Cream Rails 3 demo app – Active Record

This is app serves to demonstrate how to configure a Rails 3 app for use with Cream and Active Record

Create Rails 3 app without Active Record

  $ rails new cream_app —skip-activerecord  

  $ cd cream_app

Install Cream

Insert in Gemfile

  gem 'cream'

Install using bundler

$ bundle install

A set of gems related to Cream are installed…

  Using cancan (1.4.1)

  Using cancan-permits (0.3.6)

  Using cancan-rest-links (0.2.0)

  Using devise (1.1.5) 

  Using devise-links (0.2.1)

  Using cream (0.7.8)  

  $ rails g

Now we have a lot of interesting generators at our disposal related to Cream

  Cancan:

    cancan:config

    cancan:license

    cancan:licenses

    cancan:permit

    cancan:permits

    cancan:restlinks

Cream:
cream:app
cream:full_config
Devise:
devise
devise:config
devise:install
devise:links
devise:users
devise:views

Permits:
permits:config
Roles:
roles:config

Check the run options for the main generator

Check out the options available when running the cream:full_config generator

  $ rails generate cream:full_config -h

The —orm and —strategy options are essential.

Do a Full Cream configuration of the app

The following will set up the app using:

• a simple role_string role strategy (role attribute of type String on the User model)
• mongoid as the ORM
• create a devise Admin user that inherits from User

  $ rails g cream:full_config --orm active_record --strategy role_string --admin-user

Note: You can leave out the orm option as Active Record is the default orm.

Run migrations

  $ rake db:migrate

Note you can also supply the -m option to the ‘cream:full_config’ generator in order to autorun migrations as the final step ;)

Start the server

Ready to rock!

  $ rails server

From here on, read the README of the individual subproject that Cream consists of, such as devise, cancan, cancan-permits and so on to enhance this application.

Note: Currently there is even no devise routes in this app!
