Ruby on rails 3 link_to controller and action

Question

I know this is probably a pretty simple concept. I am trying to create a link to a controller and action. For example I have a link in my layout file to update a record when a link is clicked, so I need to be able to link to the controller and action. How would I accomplish this?

You use link_to to link to an action on a controller. You need to provide more information to get the full answer. Could you provide the name of your controller and the action you require? – Crenelation

Answer 1

link_to "Label", :controller => :my_controller, :action => :index

See url_for.

also often it is not bad idea to set :method if it is different from :get – Sheatfish

Also with CSS:

<%= link_to "Purchase", { :controller => :transactions, :action => :purchase }, { class: "btn btn-primary btn-lg", style: "width: 100%;" } %>

If you want to pass params too then do

<%= link_to student.name,  controller: "users", action: "show", id: student.id, partial: "profile"  %>

For Rails 6:

 <%= button_to "SIGN IN", { controller: 'o_auth', action: :login }, { class: "btn btn-primary btn-lg", style: "width: 100%;", method: :get} %>
