Question

As you may know Logger:Application has constants (Logger::DEBUG, Logger::WARN etc…)

My log level is a string in my config. Passing that string to my logger gives error. I’ll have to override the level method to accept a string.

log = Logger.new($CONFIG.log.file, $CONFIG.log.freq)
log.level = $CONFIG.log.level ## << Error
#log.level = Logger::WARN ## < manually settings it as example in doc. 

how would you set the logging level dynamically?

Answer 1

Use const_get:

log_level = 'WARN'
log.level = Logger.const_get(log_level)  #=> 2  (which is the value of Logger::WARN)

Be careful with your input though, as Logger::Error & Logger::ERROR are not the same thing.
