通过 heroku 播种 mongoDB 时出错
Error when seeding mongoDB thru heroku
你好，我有一个基于 heroku 构建的应用程序，但我似乎无法让 mlab 数据库工作。它似乎连接但是当我 运行 heroku 运行 rake db:setup 我得到一个错误并且看不到它是什么。
我升级到付费帐户，但这并没有解决问题。请帮我解决这个问题。这是我的 mongoid.yml 文件
# Tell Mongoid which environment this configuration is for.

我的错误非常长，我似乎看不到最上面的几行，但这是我能看到的最上面的几行。

顺便说一句，我是 运行ning mongoid 4.0.2 和 rails 2.2.1

它似乎正在创建数据库但无法为其设定种子。然而，当我去查看数据库时，他们什么都没有，这让我觉得也许它开始构建数据库，当种子失败时，它会破坏它所做的。
问题原来是我在开发中使用的数据库是 MongoDB 的旧版本。我升级到 MongoDB 5，稍作修改后一切正常。

它似乎正在创建数据库但无法为其设定种子。然而，当我去查看数据库时，他们什么都没有，这让我觉得也许它开始构建数据库，当种子失败时，它会破坏它所做的。
问题原来是我在开发中使用的数据库是 MongoDB 的旧版本。我升级到 MongoDB 5，稍作修改后一切正常。
