Job delay giving an undefined method error

Question

The deferred task (2.1.4) works fine on my development machine, sending emails with gay rejection - however, when it starts on my server with Apache / Passenger (3.0.7) it fails. Rails 3.0.7 and ruby ​​1.9.2 on both devices.

I saw that there is a problem when using thin, where the task is created as follows:

--- !ruby/struct:Delayed::PerformableMailer object: !ruby/object:Class UserMailer 

when he should read:

 --- !ruby/struct:Delayed::PerformableMailer object: !ruby/class UserMailer 

Mines are created correctly on my development machine, but not when they are created on the server.

Has anyone else had this problem, where do I start looking?

Answer 1

I managed to fix it.

I created setup_load_paths.rb a few weeks ago when the provider somehow stopped working. This meant that the gemfile loaded everywhere except for the passenger. This confused the call to YAML :: ENGINE.yamler = "syck", which seems to have started saving the object.

I removed setup_load_paths and now everything works beautifully.

Answer 2

If using the Syck parser doesn't work (as mentioned in Marc's answer), try using a parser instead.

 YAML::ENGINE.yamler = "psych"
