Mongoid 无效查找错误 rails

Question

我知道这个错误来自我的控制器中的 find 方法，但我不太确定如何修复错误。我正在尝试创建一个完整的方法，以便可以通过复选框将帖子存档并从索引页面中删除。目前的路由在相关的完整管理诊断中还没有 :id 所以我想知道这是否也是一个问题。我也在使用 rails 3.

错误

Mongoid::Errors::InvalidFind in Admin::DiagnosticsController#complete

    Problem:
  Calling Document.find with nil is invalid.
Summary:
  Document.find expects the parameters to be 1 or more ids, and will return a single document if 1 id is provided, otherwise an array of documents if multiple ids are provided.
Resolution:
  Most likely this is caused by passing parameters directly through to the find, and the parameter either is not present or the key from which it is accessed is incorrect.

Answer 1

请检查 params[:id] 不是 nil
