我在将新添加的列中的信息写入我的mysql数据库时遇到问题。特别是＆＃39; site_email＆＃39;。当我在本地运行项目时，我可以使用我的新列内容写入数据库，它将显示在随后的显示页面上。
然而在开发服务器上我不能。开发服务器日志显示请求中发送的内容。
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"=>"test@email.comhello", "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
但是当它进入显示页面时，新的/更新电子邮件数据不存在。奇怪的是，如果我将任何数据添加到预先存在的列以及其他数据已成功发送到数据库但电子邮件不是。
索引显示和编辑页面都显示没有错误，如果我手动更改数据库中的信息，它将显示在显示页面上。因为发送请求数据并且页面没有产生错误，我甚至完全无法调试它。
来自/ var / www / sitename / current我跑bundle exec rake db:migrate
使用SequelPro连接到dev数据库我可以看到该列看起来就在那里，的确如果我在site_email列中插入一个数据，数据就会显示在显示页面上。

更新
在不更改内容的情况下，值会立即写入数据库。 24个左右。我现在遇到与实时服务器相同的问题。我正在等待另外24小时，看看是否对问题进行了分类，或者我是否意外地以其他方式修复了问题。
以防其他人将来有这个问题，有没有人知道为什么它会以这种方式行事？
更新2
实时服务器现在也更新了值。似乎服务器可能处于高负载或数据库以某种方式播放。
参考
如果您尝试在评论中尝试所有建议并参考Thomas＆＃39;回答这个应该在99.9％的情况下解决问题。如果它在本地工作但不在服务器上，并且您已经尝试了所有这些步骤，那么它可能与我所遇到的问题相同，不幸的是我目前还没有真正的答案。
答案 0 :(得分：2)
这可能是某种质量分配问题，如果除非已经进行了某些设置，否则属性会被静默删除。
尝试在您的网站模型中对:site_email的通话中添加attr_accessible。
# app/models/site.rb
...
attr_accessible :name, :site_email # mass-assignment protection
您需要列出您希望能够通过控制器中的@site.update_attributes(params[:site]更新的所有属性，并使用Site.new(name: ..., site_email: ...)或所谓的质量分配进行实例化，或者Site.create(name: ..., site_email: ...)。
