我想在heroku上使用delayed_job,我收到以下错误：
Cannot enqueue items which do not respond to perform
我正在使用插件http://github.com/pedro/delayed_job
我正在使用以下cron rake任务(cron.rake)：
task :cron => :environment do
require 'heroku'
puts "starting the cron job at #{Date.today}"
heroku = Heroku::Client.new(ENV['HEROKU_USER'],ENV['HEROKU_PASS'])
heroku.set_workers(ENV['HEROKU_APP'],1)
Contact.all.each do |contact|
email = contact.email_today #email_today is a contact method returning email object if <= today
unless contact.email_today == "none"
puts contact.first_name
puts email.days
puts contact.date_entered
puts email.substituted_subject(contact,contact.colleagues)
# create the Contact Email object that gets created and sent
contact_email = ContactEmail.new
contact_email.contact_id = contact.id
contact_email.email_id = email.id
contact_email.subject = email.substituted_subject(contact,contact.colleagues)
contact_email.date_sent = Date.today
contact_email.date_created = Date.today
contact_email.body = email.substituted_message(contact,contact.colleagues)
contact_email.status = "sent"
Delayed::Job.enqueue OutboundMailer.deliver_campaign_email(contact,contact_email)
contact_email.save #now save the record
puts "save contact_email:"
puts contact_email.inspect
end #end unless
end #end do
heroku.set_workers(ENV['HEROKU_APP'],0)
puts "set heroku workers to 0"
end
这是我正在使用的邮件：
class OutboundMailer < Postage::Mailer
def campaign_email(contact,email)
subject email.subject
recipients contact.email
from 'Me <me@me.com>'
sent_on Date.today
body :email => email
end
解决方法
一个作业通常是一个带有“执行”方法的ruby对象,因此将邮件发送无效,您将不得不创建如下所示的作业对象,
class SomeMailJob < Struct.new(:contact,:contact_email)
def perform
OutboundMailer.deliver_campaign_email(contact,contact_email)
end
end
创建一个文件some_mail_job.rb并将其放在/ lib中
和
在上面的代码中,用en替换enqueue语句
Delayed::Job.enqueue SomeMailJob.new(contact,contact_email)
