Question

I have a strange problem with my Rails routing .
I have a controllers called Page and a method called Page#dashboard

When I try to access /dashboard/1 the dashboard method of Page Controller never gets executed.
But surprisingly the /pages/dashboard.html.erb is rendered fine .

Can someone explain me why ?

Code details as below . Thanks

Trying to access – /dashboard/1

Routes.rb

match '/dashboard/:id' => 'page#dashboard'

Page_Controller.rb

class PageController < ApplicationController

  before_filter :init

  private

  def init

    puts "init getting executed !!!!!!!!!"  #this gets printed on console

  end

  def dashboard

     puts "dashboard getting executed !!!!!!!!!" #this doesnt get printed on console


  end

end

viewPage – Pages/dashboard.html.erb

The logs are shown as below –

init getting executed !!!!!!!!!

First off, you don’t have to define an action method. If all you want to do is render a template then as long as the template foo exists, rails will happily allow you to route to SomeController#foo.

Secondly, for a method to be an action is has to be public. Your dashboard method is private so it doesn’t count as an action and doesn’t get executed. Since you have a dashboard.html.erb template, rails does however render that.
