Custom Logger to store logs based on class name or table name. A logger for each file. Create an initializer as cutom_logger.rb.

custom_logger.rb

# This should be an initializer.

# call this method anywhere in your app like this : 

CustomLogger.log "This message should go in the tab_development_errors.log" , :error , "Tab"

# a more better way is to do this : 

CustomLogger.log "This message should go in the tab_development_errors.log" , :error , tab_record.class.name.to_s (i know the .to_s is not necessary)
