Neo4j с рельсами проекта Jruby

Question

Я пытаюсь использовать neo4j с Ruby on rails на Mac OSX. Я установил jruby и neo4j с варевом. я после этого руководства: http://wiki.neo4j.org/content/Getting_Started_With_Ruby и это: https://github.com/andreasronge/neo4j Во-первых, мой сервер Neo4j начал, и я был в состоянии создать узел и отношения.

Я создал новый gemset с RVM (ree install jruby @ neo4j). Во-вторых, первое руководство было успешным.

Итак, я создал новый проект с вторым руководством команды. Проект был создан, и пакет был успешным. Но когда я пошел, чтобы запустить сервер (rails s) он дал мне:

NameError: uninitialized constant Neo4j::Rails::Application 
    const_missing at org/jruby/RubyModule.java:2590 
      Neo4j at /Users/guillaumelegendre/dev/boosket/neo4j/config/application.rb:19 
     (root) at /Users/guillaumelegendre/dev/boosket/neo4j/config/application.rb:18 
     require at org/jruby/RubyKernel.java:1038 
     (root) at /Users/guillaumelegendre/dev/boosket/neo4j/config/application.rb:52 
      tap at org/jruby/RubyKernel.java:1804 
     (root) at /Users/guillaumelegendre/.rvm/gems/jruby-1.6.3@neo4j/gems/railties-3.1.3/lib/rails/commands.rb:49 
     require at org/jruby/RubyKernel.java:1038 
     (root) at script/rails:6 

Я искал в Google, но я did't найти кого-нибудь с той же ошибкой.

И это был мой application.rb, но это application.rb принадлежность к руководству второго сценария:

require File.expand_path('../boot', __FILE__) 

require 'action_controller/railtie' 
require 'action_mailer/railtie' 
require 'active_resource/railtie' 
require 'rails/test_unit/railtie' 
require 'will_paginate/railtie' 
require 'neo4j' 


if defined?(Bundler) 
    # If you precompile assets before deploying to production, use this line 
    Bundler.require(*Rails.groups(:assets => %w(development test))) 
    # If you want your assets lazily compiled in production, use this line 
    # Bundler.require(:default, :assets, Rails.env) 
end 

module Neo4j 
    class Application < Rails::Application 
    # Settings in config/environments/* take precedence over those specified here. 
    # Application configuration should go into files in config/initializers 
    # -- all .rb files in that directory are automatically loaded. 

    # Custom directories with classes and modules you want to be autoloadable. 
    # config.autoload_paths += %W(#{config.root}/extras) 

    # Only load the plugins named here, in the order given (default is alphabetical). 
    # :all can be used as a placeholder for all plugins not explicitly named. 
    # config.plugins = [ :exception_notification, :ssl_requirement, :all ] 

    # Activate observers that should always be running. 
    # config.active_record.observers = :cacher, :garbage_collector, :forum_observer 

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. 
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC. 
    # config.time_zone = 'Central Time (US & Canada)' 

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded. 
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s] 
    # config.i18n.default_locale = :de 

    # Configure the default encoding used in templates for Ruby 1.9. 
    config.encoding = "utf-8" 

    # Configure sensitive parameters which will be filtered from the log file. 
    config.filter_parameters += [:password] 

    # Enable Neo4j generators, e.g: rails generate model Admin --parent User 
    config.generators do |g| 
     g.orm    :neo4j 
     g.test_framework :rspec, :fixture => false 
    end 

    # Configure where the neo4j database should exist 
    config.neo4j.storage_path = "#{config.root}/db/neo4j-#{Rails.env}" 


    # Enable the asset pipeline 
    config.assets.enabled = true 

    # Version of your assets, change this if you want to expire all your assets 
    config.assets.version = '1.0' 
    end 
end 

Answer 1

Странно, какая версия рельсов, JRuby и Neo4j вы используете? Он должен работать из коробки:

gem install rails 
rails new myapp -m http://andreasronge.github.com/rails3.rb 
cd myapp 
bundle 
rails generate scaffold User name:string email:string 
rails s 
open a webbrowser: http://localhost:3000/users 

Как я могу воспроизвести эту проблему?
