Ruby on rails FriendlyId改为重定向到篮子或更正链接

我刚刚安装了FriendlyID来更改我网站的URL。 我已经为类别设置了此选项，尽管链接会发生变化，当我单击它们时，url会变为

basket/（正确的产品）

这真的是一个bug，我已经阅读了下面的代码，删除了所有的篮子引用，但它仍然存在。 有人能给我指出正确的方向吗

Category.rb

class Category < ActiveRecord::Base
  extend FriendlyId
  friendly_id :title, use: [:slugged, :history]
  has_many :products
end

My categories\u controller.rb

class CategoriesController < ApplicationController
  before_action :set_category, only: [:show, :edit, :update, :destroy]
   before_action :set_basket, only: [:show, :destroy]
  rescue_from ActiveRecord::RecordNotFound, with: :invalid_basket

  # GET /categories
  # GET /categories.json
  def index
    @categories = Category.all
    @top_ups = @categories [8]
    @log_stores = @categories [6]
    @smokeless_coal = @categories [5]
    @log_packages = @categories [4]
    @seasoned_logs = @categories [3]
    @kiln_dried_hardwood_logs = @categories [1]
    @logs_for_pizza_ovens = @categories [2]
    @logs_for_firepits = @categories [9]
  end

  # GET /categories/1
  # GET /categories/1.json
  def show
    @products = Product.where(category_id: params[:id])
    if request.path != category_path(@category)
      redirect_to @category, status: :moved_permanently
    end
  end

  # GET /categories/new

您需要在控制器中使用友好的find方法。例如，代替

def set_category
  @category = Category.find(params[:id])
end

你应使用：

def set_category
  @category = Category.friendly.find(params[:id])
end

此外，还要注意执行两次

find

操作的情况。例如，在您的

baskets控制器#show

操作中，您正在调用

set\u basket

（当前调用

basket.find（params[:id]）

，您应该更改它以执行

basket.friendly.find（params[:id]）

在_action之前通过，但随后在#show操作的主体中再次设置相同的实例变量。您的BasketsController#show操作应为：

def show
end

感谢您的帮助。感谢您的帮助。我现在遇到了产品未显示到类别的问题。参数[：id]现在不再匹配，因为它等于新的url路径。很抱歉，如果这是基本的，我是ruby新手。我不确定您所说的“参数[：id]现在不再匹配”是什么意思您遇到的错误是什么？我正在尝试显示每个类别中的产品。我通过以下操作完成了此操作，但是，现在产品将不会显示。

def show@products=Product.where（category\u id:params[：id]）if request.path！=category\u path（@category\u id）重定向到@category，status:：moved\u permanually end

在执行操作之前，您已经在

中设置了
@category
，所以只需执行
@products=Product。其中（category:@category）
。一般来说，在已经有对象的地方，最好传递该对象并让Rails插值，而不是传递id或slug。
def set_category
  @category = Category.find(params[:id])
end

def set_category
  @category = Category.friendly.find(params[:id])
end

def show
end
