Geokit在Ruby on Rails的，與acts_as_mappable

Question

問題我已經通過相關的問題清單看着然而我的問題似乎並沒有上市，因此在這裏它是：

基本上我試圖內使用Geokit Ruby on Rails的環境中，即時通訊不知道我是否正確安裝了它，我的environment.rb文件中包含它（和做耙分貝：安裝），現在我正在努力做到以下幾點：

require 'active_record' 
require 'geokit' 

class Store < ActiveRecord::Base 
    acts_as_mappable 
end 

Unforunately ，當我嘗試運行這個，看看它的好，我得到以下錯誤：

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 

我在Visual Studio 2008中運行Ruby in Steel，我不確定我在做什麼錯誤，因爲我發現所有在線教程都傾向於比較陳舊並且適用於我。任何幫助將不勝感激。謝謝！

你用什麼樣的方式包括geokit圖書館

Answer 1

acts_as_mappable是geokit-rails的一部分。您需要安裝geokit-rails插件。

script/plugin install git://github.com/andre/geokit-rails.git 

要檢查插件是否安裝正確，請查看您的Rails應用程序的vendor/plugins目錄。它應該有一個geokit-rails子目錄。它，你會發現所有的插件文件，其他子目錄，包括文件acts_as_mappable.rb（在vendor\plugins\geokit-rails\lib\geokit-rails）。

如果一切似乎都已正確安裝，請嘗試將"require geokit"添加到插件根文件夾（vendor\plugins\geokit-rails）中init.rb文件的頂部。

確保在進行修改後重新啓動您的應用服務器。

？該插件？寶石？寶石是否解包到供應商？你的environment.rb是什麼樣的？
