如何评论Rails视图中的代码？ [英] How to comment code in Rails views?

问题描述

当我使用Rails和开发视图时，我经常想注释掉代码。简单足够与类&模型，但观看次数有点棘手。

As I'm playing with Rails and developing views I often want to comment out code. Simple enough with classes & models but views are a bit more tricky.

在视图中注释代码的最佳方法是，它不会被解释，好吧，任何东西... HTML给我们<！ - 评论Rails代码在这里 - > 虽然这里的代码似乎解释了吗？还是有更多的Railsy方式？

What's best way to comment code in a view so it's not interpreted by, well, anything... HTML gives us <!-- commented Rails code here --> though code enclosed here seems to get interpreted anyway?!? Or is there a more Railsy way?

推荐答案

<％code code＃comment％> USED工作，偶然。

<% code code # comment %> USED to work but I think that was accidental.

您始终应在单独的注释标签中注释注释<％＃comment％>

You were always supposed to put comments in separate comment tags <%# comment %>

注释

现在，旧的漏洞被关闭了（我忘记'now'是指Ruby 1.8还是Rails 3或者什么），所以：

Now the old loophole is closed (I forget whether 'now' means Ruby 1.8 or Rails 3 or what) so that:

<％code code＃this runs too％>
<％＃也运行％>
<％＃注释掉的唯一方法％>

<% code code # this runs too %> <% # also runs %> <%# the only way to comment out %>
