导轨 - 自定义HTML成simple_form标签 [英] Rails - Custom html into simple_form label

问题描述

我想定制simple_form协会的输出，基本上我需要在两行显示一个复选框标签。我的想法是增加一个BR标签进入标签，但不幸的是它被逃脱，因此实际显示BR而不是去一个新行

I'm trying to customize the output of a simple_form association, basically I need to display a checkbox label on two lines. My idea was adding a "br" tag into the "label", but unfortunately it gets escaped so it display actually "br" instead of going to a new line

我使用lambda定制标签输出

I use a lambda for customizing the label output

<%= f.association :item, :as => :check_boxes, :collection => current_user.items, :label => false, :label_method => lambda { |item| "#{item.city.capitalize},<br> #{item.address}" }%>

这会产生逃脱BR标签字符串中，我怎么能显示两行的标签？

this produces an escaped br into the label string, how could I display the label on two lines?

推荐答案

通话 html_safe 你想要的字符串方法不被转义。

call html_safe method on the string you want not to be escaped.

<%= f.association :item, :as => :check_boxes, :collection => current_user.items, :label => false, :label_method => lambda { |item| "#{item.city.capitalize},<br> #{item.address}".html_safe }%>
