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  .
You will need to configure git and upload your SSH keys to github
You need a few libraries and can grab them with this command:
sudo apt-get install git libxml2-dev libxslt-dev mysql-client mysql-server libmysqlclient-dev python-dev
To obtain the lernanta's source code that you will be modifying, first fork the repository on the github website and then clone it by running:
git clone firstname.lastname@example.org:<your github username>/lernanta.git
Next, you'll need to install virtualenv and 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 libxml2-dev and 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 .pyc files:
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>
Create a 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
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
