uninitialized constant AuthTrail::ApplicationJob

[Wai Yan Yoon]

I have this error while running the install command rails generate authtrail:install. Is there anything I'm missing out(such as autoloading)? This project is using Ruby 2.4.2, Rails 5.0.2.

Nevermind, just found the issue of missing ApplicationJob because this Rails app is upgraded from older versions of Rails.

[ck2000]

I am getting the described error with rails 5.2.2.1. How can I solve this?

[Andrew Kane]

@ck2000 You need to add the file app/jobs/application_job.rb with:

class ApplicationJob < ActiveJob::Base
end

In future version, I'll likely have the AuthTrail job inherit from ActiveJob::Base directly to avoid this.
