Postgres 还是database_cleaner？

Question

我遇到了一个非常奇怪的案例。我有这种情况，有时它会过去。有时则不然。事实上，每个步骤都是绿色的，但是在该步骤之后它会生成这个垃圾堆栈跟踪，它不会告诉我有关我的应用程序的任何信息。

我在这里并没有做任何复杂的事情，只是想用 TinyMCE 创建一个该死的评论。我还有 20 个其他场景，其中一些要复杂得多。

它可能有助于说明我的环境，尽管从堆栈跟踪中非常明显：

Rails 3.1、ruby 1.9.2、所有内容的最新“稳定”版本。 Postgres 9.0.4。

有比我聪明的人能解释一下为什么我会遇到这个问题吗？

当我运行时，我收到了资产管道和tiny_mce的类似问题

rake assets:precompile

...我尝试使用 iconv 等转换文件 editor_plugin_src.js 和 editor_plugin.js ，但最终只是暂时删除它们，一切正常。我正计划“正确修复它”，但如果您不需要拼写检查器，则可能不需要这些文件......
