调用foo ::酒吧从酒吧:: BazController

-1

我有一个模型下Company调用foo ::酒吧从酒吧:: BazController

class Company::Employee

我对我的员工的轮廓控制器命名空间，Employee

class Employee::ProfilesController < EmployeeController

我设置的命名空间下@employee在那个控制器里

@employee = Company::Employee.find(...)

但是我有错误

未定义的方法`发现”的员工：模块

似乎Company::Employee解析为承载Employee::ProfilesController的Employee模块。

当我在byebug那里，我有一个额外的消息warning: toplevel constant Employee referenced by Company::Employee。模型类如何引用控制器模块？

我尝试了一些东西，包括::Company::Employee和require 'company/employee'，但没有任何变化。

有问题的文件是在

app/controllers/employee/profiles_controller.rb
app/models/company/employee.rb

跟踪

显示完整的类和与第n行的全部错误信息umbers。 – smathy

在这里，你去。我的自定义模块很可能与问题无关，他们只是添加一些字段和委托的东西与ActiveSupport :: Concern –

什么玩笑，如果我之前执行一行，需要好的类通过其他协会，如' Company.first.employees.first.class'，它实际上解决了这个问题。但是，只要我删除此行，它就会停止工作。如果任何人都可以解释... –

我发现this nice article可以是一团糟。

我仍然不知道为什么这个错误在我的特定情况下发生，但一些评论人士指出，require_dependency可以帮助我和它没有：

我Company::Employee控制器的顶部添加这些2行后，一切似乎是工作的罚款

（请注意，我也很需要添加第二个或我会得到一个NoMethodError (undefined method 'where' for Company:Class):

# app/controllers/company/profiles_controller.rb 
require_dependency "company/employee.rb" 
require_dependency "company.rb"
