Rails 3.1，为什么simple_form的wrapper_tag不能按预期工作？

Question

当我在simple_form中使用wrapper_tag时，它在开发模式下工作正常，但是当我将应用程序部署到heroku时，渲染结果不同。

我使用wrapper_tag这样的：

<%- SimpleForm.wrapper_tag = :p -%> 

通知结果制作：（：DIV来代替：P）

<form accept-charset="UTF-8" action="/courses/1" class="simple_form edit_course" id="edit_course_1" method="post"> 
<div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="+qH0C/hOaatVnw+Jp2vysanyG5tSB6E6gayIGlJCYbo=" /></div> 

<div class="input string optional"><label class="string optional" for="course_course_id"> Course ID</label><input class="string optional" id="course_course_id" maxlength="255" name="course[course_id]" size="50" type="text" value="" /></div> 

<div class="input string required"><label class="string required" for="course_name"><abbr title="required">*</abbr> Title</label><input class="string required" id="course_name" maxlength="255" name="course[name]" required="required" size="50" type="text" value="This is my first course here at clouds!!" /></div>

<div class="input boolean optional"><input name="course[list_in_catalog]" type="hidden" value="0" /><input checked="checked" class="boolean optional" id="course_list_in_catalog" name="course[list_in_catalog]" type="checkbox" value="1" /><label class="boolean optional" for="course_list_in_catalog"> List in catalog</label></div> 

<div class="input string optional"><label class="string optional" for="course_validation_code"> Validation code</label><input class="string optional" id="course_validation_code" maxlength="255" name="course[validation_code]" size="50" type="text" value="" /></div>

</form> 

在开发模式

是正常工作：（标签：使用p）

<form accept-charset="UTF-8" action="/courses/13" class="simple_form course" id="edit_course_13" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="_method" type="hidden" value="put" /><input name="authenticity_token" type="hidden" value="eOi8hkGQ8eoZYwzIQBcBEB66ekI9kTTYztsyU+UKzmQ=" /></div>

<p class="input string optional"><label class="string optional" for="course_validation_code"> Validation code</label><input class="string optional" id="course_validation_code" maxlength="255" name="course[validation_code]" size="50" type="text" value="" /></p> 

<p class="input boolean optional"><input name="course[sequential_chapter_access]" type="hidden" value="0" /><input class="boolean optional" id="course_sequential_chapter_access" name="course[sequential_chapter_access]" type="checkbox" value="1" /><label class="boolean optional" for="course_sequential_chapter_access"> Sequential chapter access</label></p> 

</form> 

有没有什么我在这里失踪？我应该检查什么？

它可能有事情做与类缓存在开发与生产。

如果要全局更改wrapper_tag，应该在simple_form初始值设定项中执行此操作。如果您想要逐字段地更改它，您可以将wrapper_tag选项传递给input调用。
