Updating dev environment setup
* Script now installs RVM in conventional location (~/.rvm) by default, though it allows for the override if desired. This will enable folks to install edX alongside other Ruby projects also using RVM. * Script now uses virtualenvwrapper to ease the process of enabling the edX virtualenv and to allow for easy switching back and forth between virtualenv projects. It now also installs the "mitx" virtualenv in the conventional location of ~/.virtualenv. * Adding a .rvmrc file so that the Ruby environment will be automatically activated (via `rvm use`) whenever the user hits the `mitx/` directory.

Success!!
|

|

To start using Django you will need to activate the local Python
|
||||
and Ruby environment (at this time rvm only supports bash) :
|
||||
and Ruby environments. Ensure the following lines are added to your
|
||||
login script, and source your login script if needed:
|
||||
|
||||
$ source $RUBY_DIR/scripts/rvm
|
||||
$ source $PYTHON_DIR/bin/activate
|
||||
source `which virtualenvwrapper.sh`
|
||||
source $RUBY_DIR/scripts/rvm
|
||||
|
||||
Then, every time you're ready to work on the project, just run
|
||||
|
||||
$ workon mitx
|
||||
|
||||
To initialize Django
|
||||
|
||||
$ cd $BASE/mitx
|
||||
$ rake django-admin[syncdb]
|

$ rake django-admin[migrate]
