Question

I am playing with custom view and routes. I think that I have everything right but obviously not. Essentially I tried to copy the show method and show.html.erb but for some reason it will not work.

My controller

    class fatherController < ApplicationController
      def show
        @father = Father.find(params[:id])

        respond_to do |format|
         format.html # show.html.erb
         format.xml  { render :xml => @father }
        end
      end

      def ofmine
        @father = Father.find(params[:id])

        respond_to do |format|
          format.html # show.html.erb
          format.xml  { render :xml => @father }
        end
      end
   end

My routes.rb

Parent::Application.routes.draw do
  resources :fathers do
     resources :kids
  end 

  match 'hospitals/:id/ofmine' => 'father#show2'
end

when I go to

127.0.0.1:/father/1

it works fine but when I try to go to

127.0.0.1:/father/1/ofmine

it gives the following error. It doesn’t matter what the variable/method that is called; it occurs at the first one to be displayed. Both show.html.erb and show2.html.erb are the exact same files

My Error from webserver commandline

Error as displayed on actual page

NoMethodError in Fathers#show2

Showing
/var/ruby/chs/app/views/fathers/show2.html.erb
where line #7 raised:

undefined method `name’ for
nil:NilClass

Extracted source (around line #7):

@father.name %> 8:

If anyone could tell me what in the world I am doing wrong I would appreciate it greatly.

Here is a copy of my rake routes

     father_ofmine      /fathers/:father_id/ofmine(.:format)               {:action=>"show2", :controller=>"fathers"}

Answer 1

Routes are taken into account according to their order of appearance in your routes file.

I guess 127.0.0.1:/father/1/ofmine is interpreted as part of resources :fathers

Put match 'hospitals/:id/ofmine' => 'father#show2' at the top of your routes.rb to try

EDIT 1:

I guess, you made a mistake:

# instead of match 'hospitals/:id/ofmine' => 'father#show2' 
match 'father/:id/ofmine' => 'father#show2'

And to have a cleaner file, I’d do:

Parent::Application.routes.draw do
  resources :fathers do
    match '/ofmine' => 'father#show2'
    resources :kids
  end 
end

EDIT 2:

Do you have a show2 method in your controller which gets the variable?

I’m thinking, you’re assuming the current ofmine method handles the situation which is wrong
