• 如何在rails html.erb文件中注释行？ [重复] 3个答案

I understand that commenting in rails is done with '#' but if I try to comment out ERB tags, I always run into problems

我知道在rails中的注释是用'＃'完成的，但是如果我试着注释掉ERB标签，我总会遇到问题

 <%= link_to "Make default", make_default_admin_state_path(state) %>

Where would you put the '#' on this code?

你会在这里把'＃'放在这个代码上？

I tried to put it outside the <% and it did nothing. when I put it inside, there was an error message

我试图把它放在<％之外，它没有做任何事情。当我把它放在里面时，有一个错误信息

4 个解决方案

#1

<%#= link_to "Make default", make_default_admin_state_path(state) %>

<%# %> is an ERB comment: the dangling = makes no difference, and can be left in.

<％＃％>是一个ERB评论：悬空=没有区别，可以留下来。

#2

Just now I wanted to just leave a block out of the template because it was currently useless, if that's the case I suggest:

刚才我想把一个块从模板中删除，因为它目前是无用的，如果是这样，我建议：

<% if false %>
  this block of code won't give runtime errors..
  <%= alm lkjsxajklla 10293 aslkj no problems! %>
<% end %>

#3

<!-- %= link_to "Make default", make_default_admin_state_path(state) % --> 

#4

you can do it like one the @Dominic Goet did.If you stuck from it you can try this one

你可以像@Dominic Goet那样做。如果你坚持下去就可以尝试这个

<%=# link_to "Make default", make_default_admin_state_path(state) % >

or

要么

< %#= link_to "Make default", make_default_admin_state_path(state) %>
