Nit*_*arg 12 session ruby-on-rails marshalling
我的应用程序需要在会话中保留大型数据对象.通过解析包含具有3-4个字符串的150个X 20个单元的csv,每个数据对象有3-4个.我的应用程序显示此错误 - "编组数据太短".我试过这个 -
rake db:sessions:create. text: data为longtext: data.rake db:migrate.申请的其他细节 -
在视图"index.html.erb"中 - 有一个链接对控制器中的操作进行ajax调用,该操作解析大型csv文件并从中生成一个对象.此对象存储在会话中.

我遇到了完全相同的问题.
我的Rails版本是4.1.4.
我通过运行解决了这个问题:
rake tmp:clear
从tmp /中清除会话,缓存和套接字文件(窄w/tmp:sessions:clear,tmp:cache:clear,tmp:sockets:clear)
您也可以使用限制执行迁移,而不是手动ALTER TABLE,如下所示:
class FixSessionStore < ActiveRecord::Migration
def self.up
change_column :sessions, :data, :text, :limit => 4.megabytes
end
def self.down
end
end
这会将列转换为MEDIUMTEXT,并在schema.rb中正确显示.
在Rails 4开发模式中,我遇到了同样的错误,解决方案如下:
从/ tmp/cache/assets文件夹中删除所有缓存文件.
(不幸的是rake资产:干净只是没有解决这个问题.)
访问出现该错误的页面后,错误日志中会显示什么？
另外,MySQL中会话信息的列类型是什么？文本？
-------------以下编辑----------------
好吧,据我所知,这个错误通常意味着你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,看看它是否给你任何改进:
ALTER TABLE sessions CHANGE COLUMN data data LONGTEXT
显而易见的解决方案是不将CSV数据存储在会话中,因为这可能不是放置它的最佳位置,但我不知道你背后所做的原因,所以也许你没有其他选择.
尝试一下,让我知道它是否有效.
