Rails 4 Sidekiq Errore costante non ritilizzato

Question

Ho problemi con la mia applicazione, quando si tenta di inviare e-mail sullo sfondo ottenendo errori uninitialized constant AnswersController::LazyDoer, non ho il minimo indizio Perché non funziona, nessun suggerimento?

Il mio lavoratore è in app/workers/lazy_doer.rb

Ecco il mio controller:

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

.

Qui hai il mio lavoratore:

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

.

Modifica:

Ho fatto il mio lavoratore lazydoer pienamente operativo, ma ora ho problemi con l'invio di email tramite esso.Cosa è più importante, Mailer funziona perfettamente senza Sidekiq .Ecco l'errore all'interno Sidekiq:

.

E qui hai il mio mailer:

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

Ho la soluzione, il problema con l'errore SIDEKIQ è stato che dal momento che utilizza il database NOSQL che è Redis, Redis non riesce a capire correttamente i dati dei binari complessi, come ad esempio i modelli di ActiveCord, se stai cercando di inviare al tuo lavoratore, diciamo, tutto utente con ogni singolo attributo che ha - questo non funzionerà in Redis, i dati sono troppo complessi.La soluzione è semplice, guarda esattamente alla tua vista e-mail generata e Mailer.rb e vedi esattamente quali attributi hai bisogno, allora quando è necessario chiamare il tuo lavoratore, inviagli solo quegli attributi, non inviare numerosi modelli di ActiveRecord.

Qui hai un lavoratore fisso:

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

.

Regolatore fisso (più 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

.

Medio utente fisso:

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 e-mail fissa (con l'uso del linguaggio sottile del modello invece di 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.
