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

标签: ruby-on-rails engineyard

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"

2 个答案:

答案 0 :(得分: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。

答案 1 :(得分:0)

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。
