Hello everyone, I have a MessagesController created with rails g  
scaffold and the user may create messages that get saved, in tihs  
controller I have a method called ‘tweet’ that (using the twitter  
gem / Twitter API) triggers the given message to twitter. However I  
don’t know how to put a tweet link in my /tweets/index.html.erb… you  
know this link won’t be calling an action (edit, destroy, new), this  
link will be calling a method created by myself in the controller. Can  
you help me?

P.S: I am using rails 3.

Thanks!

Rodrigo Alves V.

routes.rb

resources :messages do  
member do  
get :tweet  
end  
end

should give you a tweet\_message\_path to use in a view like

\<%= link\_to(‘Tweet This’, tweet\_message\_path(message.id)) %\>

and direct the app to your tweet method in the messages\_controller
