数据绑定从根本上与MVC不兼容吗? [英] Is data binding fundamentally incompatible with MVC?

问题描述

数据绑定在视图和模型之间建立直接耦合，从而绕过了控制器.从根本上讲，这与Model-View Controller的架构模式不符，我是否正确地考虑了这一点?这会使数据绑定成为坏事"吗?

Data binding establishes a direct coupling between the view and the model, thereby bypassing the controller. Fundamentally this breaks with the Model-View Controller architectural pattern, am I right in thinking this? Does this make data binding a "bad thing"?

编辑:例如， angular 声称是MVC框架，但还是其中之一它的主要功能是数据绑定.

As example, angular claims to be a MVC framework, yet one of its main features is data binding.

推荐答案

不一定，因为您不必将Model对象绑定到视图.
我通常要做的是创建简单的DTO(或演示对象)，这些DTO仅包含我要显示的数据，这就是View层显示的内容.
在那种情况下，控制器保留其在DTO上执行的操作与基础Model实体上的操作之间的翻译器功能.

Not necessarily, since you don't have to bind your Model objects to the view.
What I usually do is create simple DTOs (or Presentation Objects) that contain only the data I want to display, and that's what the View layer displays.
In that case, the Controller retains its function as a translator between actions performed on the DTOs and actions on the underlying Model entities.
