A Rails 3.2.x application that demonstrates how to use Cancannible gem for role-based access permissions.

This can be used interactively at cancannibledemo.evendis.com.

See cancannibledemo4.evendis.com for the Rails 4.x version of the demo, with source also on GitHub.

# clone the app and bundle (NB: assumes you have a working ruby 1.9.3 environment)
git clone https://github.com/evendis/cancannible_demo.git
cd cancannible_demo
bundle install

# create and verify a db user (the app uses PostgreSQL by defualt)
psql postgres -c "create role cancannible_demo with login superuser"
psql postgres -U cancannible_demo -c "\c"

# setup the database
rake db:setup

# now you are ready to go..
rails s
open http://localhost:3000

Tests are written with RSpec and are found in the ./spec folder.

Only tests that specifically demonstrate cancannible-related behaviour are included, to avoid confusing the issue.

Guard is also included in the development bundle, so if you wish you can fire it up to run tests as you change files:

bundle exec guard

The application uses haml for convenience and clarity. There's no dependency however; all this works fine with ERB or other view styles.

I'm also using inherited_resources for automatic RESTful bahaviour. Yes, it is officially deprecated, but I've yet to find anything that is better than "zero code"!

However, you may not agree (and maybe I'll change my mind one day), so the customers_controller.rb provides an example of how this all works with plain old controllers and standard ERB.
