Adding a New Page to a Rails 4 Application

Question

I have a new Rails project, in the project I have a controller, view and model with a name Customer. Now I need to, in addition to the actions, CRUDI need to add two new pages, for example:

1. http://0.0.0.0:3000/Customer/sale

2. http://0.0.0.0:3000/Customer/lease

And I want to paste the code into these files. How can I achieve this, I mean creating new links saleand lease?

Answer 1

In your file routes.rbyou can add these two routes:

  resources :customers do
    collection do
      get 'create_sale' => 'customers#create_sale', as: :create_sale
      get 'create_lease' => 'customers#create_lease', as: :create_lease
    end
  end

Then you can add two new methods (actions) to your file customers_controller.rb:

  def create_sale
    # your logic goes here
  end

  def create_lease
    # your logic goes here
  end

app/views/customers/ create_sale.html.erb create_lease.html.erb, , .

Answer 2

#config/routes.rb
resources :customers do
   %w(sale lease).each do |route|
      get route.to_sym, action: route.to_sym, as: route.to_sym
   end
end

:

#app/controllers/customers_controller.rb
class CustomersController < ApplicationController
    def sale
    end

    def lease
    end
end
