Ruby on rails ActiveRecord:：RecordNotFound:无法'；找不到id为的债务人=

我最近将一个项目从MongoDB/mongoid转换为PostgreSQL。在转换之后，我所有的模型规格都通过了，我的大多数控制器规格都通过了。不过，我的三个控制器没有通过测试

根据以下模型定义，警报、订单和用户模型取决于客户和债务人模型：

class Client < ActiveRecord::Base
  has_many :users, autosave: true, dependent: :destroy
  has_many :alerts, autosave: true, dependent: :destroy
  has_many :orders, autosave: true, dependent: :destroy

  ...
end

class Debtor < ActiveRecord::Base
  has_many :orders, autosave: true
  has_many :alerts, autosave: true

  ...
end

class Alert < ActiveRecord::Base
  belongs_to :client
  belongs_to :debtor

  ...
end

class Order < ActiveRecord::Base
  belongs_to :client
  belongs_to :user
  belongs_to :debtor

  ...
end

class User < ActiveRecord::Base
  rolify

  devise :database_authenticatable, 
     :recoverable, :rememberable, :trackable, :validatable

  has_and_belongs_to_many :roles, :join_table => :users_roles
  belongs_to :client
  has_many :orders
end

相关控制器操作：

class OrdersController < ApplicationController
  before_filter :authenticate_user!
  before_filter :load_client
  before_filter :has_enough_units, :only => [:create]
  respond_to :html
  load_and_authorize_resource :debtor
  load_and_authorize_resource :order, :through => :client, :shallow => true

  def index
    if @client == nil
      @orders = Order.all
    else
      @orders = @client.orders.all
    end
    respond_with(@orders)
  end

  def show
    if @client == nil
      @order = Order.find(params[:id])
    else
      @order = @client.orders.find(params[:id])
    end
  end

  def new
    if current_user.has_role? :admin
      @order = Order.new
    else
      @order = @client.orders.build
    end
    @order.build_debtor
    @clients = Client.all.to_a
  end

  ...
end

class OrdersController[：create]
回复：html
加载和授权资源：债务人
加载和授权资源：顺序，：通过=>:client，：shall=>true
def索引
如果@client==nil
@订单=Order.all
其他的
@订单=@client.orders.all
结束
用（@orders）响应_
结束
def秀
如果@client==nil
@order=order.find（参数[：id]）
其他的
@order=@client.orders.find（参数[：id]）
结束
结束
def新
如果当前用户具有角色？：管理
@order=order.new
其他的
@订单=@client.orders.build
结束
@订单.构建\债务人
@clients=Client.all.to_a
结束
...
结束

希望这是足够的信息…

您还应该显示规格和控制器中发生的情况。这就是错误发生的地方。我添加了部分规范和控制器。我没有做任何事情只是为了减少代码量，但如果需要，我可以发布更多。

require 'spec_helper'

describe OrdersController do
  before (:each) do
    @user, @user2, @user3, @admin = FactoryGirl.create(:user), FactoryGirl.create(:user), FactoryGirl.create(:user), FactoryGirl.create(:user)
