在ASP.NET MVC新闻栏目 [英] News section with ASP.NET MVC

问题描述

我开发了一个新闻页面在ASP.NET MVC和它的URL为本地主机/新闻网站。
为此，我公司开发的控制器，型号，以及遍历模型中的所有项目和一个视图显示它们。
此页面显示数据库中可用递减日期顺序排列的所有新闻。
我用路由新闻/ {ID}在细节显示特定的消息。

I have developed a news page for a website in ASP.NET MVC and its URL being localhost/News. For this purpose I have developed a controller, model, and a view that iterates over all items in a model and displays them. This page displays all the News available in database in descending order of date. I have used routing News/{id} for displaying that particular news in details.

我应该怎么做，如果我想显示说我主页上只剩下最后5新闻帖子？
可在控制器重复使用？或者，我需要重写code从我的数据库中获取新闻的记录？

What should I do, if I want to display say only last 5 news posts on my home page? Can the controller be reused? Or I'll need to rewrite the code for fetching news records from my database?

推荐答案

我最近有pretty很多同样的问题。我已经结束了使用MVC期货实行的RenderAction。一个很好的例子，说明如何使用它是在这里：

I recently had pretty much the same question. I've ended up using MVC Futures RenderAction implementation. A good example explaining how to use it is here:

基本上，你必须在你的ArticleController这样的事情（我不叫我的NewsController只是因为我疑神疑鬼假设新闻报的类型是新的集合：P）...

Basically you'd have something like this in your ArticleController (I don't call mine "NewsController" simply because I'm paranoid about it assuming "News" is a collection of type "New" :P)...

public ActionResult SidebarBox()
{
// I use a repository pattern to get records, just replace it with whatever you use
// also replace *.Take(5)* with however many you want returned
return View(repoArticles.GetAllArticles().Take(5).ToList());
}

和您的母版页（或任何你想要显示它），你会使用：

and in your Master Page (or wherever you want to display it) you'd use:

<% Html.RenderAction<ArticleController>(c => c.SidebarBox()); %> 

然后与刚刚code你的边栏视图。

Then have a view with just the code for your sidebar box.
