It adds support to devise for send invitations by email (it requires to be authenticated) and accept the invitation setting the password.
All gems are on gemcutter, so you need to add gemcutter to your sources if you haven’t yet:
sudo gem sources -a http://gemcutter.org/
Install devise_invitable gem, it should install dependencies (such as devise and warden):
sudo gem install devise_invitable
Configure devise_invitable inside your app (and warden and devise if you weren't using them):
config.gem 'warden' config.gem 'devise' config.gem 'devise_invitable'
Follow the walkthrough for devise with the following modifications.
Add t.invitable to the migration:
create_table :users do ... t.invitable ... end add_index :users, :invitation_token # for invitable
Add :invitable to the devise line in your model:
class User < ActiveRecord::Base devise ..., :invitable end
If you are using devise :all, you can add :invitable to config.all in devise initializer:
Devise.setup do |config| ... config.all = [..., :invitable] ... end
DeviseInvitable adds a new configuration option, :invite_for. It's the time a invitation is valid for. Default value is nil, which means invitation doesn't expire.
It adds authenticate_resource! filter to restrict who can send invitations. You can override this method in your ApplicationController. Default behavior is require authentication of the same resource_name, so if you only have a model with devise it will allow to all authenticated users to send invitations.
You have to configure mailer as it's required for confirmable and recoverable.
It uses two flash messages, :send_invitation and :updated, which are translated as other flash messages from devise.
Adding Invitable to a running application
Define a migration to add invitable to your model:
change_table :your_table do |t| t.string :invitation_token, :limit => 20 t.datetime :invitation_sent_at t.index :invitation_token end
Add :invitable to the devise line of your model, or to config.all in devise initializer if your model uses devise :all.
Override authenticate_resource! filter if you need to customize who can send invitations.
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
