Method: ETL.logger_root

Defined in:
lib/etl/etl.rb

.logger_root ⇒ Object

First tries to get the cached @@logger_root Second, sets the global @@logger_root unless it is cached. Sets it to the best possible place to locate the logs: 1) where log will be from RAILS_ROOT/vendor/gems/etl 2) where log will be in a Rails model 3) where log will be in a Rails lib 4) in the local directory where ETL is being subclassed Third, uses the subclasses stored logger_root, ignoring all the rest if this is found.
