Rails 4 Sidekiq Error constante no inicializado

Question

Tengo problemas con mi solicitud, al intentar enviar correos electrónicos en el fondo, obtengo un error uninitialized constant AnswersController::LazyDoer, no tengo menor pista ¿Por qué no funciona, alguna sugerencia?

Mi trabajador está en app/workers/lazy_doer.rb

Aquí está mi controlador:

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

Aquí tienes a mi trabajador:

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

Hice mi trabajador de LazyDoer en pleno funcionamiento, pero ahora tengo un problema con enviarle un correo electrónico a través de él.Lo que es más importante, mailer funciona perfectamente sin sidekiq .Aquí está el error dentro de Sidekiq:

y aquí tienes mi correo:

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

Tengo solución, el problema con el error Sidekiq fue que, dado que está utilizando la base de datos NOSQL, que está redis, Redis no puede comprender adecuadamente los datos complejos de los rieles, como por ejemplo los modelos ActiveCord, si está intentando enviar a su trabajador, digamos, el usuario completo con cada atributo que tiene, esto no funcionará en Redis, los datos son demasiado complejos.La solución es simple, vea exactamente a su vista de correo electrónico generada y su correo electrónico y vea exactamente qué atributos necesita, entonces, cuando debe llamar a su trabajador, envíe solo esos atributos, no envíe modelos enteros de actores.

Aquí tienes un trabajador fijo:

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

controlador fijo (lo más importante):

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

Correo de usuario fijo:

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

Vista de correo electrónico fija (con el uso de lenguaje de plantilla SLIM en lugar de 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

Instead of sending user object in @question_owner send user id.
