my_zipcode_gem迁移发生器不工作

Question

我敢肯定，这个问题是由于这个gem看起来要3-4岁，并且rails改变了我们如何迁移的事实。但我对宝石/发电机不太熟悉。我试图按照说明执行here中列出的说明。

rails g my_zipcode_gem:models 
rake db:migrate 
rake zipcodes:update 

然而，当我这样做的第一步我最终得到这样的：

任何想法，我需要做的就是创业板的工作？它在我的应用程序中提供了我正在寻找的内容。

谢谢！

编辑：添加代码生成：

    class ModelsGenerator < Base 
    include Rails::Generators::Migration 

    source_root File.expand_path('../templates', __FILE__) 

    def initialize(*args, &block) 
     super 
    end 

    def generate_models 
     # puts ">>> generate_zipcodes:" 
    end 

    def add_gems 
     add_gem "mocha", :group => :test 
    end 

    def create_models

     template 'county_model.rb', "app/models/county.rb"

     end 
    end 

    def create_migration

    end 

    def create_rakefile

    end 
end

它看起来就像是调用使用不再需要的参数迁移。你有两个选择：

1）分叉代码，更新它使用rails 4约定，并在github上创建一个pull请求。假设所有者仍然处于活动状态，他们会将您的代码带入主服务器并重新发布该宝石。你将有助于支持社区，并在这个过程中感受良好。像我这样的人有很多可以帮助你的人。

2）找到另一颗宝石做你想要的东西，比如http://www.rubygeocoder.com/我已经多次使用，并在做位置/邮编问题
