Ruby on Rails中的控制器类应包含什么？

[英]What should a controller class in Ruby on Rails contain?

原文 2012-02-06 07:14:19 8 2 ruby-on-rails/ ruby

I am making a quiz web application so there is a need to administrate questions (add, change etc) and the users will browse the collection and possible add, report etc questions. 我正在制作一个测验Web应用程序，因此需要管理问题（添加，更改等），并且用户将浏览集合并可能添加，报告等问题。

Now, if I made a questioncontroller would this contain all actions(methods) for dealing with questions (both public and admin) or is this a case where you make two controllers? 现在，如果我创建了一个questioncontroller，它将包含所有用于处理问题（公共和管理员）的操作（方法），还是您要创建两个控制器的情况？

Could someone explain when I should make new controllers instead of just adding actions to one existing? 有人可以解释我何时应该制作新的控制器，而不仅仅是在现有控制器上添加操作？

And if I made two controllers, I would end up duplicating a lot of code. 而且，如果我制造了两个控制器，最终将导致重复很多代码。 Should I make a base class? 我应该做基础课吗？

2 个解决方案

You could build everything using a single controller. 您可以使用单个控制器来构建所有内容。 I think using multiple controllers is something related to the project structure. 我认为使用多个控制器与项目结构有关。

In your case I would implement all kind of questions in the same controller (named "questions_controller.rb", for example), and inside I would implement a filter to authenticate admin users when requesting admin questions. 在您的情况下，我将在同一个控制器中（例如，名为“ questions_controller.rb”）实施所有类型的问题，而在内部，我将实施过滤器以在请求管理员问题时对管理员用户进行身份验证。

It's very probable that you will need other controllers for your app, such as static pages (contact, about), sessions (login, logout), members (register, profile), etc. 您的应用很可能需要其他控制器，例如静态页面（联系，关于），会话（登录，注销），成员（注册，个人资料）等。

About the base class, sure! 关于基类，当然！ If you are repeating methods it would be a nice solution. 如果您要重复方法，那将是一个不错的解决方案。 Rails is just Ruby. Rails只是Ruby。

It's not neccessay to create two controller, if you considered administrator as normal users. 如果您将管理员视为普通用户，则不必创建两个控制器。 If you need a special user to administrate the questions as admin, Creating two controllers is needed! 如果需要特殊用户以管理员身份管理问题，则需要创建两个控制器！

That's my options. 那是我的选择。 Hope can help you! 希望可以帮到您！
