推荐答案

我有一个博客，我想在其中显示最新帖子、最新评论的列表, 在单个视图中发布类别.我怎么能做到这一点?我可以强烈地将我的视图输入到任何一个模型中，对吗?出现了视图模型.

I've a blog where I want to display the list of the latest posts, latest comments, post categories in a single view. How I can do that? I can strongly type my view to any one of the model right? There comes view model.

我创建了一个名为 BlogViewModel 的视图模型，其中包含最新帖子、最新评论和其他内容作为属性，并将我的视图与此模型绑定.posts、comments.. 是域模型，而 BlogViewModel 是视图模型 我专门为视图创建的.

I created a view model called BlogViewModel that contains latest posts, latest comments and other stuff as properties and I bind my view with this model. The posts, comments.. are domain models while the BlogViewModel is the view model I created specially for the view.

明天我将在移动版本中展示我的博客，届时我可能会创建一个仅包含较少属性的简单视图模型.最后.. 视图模型用于视图，大多数时候它们充当真实域模型的包装器！

Tomorrow I'll show my blog in a mobile version and at that time I may create a simple view model that contains only less properties. Finally.. view models are for views and most of the times they acts as wrappers over the real domain models!
