如何在erb模板中发表评论？ [英] How does one comment in an erb template?

问题描述

我有一些琐碎的标记，如下所示：

I have some trivial markup that looks like the following:

<li class="someclass">
  <=% t'model.attr' %>
</li>

有没有简单的方法可以对此进行评论？仅将<！--> 包裹在该块周围，仍将红宝石代码保留给模板使用。这意味着我必须分别注释掉HTML和Ruby特定的代码。

Is there a trivial way to comment that out? Just wrapping <!-- --> around the block will still leave the ruby code available to the template. This means I have to comment out the HTML and Ruby specific code separately.

用最少的标记注释掉所有三行的最佳方法是什么？

What's the best way to comment out all three lines with the least amount of markup?

推荐答案

=开始和 = end 是块注释的Ruby版本。

=begin and =end are the Ruby version of block comments.

在erb模板中使用它们：

Using them in an erb template:

<%
=begin
%>
<li class="someclass">
  <=% t'model.attr' %>
</li>
<%
=end
%>
