延迟的作业"事件'成功'无法从

Question

我已经集成了延迟作业以从后台运行 Jenkins 构建。因此，对于每个构建，我都使用 gem 来更新我的状态AASM。每次构建完成后，我都会从延迟的工作中收到错误"Event 'success' cannot transition from 'success'因为为什么会发生，我无法找到。

我从我的approver_controller.rb打电话给我的工作

@build_request.delay(attempts: 1).run_batch

build_request模型中，我有我的作业方法来执行 Jenkins 批处理

class BuildRequest < ApplicationRecord
    include AASM
     aasm :column => :build_state do
        state :pending, initial: true
        state :onhold
        state :release
        state :approved
        state :rejected
        state :success
        state :failed
        event :approve do
            transitions from: [:pending], to: :approved
        end
        event :onhold do
            transitions from: [:pending], to: :onhold
        end
        event :release do
            transitions from: [:onhold], to: :pending
        end
        event :reject do
            transitions from: [:pending], to: :rejected
        end
        event :success do
            transitions from: [:approved], to: :success
        end
        event :fail do
            transitions from: [:approved], to: :failed
        end
    end
    def run_batch
            if self.approved?   
                file_name = "#{self.project_job_name}_#{self.id}.txt"
                new_file = File.open(file_name, "w+")
                new_file.puts self.project.job_name + "r"
                new_file.puts input_path(self)
                new_file.close
                FileUtils.mv(Rails.root.join(file_name), Rails.root.join('public'))
                Net::SCP.start(ENV["IP_ADDRESSS"], ENV["USER_NAME"], :password => ENV["PASSWORD"]) do |scp|
                # asynchronous upload; call returns immediately and requires SSH
                # event loop to run
                    channel = scp.upload(Rails.root.join('public', file_name).to_s, jenkins_build_path)
                    channel.wait
                end
                Net::SSH.start(ENV["IP_ADDRESSS"], ENV["USER_NAME"], :password => ENV["PASSWORD"]) do |ssh|
                    output = ssh.exec!("file_path" " file_name")
                    # start building job 
                    build_status = ApplicationController.helpers.jenkins_client.job.build(self.project_job_name)
                    build_status == "201" ? self.success : self.failed
                end
            end
        end

我遇到了同样的问题，我花了一些时间才弄清楚：

DelayedJob 会自动向模型添加success方法，并在作业完成后运行该方法。这可能会与您使用 AASM 执行的状态管理冲突，导致它(例如(处于成功状态(通过您的代码(，然后让延迟作业无意中尝试再次将其转换为成功状态。
