Rails:渲染模型? [英] Rails: Rendering Models?

问题描述

我可以想到一百万种在 Rails 中渲染模型的非自动方法，但我想知道是否有一些内置方法可以做到这一点.我希望能够做到这一点

I can think of a million not-so-automatic ways to render a model in Rails, but I'm wondering if there's some built-in way to do it. I'd like to be able to this

<%=@thing -%>

很明显，你可以用局部来做到这一点(我的意思是，调用 render :partial)，但我想知道是否有一些标准的方法可以将视图与模型关联.

obviously with partials you can do it (I mean, calling render :partial), but I'm wondering if there's some standard way to associate views with models.

推荐答案

如果直接将模型传递给 render 它将尝试为其渲染部分.

If you pass a model directly to render it will attempt to render a partial for it.

<%= render @thing %>

那是一样的.

<%= render :partial => 'things/thing', :object => @thing %>

如果你传递一个模型数组...

If you pass an array of models...

<%= render @things %>

它将为每个渲染 _thing 部分，就像你这样做一样.

It will render the _thing partial for each as if you did this.

<%= render :partial => 'things/thing', :collection => @things %>

注意:这需要 Rails 2.3.如果您有早期版本的 Rails，则需要使用 :partial 选项来做同样的事情.

Note: this requires Rails 2.3. If you have earlier versions of Rails you'll need to use the :partial option to do the same thing.

<%= render :partial => @thing %>
