one more time with RoR

Today I'm interesting again for testing some of the RoR gems that I was reading and researching a long time ago, but combined all together.

• rails_admin
• devise
• cancan
• papertrail

Just to become a nice and easy start up app within a few seconds.

First I added the necessary gems to the Gemfile:

As I was using openshift, I had to get rid of the pg (not used, I'm using mysql || sqlite3).

Then:

rails g rails_admin:install

(mounting admin as /admin, the default option)
Then for devise:

rails generate devise:install
rails g devise:views
rails g devise User

For CanCan:

rails g cancan:ability

And for PaperTrail:

rails generate paper_trail:install --with-changes --with-associations

After that, only last to add the ":username" to the User model

rails g migration AddUsernameToUser username:string

Then the usual

bundle exec rake db:migrate

And for the groups, if needed:

rails g model Role name:string
rails g migration addRoleIdToUser role:references
rake db:migrate

And the base is quite OK
