Setting up the development environment on Ubuntu

Warning: this page could be outdated. take ideas from https://github.com/p2pu/lernanta/wiki/Lernanta%27s-Setup-Install if you want to help us maintaining it

Please note that your system most be updated before following these instructions. These instructions have been adapted from the README.rst.

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
sudo apt-get install swig
sudo apt-get install python-imaging
sudo apt-get install python-m2crypto
sudo apt-get install gettext python-iso8601

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 git@github.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/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: :

./sh/rmpyc

If the mysql database doesn't exist yet, create it. To do this, run the mysql command line: :

mysql -u root -p

Create the database 'lernanta' and a user to access it (we'll use 'lernantauser', with the password 'lernantapass'): :

create database lernanta; 
grant usage on *.* to lernantauser@localhost identified by 'lernantapass';
grant all privileges on lernanta.* to lernantauser@localhost;

To run tests, you'll also need to create a test database: :

create database test_lernanta;
grant all privileges on test_lernanta.* to lernantauser@localhost;

To test that you can login with your mysql user, quit mysql and from the terminal command line run: :

mysql -u lernantauser -p lernanta

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. :

./sh/syncdb

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 tests: :

# The first time
FORCE_DB=1 python manage.py test
# After the first time
python manage.py test

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
