ruby-on-rails - Bind '.error' class to manually created haml wrapper

Question

I have next group of controls:

.control-group.string.required.user_name
  = f.input_field :name, required: true, class: 'form-control'
  = f.label 'User Name'
  = f.error :name

Is there any way to bind '.control-group' to it's child input, so if input is invalid, wrapper will get class ".error" added?

Thanks

我为此创建了一个自定义组件，如下所示

config.wrappers :perfect_forms, tag: 'div', class: 'control-group', required: true, error_class: 'error' do |b|
  b.use :html5
  b.use :input, class: 'fotm-control', required: true
  b.use :label
  b.use :error, wrap_with: { tag: 'span', class: 'help-inline' }
end

现在有一个问题，是否可以检测此配置中的输入类型？因为目前要明确设置输入的类型，所以我正在为所需的输入编写“input_html: { type: 'text'}”，但是在包装器配置中处理这种情况会很棒。就像类型是“电子邮件”一样 - 然后插入类型“文本”。
