acts_as_inviteable

A simple to use plugin for creating an invite system for an app.

Generator

Use the generator to get started:

script/generate invitations_for User

This will add 2 routes to your routes file (config/routes.rb) you may wish to edit these:

map.resource :invitation, :only => [:new, :create]
map.signup   '/signup/:invite_code', :controller => 'users', :action => 'new'

It will also add acts_as_inviteable to your User model.

After running the generator you need to run rake db:migrate to add the invitations table and invitation_limit column.

Options

By default users are allowed to invite 5 others. You can customize this by providing an option to acts_as_inviteable.
Change how you call acts_as_inviteable in your users model by adding the default_invitation_limit option:

acts_as_inviteable :default_invitation_limit => 20
