元帥數據太短

我的應用程序需要保持會話中的大數據對象。有3-4個數據對象，每個數據對象都是通過解析包含150個包含3-4個字符的字符串的150 X 20個單元格的csv創建的。 我的應用程序顯示這個錯誤 - 「元帥數據太短」。 我試過了 -元帥數據太短

  • 刪除舊的會話表。
  • 刪除會話表的舊遷移。
  • 使用rake db:sessions:create創建新遷移。
  • 手動編輯遷移，將text: data更改爲longtext: data。
  • 使用rake db:migrate運行遷移。 application--

    鑑於「index.html.erb」的

其他細節 - 有使AJAX調用，以在控制器的動作的鏈路，該操作解析大csv文件和使對象出來了。這個對象存儲在會話中。

顯示的內容在錯誤日誌您訪問給出了錯誤頁面後？

另外，MySQL中會話信息的列類型是什麼？文本？

-------------編輯下面----------------

好，據我已經能夠確定，這個錯誤通常意味着你在會話中推送的內容的大小對於MySQL列來說太大了。引用的最常見解決方案似乎指向將文本列從TEXT更改爲LONGTEXT的解決方案。

嘗試在MySQL運行這樣的，看看它是否給你任何改善：

ALTER TABLE sessions CHANGE COLUMN data data LONGTEXT

顯而易見的解決方案是不是CSV數據存儲在會話這可能不把它最好的地方，但我不知道你背後的原因，所以也許你沒有別的選擇。

試一下，讓我知道它是否有效。

取而代之的是手動ALTER TABLE，你也可以做一個遷移有限制，像這樣：

class FixSessionStore < ActiveRecord::Migration 
    def self.up 
    change_column :sessions, :data, :text, :limit => 4.megabytes 
    end 

    def self.down 
    end 
end

這將轉列到MEDIUMTEXT，並在您的schema.rb正確顯示。

以前的解決方案並不適合我。什麼做的工作對我來說是清除會話的緩存與

rake db:sessions:clear

這需要做疏通延長session.data列的大小之前創建腐敗會議。 MySQL默默截斷。 – 2013-04-11 00:46:45

在Rails 4的開發模式我有同樣的錯誤，將溶液如下：

刪除的/ tmp /緩存/所有的緩存文件資產文件夾。

（不幸的是耙資產：潔淨只是還沒有解決這個問題。）

我遇到了完全一樣的問題。

我的Rails版本是4.1.4。

rake tmp:clear

清除會話，緩存和套接字文件從TMP /（窄W/tmp目錄：會話：清晰，TMP：緩存：清晰，TMP：插座：

我通過運行解決了這個問題明確）

rm -rf tmp/cache
