Intercession¶ ↑

• github.com/jbarnette/intercession

Treat your sessions like models, not hashes. Intercession mixes a module into the session on each request, allowing you to nicely encapsulate (and test!) lots of user and session-specific behavior.

Check out this gist: gist.github.com/44506

Unit tests for your session model! Mix it in to a Hash and go to town:

def setup
  @session = Hash.new
  @session.extend Transient::Session
end

def test_session_user_lazily_loads_from_user_id
  assert_nil @session.user
  @session[:user_id] = users(:default).id
  assert_equal users(:default), @session.user
end

I’ve used Intercession 2.x with Rails v2.2.2 and v2.3.4. People apparently use Intercession 3.x with Rails 3.x. Anything else might give you hives.

Intercession works as a plugin or a gem. If you install it as a plugin, it’ll create you a stub session module in app/models/transient/session.rb. If you’re using it as a gem, do it yourself. :)

As a plugin:

$ script/plugin install git://github.com/jbarnette/intercession.git

As a gem (preferred):

$ gem install intercession

If you’re using Intercession as a gem, add it to your app’s gem dependency mechanism.

After installation, add include Intercession to your ApplicationController. To enable Intercession in your tests, call Intercession.test! in your test_helper.rb.
