[Rails] Question about link_to

2011-08-06 Thread Pepe Sanchez 
Hi all

I am working on the first  application from the book Head First Rails
called tickets. What I do not understand is where the variable
new_ticket_path gets populated in the view index.html.erb


%= link_to 'New Ticket', new_ticket_path %

Please advise

This path is made up by the rails router. If you have  
'resources :tickets' in your routes file, then this path is generated  
automatically for you. Type rake routes in your Terminal to see the  
whole lot of them.


There's an excellent Rails Guide about this, called Routing from the  
Outside In.
