Ruby on rails 3 Rails 3.1，为什么是简单的u型&x27；s包装器_标记未按预期工作？

当我以简单的形式使用wrapper_标记时，它在开发模式下运行良好，但是当我将应用程序部署到heroku时，呈现的结果是不同的

我使用

wrapper\u标记

如下：

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

请注意生产中的结果：（：div被用来代替：p）

课程ID
*头衔
*description仅用于测试，以查看checkeditor的预编译资产是否正常工作。。
学分输入零以禁用课程学分
目录中的列表
验证码
顺序章节存取

在开发模式中，is工作正常：（使用标记：p）

课程ID
*标题
*说明这是一门很酷的课程
学分输入零以禁用课程学分
目录中的列表

验证代码

连续章节访问

这里有我遗漏的东西吗？我应该检查什么？

它可能与开发与生产中的类缓存有关

如果要全局更改

wrapper\u标记

，应在

simple\u表单

初始值设定项中执行。如果要逐个字段进行更改，可以将

wrapper\u标记

选项传递给

input
