Geokit在Ruby on Rails的，问题acts_as_mappable [英] Geokit in Ruby on Rails, problem with acts_as_mappable

问题描述

我已经通过了相关的问题清单看上去不过，看来我的问题并没有被列入到，因此这里是：

基本上我试图on Rails的环境中使用Geokit了Ruby中，即时通讯不知道我是否安装得当，我已经把它列入了environment.rb文件中（和完成耙分贝：安装），我现在想做到以下几点：

 要求'active_record
需要'geokit

一流的商店和LT;的ActiveRecord :: Base的
    acts_as_mappable
结束
 

Unforunately，当我尝试运行这一点，如果看到它的好了，我得到以下错误：

  C：/ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.4/lib/active_record/base.rb：1959年：在`method_missing的'：不确定的地方变量或方法`acts_as_mappable'的＃＆LT;类别：0x4cd261c＆GT; （NameError）
    从C：/用户/埃里卡/文档/ Visual Studio 2008中/项目/ StoreLocator / StoreLocator /应用/型号/ store.rb：5
 

我正在运行的Ruby钢为Visual Studio 2008，我不知道我在做什么错了，因为所有的在线教程，我觉得往往是相当老，做适用于我。任何帮助将大大AP preciated。谢谢！

解决方案

acts_as_mappable 是geokit护栏的一部分。您需要安装geokit-Rails插件。

 脚本/插件安装的git：//github.com/andre/geokit-rails.git
 

要检查插件是否正确安装，看看你的Rails应用程序的供应商/ plugins目录下。它应该有一个geokit护栏子目录。它，你会发现所有的插件文件，其他的子目录，包括文件 acts_as_mappable.rb （在厂商\插件\ geokit护栏\ LIB \ geokit护栏）。

如果一切似乎正确安装，尝试添加要求geokit在插件根文件夹中init.rb文件的顶部（供应商\插件\ geokit护栏）。

请务必使修改后重新启动你的应用服务器。

i have looked through the list of related questions however my problem does not seem to be listed and hence here it is:

Basically I'm trying to use Geokit within the Ruby on Rails environment, im not sure if i installed it properly, I have included it within the environment.rb (and done rake db:install) and i'm now trying to do the following:

require 'active_record'
require 'geokit'

class Store < ActiveRecord::Base
    acts_as_mappable
end

Unforunately, when i try to run this and see if its ok, i get the following error:

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

I am running Ruby in Steel for Visual Studio 2008, i'm not sure what i'm doing wrong as all the online tutorials i find tend to be rather old and done apply to me. Any help would be greatly appreciated. thanks!

Edit: (adding as per Ben's Request) The following is what my environment.rb looks like

解决方案

acts_as_mappable is part of geokit-rails. You need to install the geokit-rails plugin.

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

To check if the plugin is properly installed, look under the vendor/plugins directory of your Rails app. It should have a geokit-rails sub directory. It it, you'll find all the plugin files, other subdirectories, including the file acts_as_mappable.rb (in vendor\plugins\geokit-rails\lib\geokit-rails).

If everything seems to be properly installed, try adding "require geokit" to the top of the init.rb file in the plugin root folder (vendor\plugins\geokit-rails).

Be sure to restart your app server after making the modifications.
