Rails創建不永久保存

我有一個軌3.2.13，postgres，紅寶石1.9.3應用程序，並遇到一個問題時，對象似乎暫時保存，然後消失。Rails創建不永久保存

在我的rails控制檯，我做了以下內容：

s = Shop.create(name: "my shop", city:"NY", state: "NY", user_id: 2) 
(0.4ms) BEGIN 
SQL (1.0ms) INSERT INTO "shops" ("about", "address1", "address2", "city", "created_at", "image", "name", "state", "stripe_shop_token", "updated_at", "user_id", "zip") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12) RETURNING "id" [["about", nil], ["address1", nil], ["address2", nil], ["city", "NY"], ["created_at", Tue, 09 Jul 2013 18:39:40 UTC +00:00], ["image", nil], ["name", "my shop"], ["state", "NY"], ["stripe_shop_token", nil], ["updated_at", Tue, 09 Jul 2013 18:39:40 UTC +00:00], ["user_id", 2], ["zip", nil]] 
(0.6ms) COMMIT 
=> #<Shop id: 46, user_id: 2, name: "my shop", address1: nil, address2: nil, city: "NY", state: "NY", zip: nil, about: nil, image: nil, stripe_shop_token: nil, created_at: "2013-07-09 18:39:40", updated_at: "2013-07-09 18:39:40"> 

Shop.all 
Shop Load (1.0ms) SELECT "shops".* FROM "shops" 
=> [#<Shop id: 46, user_id: 2, name: "my shop", address1: nil, address2: nil, city: "NY", state: "NY", zip: nil, about: nil, image: nil, stripe_shop_token: nil, created_at: "2013-07-09 18:39:40", updated_at: "2013-07-09 18:39:40">]

店鋪出現在控制檯中進行保存。我關閉了我的電腦，然後能夠在控制檯中恢復商店。如果我重新啓動應用程序，該商店似乎仍然可以識別，但是一旦我在應用程序中執行了任何操作，它就不能再找到該商店。如果我直接進入商店視圖，它會顯示商店，直到我更換頁面，然後再找不到商店。

下面是一些服務器日誌文件：

我如此堅持，我甚至不能確定什麼樣的信息將是有益的。

你覺得在服務器日誌查詢頁面變化過程中刪除的店？ – usha

我添加了服務器日誌，我看到了刪除，它看起來是在它渲染頁腳之前，這是否意味着與頁腳代碼相關，還是將它綁定到以前的渲染？ – Steve

@Vimsha，我想我所需要的只是讓你指出顯而易見的事情，那就是我有過的頁腳助手，如果current_user.shop = 0，我有'<如果current_user.shop = nil％>'而不是'<％ =無％>' – Steve

你可能會重寫數據user_id=2可能有。嘗試使用不同的user_id s創建多個記錄，看看會發生什麼。我認爲user_id可能是您的表格中的一個索引，這意味着當您使用user_id=2保存記錄時，您正在撰寫它。

嘗試：

s = Shop.new(name: "my shop", city:"NY", state: "NY", user_id: 2) 
s.save
