Question

我刚刚安装了FriendlyID来更改我网站的网址。我已经为类别设置了这个，虽然链接会在我点击它们时更改为basket/(correct-product)时更改。

这真的很烦人，我已经通过下面的代码并删除了所有的篮子引用，它仍然发生。谁能指出我正确的方向？

Category.rb

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

这是在控制台中运行的代码：

Answer 1

您需要在控制器中使用友好的find方法。例如，而不是

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

您应该使用：

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

另外，请注意两次执行find操作的情况。例如，在您的BasketsController#show操作中，您正在调用set_basket（当前调用Basket.find(params[:id])，并且您应该通过{{1}更改为执行Basket.friendly.find(params[:id])然后，您在before_action操作的主体中再次设置相同的实例变量。您的#show操作应该只是：

BasketsController#show

FriendlyId重定向到篮子或更正链接
