如何在 Rails 模型中获取当前用户 [英] How to get current user in Rails model

问题描述

我的应用程序使用 Rails 5.2，使用 sidekiq 处理后台作业.

I am using Rails 5.2 for my application and sidekiq for processing the background job.

class Document < ApplicationRecord
  has_many :document_jobs
end


class DocumentJob < ApplicationRecord

  belongs_to :document

  def self.create_document_job(document, status, details)
    document.document_jobs.create(status: status, details: details, user_id: user_id)
  end

  def self.update_document_job(document_job, status, details)
    document_job.update(status: status, details: details)
  end

end

我想将文档作业模型中的当前用户存储在数据库中.

I want to get the current user in Document job model to store in db.

我在所有 Sidekiq 工人中调用 create_document_job 方法

I am calling create_document_job method in all Sidekiq workers

class DocumentWorker
  include Sidekiq::Worker
  def perform(*args)
    document = Document.find_by_name("sample")
    document_job = DocumentJob.create_document_job(document, "processing", "job details")

  rescue StandardError => e
   DocumentJob.create_document_job(document_job, "failed", "job error details")
  end
end 

我想在 DocumentJob 模型的 create_document_job 方法中创建文档作业时获取当前用户 ID.我如何获取和存储它?

I want to get the current user id when creating the document job in create_document_job method of DocumentJob Model. How can I get it and store it?

推荐答案

您无法在作业中从 Devise 访问 current_user.因此，将其作为参数从您调用作业的位置发送.此外，Sidekiq 使用 Redis，它只保存键值对.所以不要传递用户对象而是用户 ID，然后在工作中你可以做 @user = User.find(user_id)

You can't access the current_user from Devise in the jobs. So send it as a param from where you call the job. Also, Sidekiq is using Redis, which only holds key-value pairs. So don't pass along the user object but the user ID and then in the job you can do @user = User.find(user_id)
