Lernanta is the new platform for P2PU. We are building on the codebase from Batucada, a rewrite of drumbeat.org by Mozilla.
Interested in getting involved in Lernanta code development? Check out the development wiki  for more info! For a broader view on the development and tech team at P2PU, check out the P2PU Development and Tech team  page on the P2PU wiki  .
Setting up a local development environment in Ubuntu
You will need to set up git and your SSH keys
You need a few libraries and can grab them with this command:
sudo apt-get install virtualenvwrapper libxml2-dev libxslt-dev mysql-client mysql-server libmysqlclient-dev python-dev
To install Lernanta, you must clone the repository:
git clone git://github.com/p2pu/lernanta.git
If you're planning on contributing back to the project, fork the repository instead in the usual GitHub fashion.
Next, you'll need to install
pip if you don't already have them. Using virtualenvwrapper is also recommended.
sudo easy_install virtualenv sudo easy_install pip pip install virtualenvwrapper
Be sure to configure your shell so that pip knows where to find your virtual environments:
# in .bashrc or .bash_profile export WORKON_HOME=$HOME/.virtualenvs export PIP_VIRTUALENV_BASE=$WORKON_HOME export PIP_RESPECT_VIRTUALENV=true source /usr/local/bin/virtualenvwrapper.sh
Once installed, create your virtual environment for
lernanta and install the dependencies. There's a chance that packages listed in
requirements/compiled.txt won't install cleanly if your system is missing some key development libraries. For example, lxml requires
libxslt-dev. These should be available from your system's package manager.
cd lernanta mkvirtualenv --no-site-packages lernanta workon lernanta pip install -r requirements/compiled.txt pip install -r requirements/prod.txt pip install -r requirements/dev.txt
To be extra sure you're working from a clean slate, you might find it helps to delete
If the mysql database doesn't exist yet, create it. You will use the database name, user, and password in the next file (settings_local.py)
mysqladmin -u <user> -p create <database name>
settings_local.py based on the template provided in the checkout. Edit the database parameters as needed
cp settings_local.dist.py settings_local.py
If you have yet to get a local version of mysql running you will want to do so now.
Next, sync the database and run migrations.
python manage.py syncdb --noinput --migrate
Finally, start the development server to take it for a spin. You can register a new account and look in the terminal window where the server is running to find the activation link (If you get 404 error for that url, remove the "=": http://www.flickr.com/photos/digifoo/5593967846/).
python manage.py runserver
To run the test framework.
python manage.py test
To recreate the test database before running the tests.
FORCE_DB=True python manage.py test
After updating a database model you will have to make a migration for the change. See the documentation for more information: https://github.com/p2pu/lernanta/blob/master/docs/migrations.txt
Once you have your development environment running, you can make changes or get the latest from github. See the wiki for more information: https://github.com/p2pu/lernanta/wiki
