我目前想测试一下heroku mongoid mongolab / mongohq.

但是,我不想使用heroku插件,相反,我想配置mongoid通过uri oder其他设置直接使用mongolab / mongohq数据库.但是,这并没有真正奏效.

继承了迄今为止我所做的一切：

rails new test-mongoid --skip-active-record

的Gemfile

gem 'mongoid'
gem 'haml'
gem 'sass'

rails g mongoid:config

搭建一个测试模型

rails g scaffold Article title:string body:string

mongoid.yml

production:
  host: <%= ENV['MONGOID_HOST'] %>
  port: <%= ENV['MONGOID_PORT'] %>
  username: <%= ENV['MONGOID_USERNAME'] %>
  password: <%= ENV['MONGOID_PASSWORD'] %>
  database: <%= ENV['MONGOID_DATABASE'] %>

其他尝试已经使用mongoid.yml

production:
  uri: mongodb://<user>:<password>@<host>:<port>/<database>

填写我的用户名密码等

用mongodb在当地进行测试,一切正常.把它推到heroku,不起作用.

任何人都已经这样绕过那些heroku插件并知道如何处理它？

编辑

像这样配置我的mongoid.yml

production:
  sessions:
    default:
      hosts:
        - <server>:<port>
      username: <username>
      password: <password>
      database: <dbname>

似乎正在运行…但如果我试图去支架文章索引
app.herokuapp.com/articles

我明白了

解决方法

加

ruby '1.9.3'

到你的Gemfile.从Mongoid 3 + Heroku (MongoHQ) cause Moped::Errors::OperationFailure起

如果你在本地使用Ruby 1.9.3,你可能会认为这只是工作,但没有.
