Just adopted an application using HAML and trying to write on top of it (never used HAML before). Been looking at different resources like haml.info and this SO post . However, the SO post is actually incorrect in a couple ways. I'm trying to render your basic bootstrap flash messages.
So far I have this structure:
- flash.each do |key, value|
.alert.alert-dismissable{ :class => 'alert-#{key}' }
%button.close{ :type => 'button', :data => { :dismiss => 'alert' }, :aria => { :hidden => 'true' } }
%i.icon-remove-sign
= value
Yea that's right, I have to go back to Bootstrap 2 on this one. Seems like everything works, except this line here:
.alert.alert-dismissable{ :class => 'alert-#{key}' }
This gets rendered to HTML as
<div class="alert alert-#{key} alert-dismissable">
Obviously, I want #{key}
to be replaced with the key coming from the controller ( success
, danger
, notice
, etc) Would love to know what is wrong here. Thanks for taking a look at it.
"alert-#{key}"
在ruby中,您无法使用#{}
来转义单引号字符串。
