rails delayed_pa​​perclip process_in_background无效

Question

我有一个有图片的附件模型（定义的其余部分存在，但下面的行足够了）

has_mongoid_attached_file :picture

我想通过使用名为“process_in_background”的方法的“delayed_pa​​perclip”gem来调整大小调整过程：

process_in_background :picture

然后我开始了一个前台日志记录工作者：

./script/delayed_job run
delayed_job: process with pid 32393 started.

然后将文件发布到特定网址以上传文件并查看结果，但没有发生任何特殊情况。与工作人员一起上传的文件。 甚至我停止了工作人员并重新发布文件然后执行：

rake jobs:workoff

但没有任何人在排队！

即使我在puts "hello world"（在gem源代码中）的process_in_background方法的开头放了delayed_paperclip.rb，但没有记录任何意味着它没有被执行。

我该如何解决这个问题？ TNX。

Answer 1

即使paperclip支持mongoid，delayed_pa​​perclip也不支持。 我做了一个delayed_pa​​perclip的小分支来支持mongoid。它没有单元测试，因此可能是错误的，但它确实为我做了工作。 只需将include DelayedPaperclip::MongoidGlue行添加到您的模型中即可。
