Module: Logging::Rails::Mixin

Defined in:

lib/logging/rails/mixin.rb

Overview

Include this module into your ApplicationController to provide per-controller log level configurability. You can also include this module into your models or anywhere else you would like to control the log level.

Alternatively, you can use the ‘include Logging.globally` trick to add a `logger` method to every Object in the ruby interpreter. See github.com/TwP/logging/blob/master/lib/logging.rb#L194 for more details.

Class Method Details

.extended(other) ⇒ Object

This method is called when the modules is extended into another class or module. It will remove any existing ‘logger` method and insert its own version.

# File 'lib/logging/rails/mixin.rb', line 25

def self.extended( other )
  eigenclass = class << other; self; end
  eigenclass.__send__(:remove_method, LOGGER_METHOD.to_sym) if eigenclass.instance_methods.include? LOGGER_METHOD
end

.included(other) ⇒ Object

This method is called when the module is included into a class. It will extend the including class so it also has a class-level ‘logger` method.

# File 'lib/logging/rails/mixin.rb', line 17

def self.included( other )
  other.__send__(:remove_method, LOGGER_METHOD.to_sym) if other.instance_methods.include? LOGGER_METHOD
  other.extend self
end

Instance Method Details

#logger ⇒ Object

Returns the logger instance.

# File 'lib/logging/rails/mixin.rb', line 31

def logger
  @logger ||= ::Logging::Logger[self]
end
