Ruby on rails 使用子例程的Rails自定义路由

我有一个问题，我正在为一家比萨店建立一个网站，在这里我有两个模型ProductCategory和Product。产品属于一个ProductCategory，其中每个类别都有许多产品。我已经将to product_categories_path命名为categories，例如product_categories#index=>categories，但现在我希望在path/product_categories.name/中有指向产品索引页面的链接，但我的路径远远不正确

Routes.config

Rails.application.routes.draw do
  resources :campaign_products
  resources :opening_hours
  resources :delivery_areas
  resources :contact_infos
  resources :delivery_times
  resources :exceptional_opening_hours
  resources :news
  resources :product_extras
  resources :product_sizes
  resources :payment_options
  resources :product_categories, path: "categories" 

  resources :products do
      get "/product_category.name", to: "products#index", as: :products_path
  end

  resources :pages
  get "/menu", to: "product_categories#index", as: :menu
  root 'pages#index'

product.rb

    class Product < ActiveRecord::Base
    belongs_to :product_category

    validates :name, presence: true, length: { in: 3..30 }, uniqueness: true
    validates :description, presence: true, length: { in: 4..300 }
    validates :product_category, presence: true
    validates_numericality_of :normal_price, :greater_than_or_equal_to => 0, :less_than_or_equal_to => 999.99
    validates_numericality_of :lunch_price, allow_nil: true, :greater_than => 0, :less_than_or_equal_to => 999.99
    validates_numericality_of :plus_size_price, allow_nil: true, :greater_than => 0, :less_than_or_equal_to => 999.99
end

class ProductCategory < ActiveRecord::Base
has_many :products

validates :name, presence: true, length: {in: 3..30}, uniqueness: { case_sensitive: false }
end

谢谢你的帮助

我会对主列表执行

category/:name

，对单个产品执行

category/{name}/:product\u id

。您可以在模型中将

重写为_param

，以便URL帮助程序使用名称而不是id。我将对主列表执行

def index
  @products = Product.all.where(:product_category_id == 1)
end
