我遇到一個問題，從新添加的列向我的mysql數據庫寫入信息。特別是'site_email'。當我在本地運行項目時，可以用向我的新列內容寫入數據庫，並顯示在隨後的顯示頁面上。Rails表單不能寫入數據庫
但是在dev服務器上我不行。開發服務器日誌顯示請求中發送的內容。
Started PUT "/sites/18" for x.x.139.147 at 2012-12-03 19:47:39 +0000
Processing by SitesController#update as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"6QXzdALrXqXoQz+Q5SFXd+egNQGxOAdNIC8ZH9A9yqU=", "site"=>{"customer_id"=>"1", "site_name"=>"Demohello", "site_domain"=>"Demo", "site_email"=>"[email protected]", "google_analytics_code"=>"", "visible"=>"1", "mobile_visible"=>"1", "logo_cache"=>"", "background_logo_cache"=>"", "header_cache"=>"", "background_cache"=>"", "campaign_wrapbar_cache"=>""}, "commit"=>"Update Site", "id"=>"18"}
Redirected to http://x.com/sites/18
Completed 302 Found in 17ms
但是當它進入顯示頁面時，新的/更新的電子郵件數據不存在。奇怪的是，如果我將任何數據添加到預先存在的列以及其他數據已成功發送到數據庫，但電子郵件不是。
索引顯示和編輯頁面全部顯示沒有錯誤，如果我手動更改數據庫中顯示在顯示頁面上的信息。由於發送請求數據並且頁面不會產生錯誤，所以我甚至完全沒有辦法進行調試。
在/ var /網絡/網站名稱/電流我跑
bundle exec rake db:migrate
使用SequelPro我可以看到，列看起來是有連接到開發數據庫，而事實上，如果我在site_email插入值列中的數據出現在顯示頁面上。插入值
DB
顯示頁面

UPDATE
不改變事物的價值寫信給數據庫。 24日左右。我現在與現場服務器有同樣的問題。我再等24小時，看看是否這樣排序問題，或者我不小心以其他方式解決問題。
萬一別人有這個問題在未來，沒有任何人有一個想法，爲什麼它的行爲可能以這種方式？
更新2
Live服務器現在更新值也是如此。這似乎是服務器可能負載很重或數據庫以某種方式播放。
參考
僅供參考，如果你試試在評論中所有建議，也看托馬斯的回答這樣就可以解決問題的所有情況下，99.9％。如果它在本地工作，但不在服務器上，並且您已經嘗試了所有這些步驟，那麼這可能與我遇到的問題相同，但不幸的是，目前我沒有真正的答案。
請出示您的控制器代碼.. – Lichtamberg
你遷移數據庫？添加了 – samullen
