Setting up the development environment

Fork the repo and run:

$ git clone git@github.com:<username>/django-oscar.git
$ cd django-oscar
$ mkvirtualenv oscar  # needs virtualenvwrapper
$ make install

If using Ubuntu, the python-dev package is required for some packages to compile.

The sandbox site can be used to examine changes locally. It is easily created by running:

$ make sandbox

JPEG Support

On Ubuntu, you need to install a few libraries to get JPEG support with Pillow:

$ sudo apt-get install python-dev libjpeg-dev libfreetype6-dev zlib1g-dev

If you already installed PIL (you did if you ran make install previously), reinstall it:

$ pip uninstall Pillow
$ pip install Pillow

Creating migrations

As the sandbox is a vanilla Oscar site, it is what we use to build migrations against:

$ make sandbox
$ sites/sandbox/manage.py schemamigration $YOURAPP --auto

Writing LESS/CSS

Oscar’s CSS files are built using LESS. However, the sandbox defaults to serving CSS files directly, bypassing LESS compilation.

If you want to develop the LESS files, set:

USE_LESS = True

in sites/sandbox/settings_local.py. This will include the on-the-fly less pre-processor. That will allow you to see changes to the LESS files after a page reload.

You can manually compile the CSS files by running:

make css

For this to work, you will need to ensure that the pre-processor binary lessc is installed. Using npm, install LESS using:

npm install less

Warning

If you do submit a pull request that changes the LESS files. Please also recompile the CSS files and include them in your pull request.

Testing migrations against MySQL and Postgres

To test the migrations against MySQL and Postgres you will need to set up an environment with both installed and do the following:

1. Change to sandbox folder and activate your virtualenv

2. Run helper script:

   ./test_migrations.sh
   
   This will recreate the Oscar database in both MySQL and Postgres and rebuild
   it using ``migrate``.
