ruby-on-rails - 尝试发送电子邮件时出现 sidekiq_mailer 错误

Question

我在我的应用程序中添加了 gem sidekiq (2.15.0) 和 sidekiq_mailer (0.0.6)。当我尝试发送电子邮件时，我收到:

NoMethodError (undefined method `key?' for #<JSON::Ext::Generator::State:0x007f1b......

有人知道为什么会这样吗？

根据 this comment on a resque issue我能够解决一个类似的问题，我试图将整个对象传递给工作人员的 perform 操作，而不仅仅是对象 ID。我重构了我的代码以仅传递一个 id 并在 worker 中获取必要的对象。

更深层次的问题是 sidekiq 只支持原生 JSON 类型，因此在尝试将对象传递给 sidekiq 时，它会抛出任何更复杂的东西，比如 ruby​​ 对象。参见 this thread有关更多详细信息和文档:

The arguments you pass to perform_async must be composed of simple JSON datatypes: string, integer, float, boolean, null, array and hash. The Sidekiq client API uses JSON.dump to send the data to Redis. The Sidekiq server pulls that JSON data from Redis and uses JSON.load to convert the data back into Ruby types to pass to your perform method. Don't pass symbols or complex Ruby objects (like Date or Time!) as those will not survive the dump/load round trip correctly.
