The default options to use for state machines using this integration
Whether this integration is available for the current library. This is usually only true if the ORM that the integration is for is currently defined. Default is false.
# File lib/state_machine/integrations/base.rb, line 23 def available? false end
Extends the given object with any version overrides that are currently active
# File lib/state_machine/integrations/base.rb, line 77 def extended(base) versions.each do |version| base.extend(version) if version.active? end end
The name of the integration
# File lib/state_machine/integrations/base.rb, line 10 def integration_name @integration_name ||= begin name = self.name.split('::').last name.gsub!(/([A-Z]+)([A-Z][a-z])/,'\1_\2') name.gsub!(/([a-z\d])([A-Z])/,'\1_\2') name.downcase! name.to_sym end end
The path to the locale file containing translations for this integration. This file will only exist for integrations that actually support i18n.
# File lib/state_machine/integrations/base.rb, line 70 def locale_path path = "#{File.dirname(__FILE__)}/#{integration_name}/locale.rb" path if File.exists?(path) end
Whether the integration should be used for the given class. Default is false.
# File lib/state_machine/integrations/base.rb, line 29 def matches?(klass) false end
Creates a new version override for an integration. When this integration is activated, each version that is marked as active will also extend the integration.
module StateMachine module Integrations module ORMLibrary version '0.2.x - 0.3.x' do def self.active? ::ORMLibrary::VERSION >= '0.2.0' && ::ORMLibrary::VERSION < '0.4.0' end def invalidate(object, attribute, message, values = []) # Override here... end end end end end
In the above example, a version override is defined for the ORMLibrary integration when the version is between 0.2.x and 0.3.x.
# File lib/state_machine/integrations/base.rb, line 62 def version(name, &block) versions << mod = Module.new(&block) mod end
Tracks the various version overrides for an integration
# File lib/state_machine/integrations/base.rb, line 34 def versions @versions ||= [] end
