ruby-on-rails – 组织数据太短

我的应用程序需要保留大型数据对象在会话中.这里有3-4个数据对象,每个对象都是通过解析包含150个X 20单元格的csv来创建的,这些单元格具有3-4个字符的字符串.
我的应用程序显示此错误 – “组织数据太短”.
我试过这个 –

>删除旧会话表.
>删除会话表的旧迁移.
>使用rake db创建新的迁移：sessions：create.
>手动编辑迁移,将文本：数据更改为longtext：data.
>使用rake db：migrate运行迁移.

其他应用细节 –

在视图“index.html.erb” – 有一个链接,使ajax调用控制器中的一个动作,该操作解析大型csv文件,并使一个对象脱离它.该对象存储在会话中.

解决方法

访问提供该错误的页面后,错误日志中显示什么？

此外,MysqL中的会话信息的列类型是什么？文本？

————-以下编辑—————-

好的,只要我能够确定,这个错误通常意味着您在会话中推送的内容的大小对于MysqL列来说太大了.引用的最常见的解决方案似乎指向将列从TEXT更改为LONGTEXT的解决方案.

尝试在MysqL中运行这样的东西,看看它是否可以改进：

ALTER TABLE sessions CHANGE COLUMN data data LONGTEXT

明显的解决方案是不将CSV数据存储在会话中,因为这可能不是最好的地方,但我不知道你在做什么的原因,所以也许你没有其他选择.

尝试一下,让我知道如果它有效.
