Question

我的应用程序有问题，当我尝试在后台发送电子邮件时出现错误uninitialized constant AnswersController::LazyDoer，我没有丝毫线索为什么它不起作用，有什么建议吗？

我的工作人员在app/workers/lazy_doer.rb

这是我的控制器：

class AnswersController < ApplicationController
  before_action :authenticate_user!
  before_action :set_question, except: [:adding_likes,:accept]

  def create
    @answer = Answer.new(answer_params)
    @answer.user_id = current_user.id
    @answer.question_id = @question.id
    @question_owner = User.find(@question.user_id)

    if @answer.save
      LazyDoer.perform_async(@question_owner,current_user,@answer,@question)
      redirect_to question_path(@question), notice: "Answer was successfully created."
    else    
      render(:template => "questions/show", alert: "There was an error when adding answer.")

    end
  end

这里有你的工人：

class LazyDoer
  include Sidekiq::Worker
  sidekiq_options retry: false

  def perform(question_owner,current_user,answer,question)
    @question_owner = question_owner
    @current_user = current_user
    @answer = answer
    @question = question
    UserMailer.send_email(@question_owner,@current_user,@answer,@question).deliver
  end
end

编辑：

我让我的LazyDoer工作人员完全投入运营，但现在我遇到通过它发送电子邮件的问题。最重要的是， MAILER在没有SIDEKIQ的情况下完美运作。这是sidekiq里面的错误：

在这里你有我的邮件：

class UserMailer < ActionMailer::Base
  default from: "matthew.kilan@gmail.com"

  def send_email(question_owner,cur_user,answer,question)
    @question_owner = question_owner
    @cur_user = cur_user
    @answer = answer
    @question = question
    mail(to: @question_owner.email, subject: "Answer added to your question:")
  end

  def accepted_email(user,answer,question)
    @user = user
    @answer = answer
    @question = question
    mail(to: @user.email, subject: "Your answer has been accepted")
  end
end

Answer 1

我有解决方案，Sidekiq错误的问题是，因为它使用的是redis的nosql数据库，redis无法正确理解复杂的rails数据，例如ActiveRecord Models，如果你试图发送给你的工人让我们说，整个用户拥有他拥有的每一个属性 - 这在redis中不起作用，数据太复杂了。解决方案很简单，请仔细查看生成的电子邮件视图和mailer.rb，并确切了解您需要哪些属性，然后当您需要致电您的工作人员时，只发送给他那些属性，不要发送整个ActiveRecord模型。

这里有固定工人：

class LazyDoer
  include Sidekiq::Worker
  sidekiq_options retry: false

  def perform(question_owner_email,current_user_name,answer_contents,question_title)
    UserMailer.send_email(question_owner_email,current_user_name,answer_contents,question_title).deliver
  end
end

固定控制器（最重要的）：

class AnswersController < ApplicationController
  before_action :authenticate_user!
  before_action :set_question, except: [:adding_likes,:accept]

  def create
    @answer = Answer.new(answer_params)
    @answer.user_id = current_user.id
    @answer.question_id = @question.id
    @question_owner = User.find(@question.user_id)

    if @answer.save
      LazyDoer.perform_async(@question_owner.email,current_user.name,@answer.contents,@question.title)
      #DLA MAILERA BEZ SIDEKIQ UserMailer.send_email(@question_owner,current_user,@answer,@question).deliver
      redirect_to question_path(@question), notice: "Answer was successfully created."
    else    
      #redirect_to question_path(@question), alert: "There was an error when adding answer."
      render(:template => "questions/show", alert: "There was an error when adding answer.")
    end
  end
end

修正了用户邮件：

class UserMailer < ActionMailer::Base
  default from: "matthew.kilan@gmail.com"

  def send_email(question_owner_email,cur_user_name,answer_contents,question_title)
    @question_owner_email = question_owner_email
    @cur_user_name = cur_user_name
    @answer_contents = answer_contents
    @question_title = question_title
    mail(to: @question_owner_email, subject: "Answer added to your question:")
  end
end

修正了电子邮件视图（使用超薄模板语言而不是erb）：

doctype html
html
    head
        meta content="text/html; charset=UTF-8" http-equiv="Content-Type"
    body
        h1 Your question #{@question_title} has been answered
        p   
            |
                Answered by #{@cur_user_name}
                <br />
                The answer content is:
                <br />
                #{@answer_contents}

        p Accept or like the answer if it was useful for you.

Answer 2

而不是在@question_owner中发送用户对象发送用户ID。
