我正在使用SQS作为我的ActiveJobs的后端。Rails ActiveJob SQS和记录在执行作业时仍然不存在
我有被发送到队列中after_create回调我的模型的一个非常简单的工作：
after_create :update_stuff_after_create
这初始化一个ActiveJob：
UpdateStuffAfterCreateJob.perform_later(self.id)
将作业发送到SQS正确排队。问题是，其他实例谁是负责从队列中读取时试图执行的工作，我看到一个ActiveRecord::RecordNotFound：
class UpdateStuffAfterCreateJob < ActiveJob::Base
def perform(id)
publisher_offer_click = MyModel.find(id) # ActiveRecord::RecordNotFound
my_model.update_stuff
end
end
貌似在发作业，但该实例存在记录记录在使用作业的实例中不存在。
我一直在调试更深，我创建这个工作：
class TestingEntityExistsJob < ActiveJob::Base
def perform(id, exists_outside, time_outside_string)
Rails.logger.info "[TestingEntityExistsJob] #{id}, #{MyModel.last.id}, #{Time.now.strftime("%H:%M:%S.%L")}, #{time_outside_string}, exists: #{MyModel.where(:id => publisher_offer_click_id).exists?}, exists_outside: #{exists_outside}"
end
end
而且我在我的模型的after_create这样称呼它：
TestingEntityExistsJob.perform_later(self.id, MyModel.where(:id => self.id).exists?, Time.now.strftime('%H:%M:%S.%L'))
我有这样奇怪的结果：

您可以从外部看到记录始终为exists，但并不总是在作业执行内部。有时候MyModel.last.id比我尝试加载的记录的id小。
任何暗示为什么会发生这种情况的建议？我究竟做错了什么？
我实际的解决办法是'UpdateStuffAfterCreateJob.set（：等待=> 2.seconds）.perform_later（ self.id）'我认为丑陋，它不应该是必要的：/ – fguillen
