How to Create Basket of Shop site model in rails 4?

My project is about an online shopping site, using Ruby on Rails to buy phones. My Database is User, Product, Phone. I'm trying to create Basket model.

My route:

resources :products do
    resources :phone do
      resources :baskets
    end
end

And my Code is:

class User < ActiveRecord::Base
    has_many :baskets
end

class Phone < ActiveRecord::Base
   belongs_to :product
   has_many :baskets
end

class Basket < ActiveRecord::Base
   belongs_to :user
   belongs_to :phone
end

When i in the Show action of Product,it Show name of Product and index Phones in this Product,i want to add 1 Phone to Basket,the error is :

No route matches {:action=>"new", :controller=>"baskets", :id=>"38", :product_id=>"30"} missing required keys: [:phone_id]

I think the problem is :

http://localhost:3000/products/30/phone/38

It's Product_id = 30,but not Phone_id = 30,in here just is Id = 30. Someone could help me fix it !

Regardless of whether you got it working (I upvoted @Andrey's answer), you'll want to consult your routing structure.

Resources should never be nested more than 1 level deep. docs

In your case, I am curious as to why you have phones nested inside products. Surely a phone is a product?

Further, why are you including resources :baskets? Surely the basket functionality has nothing to do with whether you're adding a product, phone, or anything else?

I would personally do the following:

resources :products, only: [:index, :show] do
   resources :basket, path:"", module: :products, only: [:create, :destroy] #-> url.com/products/:product_id/
end

#app/controllers/products/basket_controller.rb
class Products::BasketController < ApplicationController
   before_action :set_product

   def create
      # add to cart
   end

   def destroy
      # remove from cart
   end

   private

   def set_product
      @product = Product.find params[:product_id]
   end
end

I've implemented a cart (based on sessions) before (here).

I can give you the code if you want; I won't put it here unless you want it. It's based on this Railscast.

resources :products do
  resources :phone do
    resources :baskets
  end
end

means you have to have route like this:

/products/:product_id/phones/:phone_id/baskets/:basket_id(.:format)

Which means, that in link_to you should pass the phone_id as well:

link_to 'show basket' product_phone_basket_path(product_id: @product.id, phone_id: @phone.id, basket_id: @basket.id)
link_to 'New basket' new_product_phone_basket_path(product_id: @product.id, phone_id: @phone.id)
