Question

I am new to rails and I started working with nested resources. I have been reading this http://guides.rubyonrails.org/routing.html#nested-resources so I created 2 models, a product and a senders. Product has many Senders. My Sender model is this:

class Sender < ActiveRecord::Base
  attr_accessible :product_id, :email, :name

  belongs_to :product
end

My product is this

class Product < ActiveRecord::Base
  attr_accessible :name, :price

   #Relationships !
   has_many :senders,  dependent: :destroy
end

in my routes.rb:

  resources :products do
     resources :senders
  end 

now rake routes gives me all the right routes it should, according to http://guides.rubyonrails.org/routing.html#nested-resources

So when I type in the URL

http://localhost:3000/products/1/senders/new

so I create a new sender for my product with id = 1 I get this:

 NoMethodError in Senders#new

undefined method `senders_path' for #<#<Class:0x00000003fcf9d8>:0x00000003e6f408>

Why do I get this undefined method since it should give me the new.html.erb page for the sender of that product??

Answer 1

Notice that if you did rake routes, you would not find the route you are looking for. This is because your routes for senders are nested within products.

Therefore, if you want to create a new sender, the path should be something like new_product_sender_path(product).

So, to get all the senders of a particular product, the path would be product_senders_path(product).
