如何使用Jruby和Rails在Heroku上部署Neo4j应用

Question

尝试在heroku和heroku logs上neo4j with jruby应用程序部署neo4j with jruby显示以下内容：

Neo4j has been shutdown using storage_path: /app/db/neo4j-production

应用程序配置如下：

## config/application.rb 

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

有什么想法可能是错误的吗？

1.对于我的heroku应用程序，我正在使用这个heroku neo4j插件

2.这是我用于回购的样例neo4j rails app回购。

听起来您的路线是错误的。 您当然知道Heroku不提供持久存储吗？ 不过，OpenShift确实可以。

在Heroku上，我将使用托管的GrapheneDB产品。 然后，您可以使用neography或neo4j.rb （在服务器模式下）连接到neo4j db。
