Specifying the correct path for Show and Edit actions for nested resources

Question

I have 2 models

father.rb:

class Father < ActiveRecord::Base has_many :sons, dependent: :destroy end 

son.rb

 class Son < ActiveRecord::Base belongs_to :father end 

routes.rb

 Family::Application.routes.draw do resources :fathers do resources :sons end end 

output of rake routes:

 father_sons GET /fathers/:father_id/sons(.:format) sons#index POST /fathers/:father_id/sons(.:format) sons#create new_father_son GET /fathers/:father_id/sons/new(.:format) sons#new edit_father_son GET /fathers/:father_id/sons/:id/edit(.:format) sons#edit father_son GET /fathers/:father_id/sons/:id(.:format) sons#show PATCH /fathers/:father_id/sons/:id(.:format) sons#update PUT /fathers/:father_id/sons/:id(.:format) sons#update DELETE /fathers/:father_id/sons/:id(.:format) sons#destroy fathers GET /fathers(.:format) fathers#index POST /fathers(.:format) fathers#create new_father GET /fathers/new(.:format) fathers#new edit_father GET /fathers/:id/edit(.:format) fathers#edit father GET /fathers/:id(.:format) fathers#show PATCH /fathers/:id(.:format) fathers#update PUT /fathers/:id(.:format) fathers#update DELETE /fathers/:id(.:format) fathers#destroy 

schema.rb

 ActiveRecord::Schema.define(version: 20130626013724) do create_table "fathers", force: true do |t| t.string "name" t.integer "age" t.datetime "created_at" t.datetime "updated_at" end create_table "sons", force: true do |t| t.string "name" t.integer "age" t.integer "father_id" t.datetime "created_at" t.datetime "updated_at" end add_index "sons", ["father_id"], name: "index_sons_on_father_id" end 

The question is, what paths and parameters should be indicated for the places marked AA, BB, CC and DD below? This is part of the app / views / sons / index.html.erb file:

  <% @sons.each do |son| %> <tr> <td><%= son.name %></td> <td><%= son.age %></td> <td><%= link_to 'Show', AA %></td> <td><%= link_to 'Edit', BB(CC) %></td> <td><%= link_to 'Destroy', DD, method: :delete, data: { confirm: 'Are you sure?' } %></td> </tr> <% end %> 

I can add resources to my son. The problem is to specify its display and editing patches.

Code is also available on github .

Answer 1

Read Nested Rsources and Create -Nested Resources

 <td><%= link_to 'Show', father_son_path(@father, son) %></td> <td><%= link_to 'Edit', edit_father_son_path(@father, son) %></td> <td><%= link_to 'Destroy', [@father, son], confirm: 'Are you sure?', method: :delete %></td> 

Answer 2

for editing edit_father_son(son.father, son) for the show father_son(son.father, son) I say from memory, maybe it is (son, son. Father), but you should have an idea.
