为什么friendly_id在一个动作中工作而在另一个动作中失败

我的orders_controller.rb中有一些自定义操作:

class OrdersController < ApplicationController
  def process_payment
    @order = Order.friendly.find(params[:id])
    [snip]
    binding.pry_remote # drops into the terminal here for debugging
    redirect_to order_path(@order)
    [snip]
  end
end

Testivate::Application.routes.draw do
  resources :orders do
    member do
      get :pay
      post :process_payment
    end
  end
end

我可以在终端中看到,在@order#process_payment操作中,friendly_id正在运行:

[1] pry(#<OrdersController>)> @order
+----+-------+-------+------+------+------+-------+-------+-------+-------+-------+-------+-------+-------+-------+
| id | co... | url   | comp | comp | comp | us... | gu... | gu... | cr... | up... | pr... | uuid  | sp... | payed |
+----+-------+-------+------+------+------+-------+-------+-------+-------+-------+-------+-------+-------+-------+
| 1  | Th... | ht... | http | http | http | 1     |       |       | 20... | 20... | 1     | ee... | true  | false |
+----+-------+-------+------+------+------+-------+-------+-------+-------+-------+-------+-------+-------+-------+
1 row in set
[2] pry(#<OrdersController>)> @order.uuid
=> "ee1bbe01-e1ca-420c-991b-76ce90525cf8"
[3] pry(#<OrdersController>)> request.original_url
=> "http://127.0.0.1:4000/orders/ee1bbe01-e1ca-420c-991b-76ce90525cf8/process_payment"
[4] pry(#<OrdersController>)> order_path(@order)
=> "/orders/ee1bbe01-e1ca-420c-991b-76ce90525cf8"

但是当@order#process_payment尝试重定向到@order#show时,它会失败。

我收到错误:

ActiveRecord::RecordNotFound at /orders/ee1bbe01-e1ca-420c-991b-76ce90525cf8
Couldn't find Order with id=ee1bbe01-e1ca-420c-991b-76ce90525cf8

但是,奇怪的是,这个错误似乎发生在Rails尝试完成@order#show之前,因为它永远不会落入我的@order#show行动中的终端:

class OrdersController < ApplicationController
  def show
    binding.pry_remote # should drop down to terminal here for debugging, but we never get this far
    @order = Order.friendly.find(params[:id])
    respond_with @order
  end
end

为什么会这样?

其他可能相关的代码:

class Order < ActiveRecord::Base
  extend FriendlyId
  friendly_id :uuid
  after_create :generate_uuid  
  def generate_uuid
    self.update_attributes :uuid => SecureRandom.uuid
  end
end

使用Rails 4.0.2和friendly_id 5.0.3。

You'll want to look at this

friendly_id :uuid, use: [:slugged, :finders]

这基本上设置了Rails的默认find方法,以查找标准idslug。我认为这将解决您的问题
