ruby-on-rails - marshal 数据太短

我的应用程序需要在 session 中保留大数据对象。有 3-4 个数据对象,每个对象都是通过解析包含 150 X 20 个单元格的 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 - “编码(marshal)数据太短”。
我试过这个-

  • 删除旧的 session 表。
  • 删除 session 表的旧迁移。
  • 使用 rake db:sessions:create 创建新的迁移.
  • 手动编辑迁移,更改 text: datalongtext: data .
  • 使用 rake db:migrate 运行迁移.

  • 其他申请详情--

    在 View “index.html.erb”中 - 有一个链接可以让 ajax 调用 Controller 中的 Action ,该 Action 解析大型 csv 文件并从中生成一个对象。这个对象存储在 session 中。

    最佳答案

    访问出现该错误的页面后,错误日志中会显示什么?

    另外,MySQL 中 session 信息的列类型是什么?文本?

    ------------- 在下面编辑 ----------------

    好的,据我所知,此错误通常意味着您在 session 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,看看它是否能给你带来任何改进:

    ALTER TABLE sessions CHANGE COLUMN data data LONGTEXT

    显而易见的解决方案是不在 session 中存储 CSV 数据,因为这可能不是放置它的最佳位置,但我不知道您所做的事情背后的原因,所以也许您没有其他选择。

    试一试,让我知道它是否有效。
