Rails ActiveJob 从控制器启动

Question

我有一些自定义代码可以调用一些后端系统并远程更新数据库。我有一个执行任务的 ActiveJob：

## Runs join code
class DataJoin < ApplicationJob
  queue_as :default

  def perform
    join = Joiner.new
    join.run
    NotifMailer.sample_email.deliver_now
  end
end

我想从 controller/view:

手动启动 ActiveJob

class AdminController < ApplicationController
  before_action :verify_is_admin

  private def verify_is_admin
      (current_user.nil?) ? redirect_to(root_path) : (redirect_to(root_path) unless current_user.admin?)
  end

  def index
    @username = current_user.name
    @intro = "Welcome to the admin console"
  end

  def join
   ## Code to start ActiveJob DataJoin??
  end
end

如何从控制器启动 ActiveJob？

Answer 1

试试这个：

DataJoin.perform_later

perform_later 将作业排入指定队列。如果您的活动作业的 perform 方法接受一些参数，您甚至可以将它们传递给 perform_later，这些参数将在执行时可用。

DataJoin.perform_later(1, 2, 3)

# DataJoin
def perform(a1, a2, a3)
  # a1 will be 1
  # a2 will be 2
  # a3 will be 3
end

Answer 2

请阅读official guide on ActiveJob

def join
  DataJoin.perform_later
end
