Question

我在Company

下有一个名为模型的模型

class Company::Employee

我有一个控制器，用于我的员工的个人资料，在Employee

下命名

class Employee::ProfilesController < EmployeeController

我在该控制器中设置@employee

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

但我有错误

未定义的方法`find'for Employee：Module

似乎Company::Employee已解析为托管Employee的{{1}}模块。

当我在那里看到时，我有一条额外的消息Employee::ProfilesController。如何通过模型类引用控制器模块？

我尝试了一些内容，包括warning: toplevel constant Employee referenced by Company::Employee和::Company::Employee，但没有任何变化。

相关文件位于

require 'company/employee'
app/controllers/employee/profiles_controller.rb

微量

app/models/company/employee.rb

类

NoMethodError (undefined method `find' for Employee:Module):

我发现this nice article解释了自动加载可能是一团糟。

我仍然不确定为什么在我的特定情况下会发生此错误，但有些评论指出require_dependency可以帮助我，并且确实如此：

在我的Company::Employee控制器上添加这两行之后，一切似乎都运行良好

（请注意，我还需要添加第二个，或者我得到NoMethodError (undefined method 'where' for Company:Class):

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

从Bar :: BazController调用Foo :: Bar
