DataMapper backend for delayed_job

delayed_job DataMapper backend

Installation

Add the gems to your Gemfile:

gem 'delayed_job', '2.1.0.pre2'
gem 'delayed_job_data_mapper', '1.0.0.rc'

If you're using dm-rails gem, add this to your environment.rb:

XXX::Application::configure do
 config.after_initialize do
   Delayed::Worker.backend.auto_upgrade!
 end
end

Otherwise, add an initializer:

Delayed::Worker.backend.auto_upgrade!

That's it. Use delayed_job as normal.

delayed_job_data_mapper's Issues

Latest Delayed Job

It appears that there is a much newer delayed job (3.0+) but it appears that the gem version of delayed_job_data_mapper is still 1.0.0.rc and is linked to 2.1.4.

I'd like to update this all if I can, but wanted to create this issue to start the discussion.

Gem release

Can we get a gem release to replace 1.0.0.rc? I think master is working with dj on master. May need a gem release their too.

Can't perform rake jobs:work

Getting an error:

$ rake jobs:work
syck has been removed, psych is used instead

I do:

  def perform
    store(dump)
    cleanup
  end
  handle_asynchronously :perform

A job is stored but can't be executed.

I'm using Sinatra, Ruby 2.0.0, the egde version of delayed_job_data_mapper and 1.2.0 version of datamapper

datamapper 1.1.0

Please upgrade the Gemfile to make it work with datamapper 1.1.0.

Did this ever work?

According to this: http://datamapper.lighthouseapp.com/projects/20609/tickets/1019-built-in-to_yaml-method-gives-anonymous-class-error

DataMapper intentionally returns Hash objects when you YAML.load a #to_yaml DataMapper instance. If that is the case then without explicitly overwriting this method in each class how could the DataMapper backend ever work?

auto_upgrade! method missing

I'm trying to configure this to work with MongoMapper but I'm having problems with the initializer:

/home/abel/.rvm/gems/ruby-1.8.7-p299/gems/dm-core-1.0.2/lib/dm-core/model/relationship.rb:373:in method_missing': undefined methodauto_upgrade!' for Delayed::Backend::DataMapper::Job:Class (NoMethodError)

I can't find that method anywhere in the code either.

Support for lasted activesupport versions

It would be nice to have support for lasted activesupport versions, otherwise this can screw some projects... :(

In snapshot (Gemfile.lock):
activesupport (= 4.2.1)

In Gemfile:
delayed_job_data_mapper (>= 0) ruby depends on
delayed_job (~> 4.0) ruby depends on
activesupport (< 5.0, >= 3.0)
ruby
activesupport (>= 0) ruby

delayed_job_data_mapper (>= 0) ruby depends on
dm-active_model (> 1.0) ruby depends on
activemodel (> 3.1.0) ruby depends on
