问题
i am using delayed_job 2.1.0.pre2, and in my lib i have a class which named MailingJob(mailing_job.rb),and it has one method named perform. In my controller , i put a new MailingJob object in my delayed_job queue as the doc said. but when i run the "rake jobs:work" command,it always told me that it can't find "MailingJob", is it necessary to require the mailing_job.rb file?if yes,where should i put this? thanks!
回答1:
mailing_job.rb must be in a place where Rails can find and auto-load it. Where do you have that file? Unless it's in app/models or something like that, it won't find it on its own.
I have my jobs in app/jobs but this works because I added that path to the Rails load paths in the environment.rb Rails::Initializer.run block:
config.load_paths << "#{Rails.root}/app/jobs"
