Rieles: Absolutamente perplejo con el trabajo retrasado. No recibo argumentos en ningún lado

Question

Estoy tratando de enviar correo en una aplicación de Rails 3 usando el trabajo retrasado de collectiveidea. Si trato de enviar correos regularmente (.deliver) funciona bien, pero tan pronto como cambio al trabajo retrasado, las cosas se desmoronan.

El error estándar de recibo en la tabla delayed_job MySQL es:

{método no definido `nombre' para nula: NilClass ...

donde 'nombre' es el primer argumento en la vista de correo (@ contact.name). Esto funciona bien si retiro el trabajo retrasado.

Si quito todas las referencias a @contact en la vista, consigo

{Un remitente (Return-Path, remitente o De) requerido para enviar un mensaje

En pocas palabras , no parece entender ningún argumento en absoluto.

Todo el código correspondiente a continuación - si alguien tiene alguna sugerencia para este sería muy apreciada

CONTROLADOR

def sendmail 
    @contact = Contact.new(params[:contact]) 
    if @contact.save 
     ContactMailer.delay.contact_mail(@contact) 
     flash[:notice] = 'Your message has been successfully sent' 
     redirect_to root_path 
    else 
     render :action => 'index' 
    end 
    end 

Mailer:

class ContactMailer < ActionMailer::Base 
    default :from => "my@email.address" 

    def contact_mail(contact) 
    @contact = contact 
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain') 
    end 
    handle_asynchronously :contact_mail, :run_at => Proc.new { 2.seconds.from_now } 
end 

Mailer VEA:

Answer 1

el problema es con el código en su programa de correo de tomar el objeto en lugar de los objetos Identificación:

def contact_mail(contact) 
    @contact = contact 
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain') 
end 

Usted debe cambiar para que esto:

def contact_mail(contact_id) 
    @contact = Contact.find(contact_id) 
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain') 
end 

Nunca pasan los objetos reales a su remitente. Simplemente pase los id y recupérelos al procesarlos.

Answer 2

¿Por qué no funciona? No estoy seguro, me imagino que tiene que ver con algún vudú de ActionMailer.

¿Cómo funciona? Resuma las piezas de trabajo retrasadas en otra clase. Haga que el método que se demora no haga más que enviarles un correo electrónico; lo que significa que la presentación del correo electrónico se realiza en tiempo real, pero el envío se retrasa. Esto debería evitar su problema y lograr el envío asincrónico de correos electrónicos.

Answer 3

Oye, esto podría estar lejos, pero no está enviando ningún parámetro a su CORREO. Aquí hay una copia de mi referid_email.rb Guardo en mi lib/dir. Lo llamo con delayed_job:

#my controller 
Delayed::Job.enqueue ReferredEmail.new(params[:subject], params[:editor1]) 

#Reffered_Email.rb 

class ReferredEmail < Struct.new(:subject, :editor1) 
    def perform 
    (CardReferral.all.map(&:email) - CardSignup.all.map(&:email)).each do |cf| 
     @cf = CardReferral.find_by_email(cf) 
     Notifier.deliver_referred_magic_email(User.find(@cf.user_id), @cf.email, @cf.name, @cf.message, subject, editor1) 
    end 
    end 
end 

Answer 4

Parece que están utilizando tanto:

ContactMailer.delay.contact_mail(@contact) 

y

handle_asynchronously :contact_mail, :run_at => Proc.new { 2.seconds.from_now } 

que sólo se debe hacer una o la otra. Intente quitar el handle_asynchronously y vea si eso soluciona el problema.

Answer 5

Tuve el mismo problema y lo solucioné moviendo todos los atributos a variables de instancia. Así, en la vista:

<%= @contact.name %> 
<%= @contact.business %> 
<%= @contact.phone %> 

se convierte en:

<%= @name %> 
<%= @business %> 
<%= @phone %> 

y Acabo de mirar las variables de instancia en el método de anuncio publicitario. Así, en el programa de correo:

def contact_mail(contact) 
    @contact = contact 
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain') 
end 

se convierte en:

def contact_mail(contact) 
    @name = contact.name 
    @business = contact.business 
    @phone = contact.phone 
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain') 
end
