ActionMailer in rake task

[Sven Schott]

Hi guys

I'm trying to use ActionMailer to send notifications outside of my controllers from a rake task but I'm getting an error saying the method is undefined.

NoMethodError: undefined method `hour_record_expiry_notification' for Notifier:Class

The ActionMailer class looks like this:

class Notifier < ActionMailer::Base

  ADMIN_ADDRESS = "XXXXX@XXXXX"

  def hour_record_expiry_notification(recipient,hour_record)

    recipients recipient.email_address_with_name

    from       ADMIN_ADDRESS

    subject    "Freetime: WARNING - Hours expire in 10 days or less"

    body       :user => recipient, :hour_record => hour_record

    content_type "text/html"

  end

end

and the rake task looks like this:

namespace :freetime do

  desc "Find hours that will expire soon and notify the owners"

  task :notify_expiry => :environment do

    a = User.find(5);b = HourRecord.find(129)

    Notifier.hour_record_expiry_notification(a,b)

    Rails.logger.info "Sent users expiry notifications."

  end

end

Notifier.instance_methods shows the method but I'm thinking there's some tricker involved since it isn't an instance. :)

I've googled around but I can't find anyone having the same problem which leads me to believe I'm doing something stupid or nobody does mail notifications with rake (This is a one off that runs from a cron job). Any ideas? I normally would crack my head a bit more but it's 4:30 and if I go home without solving it, I'll have to use the old shotgun.

Hi Sven,

Try:

Notifier.deliver_hour_record_expiry_notification(a,b)

Cheers,

Keith

Which veresion of ActionMailer are you using? 2.x or 3.x?

If you're using 3.x, you need to call .deliver after the mailer method name:

Notifier.hour_record_expiry_notification(a, b).deliver

If you're using 2.x, it's slightly different:

Notifier.deliver_hour_record_expiry_notification(a, b)

I'm planning to write the rake task to query few details from the model and sending the notification using ActionMailer object

I'm getting below error when I invoke the action mailer class in my rake task,

rake aborted!

#<NoMethodError: You have a nil object when you didn't expect it!

You might have expected an instance of ActiveRecord::Base.

The error occurred while evaluating nil.[]>

C:/Rails application/TEST/lib/tasks/notifier.rak

My code:

notifier.rake file under lib/tasks

task :notify => :environment do 

   begin

   **************

Notifier.deliver_submitted_list_notification(email_settings[RAILS_ENV], records )

end

notifier.rb model/notifier.rb

class Notifier < ActionMailer::Base

def submitted_list_notification(settings,records)

**********

end

end

Any help would be appreciated!!

[Nigel Sheridan-Smith]

Are you declaring your notification method as an instance method or a class method? 

def instance_method(params)

  ...

end

notifier = Notifier.new

notifier.instance_method(params)

OR

def self.class_method(params)

  ...

end

Notifier.class_method(params)

Cheers,

Nigel

Hi,

Try running your rake task with --trace so you can find out which line
of your code is raising that error.
