我正在尝试将站点部署到engineyard，但我不断收到一个似乎是数据格式错误的错误。这只发生在作为生产部署到服务器集群上时。在本地或 VPS 上使用相同的数据库和代码库，我们没有问题。在我看来，这些错误表明突然有一个数组/哈希类型与某些用户数据不匹配。它似乎总是可以追溯到负责获取“选项”的模型。这些错误是由调用用户属性检查访问的模板触发的。

来自 user.rb 的代码似乎是错误的联系点：

def has_option?(option)
 self.options[option] && self.options[option].to_s == "1"
end

一个选项值的例子： --- !map:ActiveSupport::HashWithIndifferentAccess is_agent: "1"

来发现问题是数据库文件中的一个额外的换行符。具体来说，应用程序大量使用序列化的 yaml 数据。在 yaml 哈希键和值之间添加了一个额外的换行符，导致对象内出现错误。我们最初尝试创建一个脚本来清理数据库，然后发现它似乎只是从原始数据库文件中损坏了。

这是我的案子出了什么问题

Error : ActionView::Template::Error (can't convert Symbol into Integer)

原因：

在我的哈姆尔。

我试图从 json 对象访问属性。

object[:key]

但实际上它是一个 json 数组（来自活动记录 where 子句的实体数组）。我刚刚过滤了第一个元素。

希望有人会发现有用。
