я просмотрел список связанных вопросов, однако моя проблема, похоже, не указана, и, следовательно, вот она:
В основном я пытаюсь использовать Geokit в среде Ruby on Rails, я не уверен, правильно ли я его установил, я включил его в environment.rb (и выполнил rake db: install), и теперь я пытаюсь сделать следующий:
require 'active_record'
require 'geokit'
class Store < ActiveRecord::Base
acts_as_mappable
end
К сожалению, когда я пытаюсь запустить это и посмотреть, все ли в порядке, я получаю следующую ошибку:
c:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/base.rb:1959:in `method_missing': undefined local variable or method `acts_as_mappable' for #<Class:0x4cd261c> (NameError)
from C:/Users/Erika/Documents/Visual Studio 2008/Projects/StoreLocator/StoreLocator/app/models/store.rb:5
Я запускаю Ruby in Steel для Visual Studio 2008, я не уверен, что делаю неправильно, так как все онлайн-руководства, которые я нахожу, имеют тенденцию быть довольно старыми и применимы ко мне. Любая помощь будет принята с благодарностью. Спасибо!
