[Rails] Upgrading to rails 5.0

Ruby on Rails Tuesday, July 25, 2017

Hi there,

I'm upgrading an app from rails 4.2.7 to 5.0.4.

I have updated the binary files through this command $rails app:update, and so far so good.

However, when i run this command $rails db:migrate, I get the following error:

rails aborted!

NoMethodError: undefined method `scheduler'

and the code it points is to this block: (the red is what is causing the error.

if !defined?(Rails::Console) && \

File.basename($0) != 'rake' && \

Rails.configuration.scheduler

scheduler_pid_file = File.join(Rails.root, "tmp", "scheduler.pid").to_s

Scheduler::start_unless_running scheduler_pid_file

end

I'm using gem 'rufus-scheduler', '~> 3.4.2'

Do you have any idea how to solve this?

Thank you for your time,

João Bordalo
