Rails 3：使令牌输入可排序

Question

我在文本字段中使用令牌输入并希望使这些令牌可排序（JQuery UI）。我正在使用Ryan Bates screencast开始，但我不确定如何将content_for应用于我的代码。以下是我有...

<fieldset id="presenters"> 
    <p> 
    <%= event_form.label :presenter_tokens, "Presenters" %> 
    <%= event_form.text_field :presenter_tokens, "data-pre" => @event.presenter_tokens_tokeninput.to_json %> 
    </p> 
</fieldset> 

下面是HTML我得到...

<fieldset id="presenters"> 
<p> 
<label for="event_presenter_tokens">Presenters</label> 
<ul class="token-input-list-facebook"> 
<li class="token-input-token-facebook"> 
<p>Mark</p> 
<span class="token-input-delete-token-facebook">×</span> 
</li> 
<li class="token-input-token-facebook"> 
<p>Laurie</p> 
<span class="token-input-delete-token-facebook">×</span> 
</li> 
<li class="token-input-input-token-facebook"> 
</ul> 
<input data-pre="[{"id":131,"name":"Mark"},{"id":1311,"name":"Laurie"}]" id="event_presenter_tokens" name="event[presenter_tokens]" size="30" type="text" value="131,1311" style="display: none;"/>
