实施＆QUOT;更多＆QUOT;在.NET MVC3 [英] Implementing "Read More" in .NET with MVC3

问题描述

我写在MVC3 .NET一个简单的博客应用程序，作为一个学习的过程。

I'm writing a simple "blog" application in .NET with MVC3, as a learning exercise.

要实现 - 基本的 - 更多的功能，我添加了一个自定义的按钮tiny_mce，当pressed，插入

To implement - rudimentary - "read more" functionality, I've added a custom button to tiny_mce which, when pressed, inserts

<!--#readmore#-->

进入后的内容。

这样做是为了获得内容到这一点，显示在主页上，然后添加一个链接，如果有更多的阅读，正如每一个博客引擎做如初。

The idea is to obtain the content up to that point to show on the homepage and then add a link if there's more to read, as done by every blog engine ever.

这样做是pretty简单，我有问题的其中的应该怎么办呢？现在，我已经在Post模型的功能：

Doing this is pretty straightforward, the question I have is where should I do it? Right now, I have the functionality in the Post model:

public String content_read_more()
    {
        if (this.content.Contains("<!--#readmore#-->"))
        {
            int position = this.content.IndexOf("<!--#readmore#-->");
             this.has_read_more = true; 
            return this.content.Substring(0, position);
        }
        else
        {
            this.has_read_more = false;
            return this.content;                 
        }
    }

我避免创建链接到模型中的完整的帖子，因为它似乎没有被什么东西模型应该做的。

I avoided creating the link to the complete post within the model, since it didn't seem to be something the Model should do.

但是，这样做那样，我要检查是否有后视图中的更多的内容：

But, doing it like that, I have to check if the post has more content in the view:

<div class="content">
    @Html.Raw(item.content_read_more())
    @if (item.hasReadMoreLink())
    {
        @Html.ActionLink("Leer más", "Details", new { id = item.id })
    }
</div>

它引入逻辑到视图中。

which introduces logic into the view.

我应该做的控制器？有没有更好的方式来做到这一点？我在想这样太辛苦？

Should I do it in the controller? Is there a better way to do this? Am I thinking about this way too hard?

感谢您！

推荐答案

这是完全正常的。结果
没有什么错在视图中添加简单的如果秒。

That's perfectly normal.
There is nothing wrong with adding simple ifs in the view.

您应避免添加的业务逻辑视图的;相反，你应该把它放在控制，并将结果发送到视图（完全按照你现在做的）。

You should avoid adding business logic in the view; instead, you should put it in the control and send the results to the view (exactly as you're doing now).
