Lernanta is the new platform for P2PU. We are building on the codebase from Batucada, a rewrite of drumbeat.org by Mozilla.

Setting up a local development environment in Ubuntu (Please note that your system most be updated before following these instructions.)
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-core sudo apt-get install libxml2-dev sudo apt-get install libxslt-dev sudo apt-get install mysql-client sudo apt-get install mysql-server sudo apt-get install libmysqlclient-dev sudo apt-get install python-dev sudo apt-get install python-setuptools
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 email@example.com:<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 sudo 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 need to create the user you'll use. 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 not installed a local version of mysql, you will need to do so now.
Next, sync the database and run migrations.
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
