======================================
Setting up the development environment
======================================

Fork the repo and run::

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

Playing in the sandbox
======================

Oscar ships with a 'sandbox' site which can be run locally to play around with
Oscar using a browser. Set it up by::

   make sandbox 
   cd sites/sandbox 
   ./manage.py runserver

This will create the database and load some fixtures for categories and shipping
countries.

Note that Oscar uses PIL_ and Sorl_ for thumbnailing, and so you will need
``libjpeg-dev`` installed in your OS so that your PIL installation supports
JPEGS.

.. _Sorl: http://sorl-thumbnail.readthedocs.org/en/latest/

Writing LESS/CSS
================

The sandbox Oscar site defaults to serving the CSS files directly, bypassing
LESS compilation.  If you want to develop the LESS files, set::

    USE_LESS = True
    COMPRESS_ENABLED = False

in ``sites/sandbox/settings_local.py``.  You will also need to ensure that
``lessc`` is installed.  This can be acheived by running::

    pip install -r requirements_less.txt

which will install the `virtual-node`_ and `virtual-less`_ packages, which will
install node.js and LESS in your virtualenv.

Vagrant
=======

Oscar ships with a Vagrant_ virtual machine that can be used to test integration
with various services in a controlled environment.  For instance, it is used to
test that the migrations run correctly in both MySQL and Postgres.

.. _Vagrant: http://vagrantup.com/

Building the Vagrant machine
----------------------------

To create the machine, first ensure that Vagrant and puppet_ are installed.  You will require a
puppet version that supports ``puppet module install``, that is > 2.7.14.  Now
run::

    make puppet

.. _puppet: http://docs.puppetlabs.com/guides/installation.html

to fetch the required puppet modules for provisioning.  Finally, run::

    vagrant up

to create the virtual machine and provision it.

Testing migrations against MySQL and Postgres
---------------------------------------------

To test the migrations against MySQL and Postgres, do the following:

1. SSH onto the VM::

    vagrant ssh

2. Change to sandbox folder and activate virtualenv::

    cd /vagrant/sites/sandbox
    source /var/www/virtualenv/bin/activate

3. Run helper script::

    ./test_migrations.sh

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

Testing WSGI server configurations
----------------------------------

You can browse the Oscar sandbox site in two ways:

* Start Django's development server on port 8000::

    vagrant ssh
    cd /vagrant/sites/sandbox
    source /var/www/virtualenv/bin/activate
    ./manage.py runserver 0.0.0.0:8000

  The Vagrant machine forwards port 8000 to post 8080 and so the site can be
  accessed at http://localhost:8080 on your host machine.

* The Vagrant machine install Apache2 and mod_wsgi.  You can browse the site
  through Apache at http://localhost:8081 on your host machine.
