这是code业务逻辑或presentation逻辑是什么？ [英] Is this code business logic or presentation logic?

问题描述

这code在视图中存在：

This code exists in a View:

       if (Model.Group.IsPremium && null != Model.Group.ContactInfo)
       {
           Html.RenderPartial("ContactInfo", Model.Group.ContactInfo);
       }

乍一看，这是presentation逻辑所以没关系。但它不是我坐好。

at first glance, it's presentation logic and so it's ok. But it's not sitting well with me.

问题是，如果组被分类为premium，这意味着他们支付它的业务要求，以显示联系人信息。

The thing is, it's a business requirement to display contact info if the group is classified as premium, which means they paid.

你们觉得呢？如果这种逻辑被转移到一个或者的HtmlHelper通过其他方法抽象出来？或者这是查看的预期使用情况如何？什么是做这个code的最好的事情？

What do you guys think? Should this logic be moved into a HtmlHelper or abstracted away by some other means? Or is this the intended usage of the View? What's the best thing to do with this code?

推荐答案

我产生封装此逻辑为布尔DisplayContactInfo属性视图模型。这取决于你如何干净想你的意见。

I'd produce a ViewModel that encapsulates this logic as a boolean DisplayContactInfo property. It depends on how "clean" you want your views.
