Ruby on Rails Custom Method/Task

Question

I'm new to Ruby on Rails. I'm building out an app that does custom operations on defined nodes (the object). Here's my table:

<% @nodes.each do |node| %>
    <tr>
      <td><%= node.name %></td>
      <td><%= link_to 'Bootstrap', node_path(node),
              method: :bootstrap %>
      </td>
    </tr>
  <% end %>

"Bootstrap" is the custom code that I want to run. I'm defined a custom method within my Controller:

class NodesController < ApplicationController
  def bootstrap
     ......
  end
  ........
end

How do I tie in my custom code to my Rails app so that when a user clicks on the link the code will be run against that object?

In config/routes.rb, you probably have:

resources :nodes

Change this to:

resources :nodes do
  get 'bootstrap', on: :member
end

Then, run rake routes to see that you now have a new route method, bootstrap_node_path(node), and will link to /nodes/:id/bootstrap.

I recommend this over the other approach as it keeps your route details together, but that's just my personal opinion. I usually resort to custom routes as a last resort.
