我已經扔在一起快速下來和骯髒的應用程序來跟蹤一些信息的臨時基礎。我知道,不要以明文形式存儲密碼。這不是面向公衆的,它是在一個極其安全的內部盒子上;沒有人能夠獲得它,頁面不可訪問,但只是一個簡短的列表。無論如何...我試圖弄清楚爲什麼當我編輯一條記錄時,更新將一個未經編輯的記錄字段保存爲空白,當從數據庫中讀取值時,該字段爲空。在這種情況下,我從索引視圖中選擇一條記錄。我編輯該記錄,而不是觸摸密碼字段。我保存了記錄。從日誌中可以看到,該字段爲空。Rails Activerecord更新保存未編輯的字段爲空

@anonymousxxx - 快速的回答,是的,如果它被編輯和空白。但事情就是這樣,編輯時這個字段並不是空白,或者不應該是空白。我在index.html.erb屏蔽了用戶的密碼(我沒有呈現swiftinfo.password值,只是顯示「*****」。爲了測試,我顯示了密碼值(swiftinfo.password)< %= swiftinfo.password%>並且確實存在密碼,所以當我編輯該記錄(或記錄)時,密碼又有一個值,因此,如果我不編輯該字段,而是編輯另一個字段或無場,更新應該保存當前值,編輯或原來,表
更新:
好吧,我已經分離出的問題是:
<%= f.password_field :password %> - Browser displays blank, record is saved with a blank value
%= f.text_field :password %>
顯示密碼明文,但記錄將正確的值(當前或更改)保存到表中。
如果密碼字段爲空,你不會更新密碼字段嗎? –
