Rails:我应该如何在控制器之间共享逻辑? [英] Rails: how should I share logic between controllers?

问题描述

这个问题肯定已经有人问过了，但我找不到.

This question must have been asked already, but I can't find it.

我有一个 UsersController 和一个 Admin::UsersController.显然，这些类中发生的很多事情(例如，strong_parameters 的实现，创建/编辑用户后要遵循的路径)是相同的.

I have a UsersController and an Admin::UsersController. Obviously a lot of what goes on in these classes (eg the implementation of strong_parameters, the paths to follow after creating/editing a user) are the same.

我可以 - 确实，应该吗?- 在这些控制器之间共享代码?这是担心的原因吗?我在网上为他们找到的例子倾向于处理模型.

Can I - indeed, ought I? - share code between these controllers? Is this what concerns are for? The examples I find for them online tend to deal with models.

非常感谢任何指导.

推荐答案

使用关注点(放入app/controllers/concerns)

module UsersControllable
  extend ActiveSupport::Concern

  def new
  end

  def create
  end

  private
  def user_params
    # strong params implementation
  end
end

class UsersController < ApplicationController
  include UsersControllable
end

class Admin::UsersController < ApplicationController
  include UsersControllable
end
