Rails code: Accessors.send :define_method, :"default_#{name}", &block
Accessors.module_eval <<-METHOD, __FILE__, __LINE__ + 1 def #{name} @details.fetch(:#{name}, []) end def #{name}=(value) value = value.present? ? Array(value) : default_#{name} _set_detail(:#{name}, value) if value != @details[:#{name}] end remove_possible_method :initialize_details def initialize_details(details) #{initialize.join("\n")} end METHOD end Here we invoke send() on the module Accessors, passing the :define_method symbol, which represents the define_method private method available from Class class. We create an instance method called default_locale, whose value is the block passed from register_detail class method of ActionView::LookupContext. Note that we later use "include Accessors" within LookupContext class to make that available as an instance method of LookupContext. We then create more instance methods using module_eval, with here-documents to specify our delimiter (METHOD) and the dynamic constants (__FILE__, __LINE__) for accurate error reporting on stacktrace. My question is why not include default_#{name} as part of the evaluated string in module_eval, rather than invoking send() directly above that using define_method? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
