Question

我正在尝试通过以下方式在我的规格范围内创建作业，但始终收到ArgumentError：-

MyJob.new.perform_now(user_id: @current_user.id, building_ids: [building.id])

module ActionPlan
class MyJob < ApplicationJob
queue_as :low

def perform(user_id:, building_ids:, **_args)
  @user = User.find(user_id)
  @buildings = ActionPlan::Reminder.where(user_id: user_id)
  @buildings.map(&method(:create_alerts))
end

我不断收到wrong number of arguments (given 1, expected 0) (ArgumentError)。我要去哪里错了？ perform方法带有2个参数，对吗？我该如何调试？

尝试一下：

module ActionPlan
  class MyJob < ApplicationJob
    queue_as :low

    def initialize(user_id:, building_ids:, **_args)
      @buildings = ActionPlan::Reminder.where(user_id: user_id)
    end

    def perform
      buildings.map(&method(:create_alerts))
    end

    private

    attr_accessor :buildings
  end
end

那应该可以让您打电话：

MyJob.new(user_id: @current_user.id, building_ids: [building.id]).perform

Rails ArgumentError on Job-错误的参数数量-如何调试？
