Question

我在Ruby on Rails控制器上运行RSPEC测试，这是我正在测试的控制器操作：

控制器代码：

class Customers::AccountsController < ApplicationController
  before_action :set_customer

  def index
    @accounts = @customer.accounts
    respond_to do |format|
      format.html
      format.json
    end
  end

  def set_customer
    @customer = current_member.company.customers.find(params[:customer_id])
  end
end

以下是我的RSPEC测试代码：

before do
  @member   = FactoryGirl.create(:member)
  @company  = FactoryGirl.create(:company, owner_id: @member.id) 
  @customer = FactoryGirl.create(:customer_john_human,company_id:@company.id)
end

describe "GET INDEX" do 
  it "gets the index html page" do 
    get :index, {:customer_id=>@customer.id, :format=>:json}
  end
end

错误：

ActiveRecord::RecordNotFound:
Couldn't find Customer with 'id'=1 [WHERE (`customers`.`company_id` IS NOT NULL)   AND `customers`.`company_id` = ?]
    # ./app/controllers/customers/accounts_controller.rb:87:in `set_customer'
    # ./spec/support/engine_controller.rb:25:in `process_action'
    # ./spec/support/engine_controller.rb:3:in `get'
    # ./spec/controllers/customers/accounts_controller_spec.rb:21:in `block (3 levels) in <top (required)>'

我不确定customer.company_id = ?的含义， - 如果我这样做：

puts @customer.inspect

我得到以下输出：

#<Customer id: 2, user_id: nil, title: nil, first_name: "John", last_name: "Kusu", created_at: "2015-04-27 18:42:00", updated_at: "2015-04-27 18:42:00", deleted_at: nil, company_name: nil, company_id: 6>

据我所知，company_id已定义并设为6.我不知道为什么会收到此错误？

您正在引用未正确设置的一对多关系。

  def set_customer
    @customer = current_member.company.customers.find(params[:customer_id])
  end

此代码声明current_member属于拥有许多客户的公司。属于该公司的客户，请返回具有此ID的客户。

要实现此目的，您的customers表需要有一个名为company_id的外键。查看数据库迁移和this Rails guide。

还要将belongs_to添加到您的Customer类（首先执行此操作！并进行测试。这可能就是您所需要的。）

class Customers::AccountsController < ApplicationController
  before_action :set_customer
  belongs_to :company
