simple_form提示作为工具提示

Question

我试图将我的simple_form提示显示为twitter-bootstrap工具提示，以便仅在用户选择输入字段或将其悬停在其上时显示提示。

表单项看起来像（以haml为单位）：

:ruby 
  title = <<TITLE
    This text is normally hidden and pops up as a bootstrap tooltip 
    only when the user hovers on the input field.
  TITLE
= f.input :opt_out, hint: title 

我的用于simple_form提示的CSS和Javascript很普通，所以我认为我必须修改config/initializers/simple_form.rb初始化程序文件：

b.use :hint,  :wrap_with => { :tag => :span, :class => :hint }

Answer 1

我是这样解决的：

    :ruby 
      title = <<TIT 
        This text is normally hidden and pops up as a bootstrap tooltip 
only when the user hovers on the input field.
      TIT
      link = link_to "what's this?", "", rel: "tooltip", title: title, data: {placement: "right"}
      label = "Opt out #{link}"
    = f.input :opt_out, label: raw(label)
