我正在尝试将90k行xml导入我的ruby应用程序。 herokus超时限制为30秒，所以我试图使用延迟工作。
导入课在当地大约48个河马中运作良好。当我添加行
handle_asynchronously :save_races
我收到错误“未定义的方法save_races' for class Xmltube”“
我在DJ身上做错了什么？如何才能让它发挥作用？
以下全类代码
require "rexml/document"

答案 0 :(得分：1)
由于您的save_races是一种类方法，因此您应该在handle_asynchronously的单例类上调用Xmltube：
class << self
handle_asynchronously :save_races
end

这就像我期望的那样工作
class Foo
def self.bar(s)
Rails.logger.info "From Foo.bar('#{s}')"
end
end
# then ...
Foo.delay.bar('hello')
