# This initializer adds a method, show_mongo, when running a rails console. When active, all
# moped commands (moped is mongoid's mongodb driver) will be logged inline in the console output.
# If called again, logging will be restored to normal (written to log files, not shown inline).
# Usage:
#     > show_mongo

if defined?(Rails::Console)
    def show_mongo
        if Moped.logger == Rails.logger
            Moped.logger = Logger.new($stdout)
            true
        else
            Moped.logger = Rails.logger
            false
        end
