process (on the CI system if available) .openshift/action_hooks/deploy - Script that gets run every git push after build but before the app is restarted .openshift/action_hooks/post_deploy - Script that gets run every git push after the app is restarted

Environment Variables

OpenShift provides several environment variables to reference for ease of use. The following list are some common variables but far from exhaustive:

os.environ['OPENSHIFT_APP_NAME']  - Application name
os.environ['OPENSHIFT_DATA_DIR']  - For persistent storage (between pushes)
os.environ['OPENSHIFT_TMP_DIR']   - Temp storage (unmodified files deleted after 10 days)

When embedding a database using 'rhc cartridge add', you can reference environment variables for username, host and password:

If you embed MySQL, then:

os.environ['OPENSHIFT_MYSQL_DB_HOST']      - DB host
os.environ['OPENSHIFT_MYSQL_DB_PORT']      - DB Port
os.environ['OPENSHIFT_MYSQL_DB_USERNAME']  - DB Username
os.environ['OPENSHIFT_MYSQL_DB_PASSWORD']  - DB Password

To get a full list of environment variables, simply add a line in your .openshift/action_hooks/build script that says "export" and push.

Notes about layout

Please leave wsgi, libs and data directories but feel free to create additional directories if needed.

Note: Every time you push, everything in your remote repo dir gets recreated please store long term items (like an sqlite database) in ../data which will persist between pushes of your repo.

Notes about setup.py

Adding deps to the install_requires will have the OpenShift server actually install those deps at git push time.
