“渲染@collection"是什么意思?做? [英] What does "render @collection" do?

问题描述

我试图通过查看示例应用程序来更好地学习 Rails，同时查看 railscasts.com 来源的这一行，我注意到它是这样做的:

<%=渲染@episodes %>

这里到底发生了什么?为什么这没有记录在渲染函数中?或者是吗?

解决方案

This is shorthand for

render :partial =>"情节", :collection =>@episodes

上面的表单记录在 Rails API 文档 下的 render (ActionController::Base).除了 Rails Guides 外，就我所见，速记形式没有记录.>

I'm trying to learn Rails better by looking at example applications, and while looking at this line of the source of railscasts.com, I noticed it does this:

<div class="episodes">
    <%= render @episodes %>
  </div>

What exactly is going on here? Why isn't this documented on the render function? Or is it?

解决方案

This is shorthand for

render :partial => "episode", :collection => @episodes

The form above is documented in the Rails API docs under render (ActionController::Base). The shorthand form is not documented as far as I can see except in the Rails Guides.
