Logger is not initialised by default in a Rails 6 environment

[molfar]

I set up sneakers with rails project. Everything following instructions. But have this error:

Unexpected error undefined method `debug' for nil:NilClass
Did you mean?  debugger
  /Users/molfar/.rbenv/versions/2.5.3/lib/ruby/gems/2.5.0/gems/sneakers-2.11.0/lib/sneakers/worker.rb:114:in `worker_trace'

I think its because

sneakers/lib/sneakers/worker.rb

Line 123 in 24abf5f

logger.debug(log_msg(msg))

does not check if logger exists.
It will be better that sneakers use rails logger or stdout by default, with no config.

This project is not tied to Rails. We should make the logging method more defensive. You are welcome to contribute a PR.

I've managed to work around this problem (with Rails 6.0.0) by explicitly setting the logger.

Sneakers.logger = Rails.logger
Sneakers::Worker.logger = Rails.logger
