我需要在SimpleForm生成的标签中添加额外的span。 目标是能够使用this coffeescript来验证现场存在。
目前它看起来像：
<div class="control-group form-group string optional dealer_website">
<label class="string optional control-label" for="dealer_website">
Website
</label>
<div class="controls">
<input class="string optional form-control" id="dealer_website" name="dealer[website]" size="50" type="text">
</div>
</div>
我需要它看起来像：
<div class="control-group form-group string optional dealer_website">
<label class="string optional control-label" for="dealer_website">
Website
<span class="error-message"></span>
</label>
<div class="controls">
<input class="string optional form-control" id="dealer_website" name="dealer[website]" size="50" type="text">
</div>
</div>
这是我的simple_form_bootstrap.rb
