Question

我正在尝试将一个站点部署到engineyard上，并且我一直收到一个似乎是数据格式错误的错误。这仅在作为生产部署到服务器群集时发生。在本地或在VPS上使用相同的DB和代码库我们没有问题。在我看来，错误表明突然存在一些数据/散列类型与某些用户数据不匹配。它似乎总是追溯到模型，它的任务是获得“选项”。这些错误由要求访问用户属性检查的模板触发。

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

选项值的示例： --- !map:ActiveSupport::HashWithIndifferentAccess is_agent: "1"

Answer 1

发现该问题是数据库文件中的额外换行符。具体而言，该应用程序使用相当数量的序列化yaml数据。在yaml散列键和值之间添加了一个额外的换行符，导致对象内部出现错误。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。

Answer 2

这是我的案例错误

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

原因：

在我的haml中。

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active record where子句的实体数组）。我刚刚过滤了第一个元素。

希望有人会觉得有用。

仅生产错误ActionView :: Template ::错误（无法将符号转换为整数）
