【英文标题】：Rails: EOF Error when creating/updating a record

【问题描述】：

我最近偶然发现我的 rails 应用程序存在问题。 我正在使用 ruby​​ 2.1.0 和 Rails 3.2.7（我知道），最近，当我创建/更新任何模型的任何记录时，我的应用程序中出现 EOFError - bad content body: 错误。一切似乎都在数据库级别工作，因为如果我重新加载，可以看到更改（如果我创建新记录，它会显示在列表视图中，如果我更新记录，则会反映更改）。

这里是rails服务器的踪迹：

有人遇到过这样的问题吗？

【问题讨论】：

它说：多部分的身体坏了。你使用稳定的 HTTP 客户端吗？

是的，我没有改变任何东西。我唯一做的就是更新 gem 版本。也许它正在造成麻烦？另外，我发现这个问题不会影响当前使用该应用程序的用户。那部分真的很困扰我。

我刚刚在 Firefox 中尝试过，一切正常。是浏览器相关的吗？

可能是插件损坏

我在更新我的 gems 之前恢复到提交，强制安装 gems。仍然收到错误。

【参考方案1】：

问题可以找到here：

在问题中有许多解决问题的建议。它对我有用的是这个：

module Rack
  module Multipart
    class << self
      alias_method :original_parse_multipart, :parse_multipart
      def parse_multipart(env)
        begin
          original_parse_multipart(env)
        rescue EOFError => e 
          nil
        end
      end
    end
  end
end

我不是很喜欢，因为它只是忽略了问题，并没有指出错误的根源。
