Lock! Empty Resource Key Behavior (question)

[rypback]

Hi there,

I have a method that may or may not need to lock based on a few conditions. I've tried moving all of that logic to a separate method which takes a few arguments. I can call that method directly with no problem, however, I'm unable to turn that method into a block to call lock! since the method takes args. If that's possible, I'd love to hear how.

But I was curious about the resource key. If that were to be conditionally set, either to a unique string or empty string/nil/etc. What would the behavior be? Would it lock on the unique string and not acquire a lock for the empty (which would be ideal). Or would there still be an acquired lock for ''.

Thanks for any insight you can provide.

Example:

class JobClass
  def perform
    if some_value == some_other_value
      return lock!('resource_key', ttl: 2000) do
        # How can I pass `run_job` with the args it needs to this block
      end
    end

    # This is the easy case (calling the run method directly)
    run_job(ActiveRecordInstance, '', 0)
  end

  def run_job(object, string, number)
    # critical code here
  end
end
