Question

我有一个带有MongoID 3的Rails 3应用程序成功部署到Heroku（使用MongoHQ） - 但后来发生了一些事情（无法确切地指出它是什么）并且构建开始在Heroku上崩溃。

所以这是我得到的错误：

TLDR： Moped::Errors::AuthenticationFailure (The operation: #<Moped::Protocol::Commands::Authenticate ... failed with error "auth fails")

使调试更加困难的原因是它在localhost上运行得很好。现在我的想法已经不多了。

我最近一直在努力使用Heroku，因此我认为我应该选择正确的数据库选择db驱动程序＆amp; service（在Gemfile中使用新的yml方案+ Ruby 1.9.3）。

当我运行heroku config --app app_name时，我得到了

DATABASE_URL        => postgres://rhalppyjrb:xyz@ec2-xyz.compute-1.amazonaws.com/rhalppyjrb
GEM_PATH            => vendor/bundle/ruby/1.9.1
LANG                => en_US.UTF-8
MONGOHQ_URL         => mongodb://heroku:xyz@flame.mongohq.com:27054/app123
PATH                => bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin
RACK_ENV            => production
RAILS_ENV           => production
SHARED_DATABASE_URL => postgres://rhalppyjrb:xyz@ec2-123.compute-1.amazonaws.com/rhalppyjrb

我的mongoid.yml看起来像这样：

production:
  sessions:
    default:
          uri: <%= ENV['MONGOHQ_URL'] %>
          options:
            consistency: :strong
            skip_version_check: true
            safe: true

Gemfile是这样的：

source 'https://rubygems.org'

gem 'bundler', '1.2.0.rc'

ruby '1.9.3'

gem 'rails', '3.2.6'
gem 'thin'
gem 'rmagick', :require => 'RMagick'

问题是您的身份验证凭据不再正确。具体而言，您尝试进行身份验证的用户已不再存在。

原因是当您执行rake db:reseed时，所有数据都将被删除，包括数据库级用户。

示例：

  ➜  skadi git:(master) ✗ mongo         
  MongoDB shell version: 2.0.7
  connecting to: test
  > use skadi_development
  switched to db skadi_development
  > db.system.users.find()
  > db.addUser("joe", "passwordForJoe")
  { "n" : 0, "connectionId" : 191, "err" : null, "ok" : 1 }
  {
    "user" : "joe",
    "readOnly" : false,
    "pwd" : "dac588613249fe92703afb262ec53b82",
    "_id" : ObjectId("5030d5181cefbd2b04a99e30")
  }
  > db.system.users.find()
  { "_id" : ObjectId("5030d5181cefbd2b04a99e30"), "user" : "joe", "readOnly" : false, "pwd" : "dac588613249fe92703afb262ec53b82" }
  > exit
  bye

  ➜  skadi git:(master) ✗ rake db:reseed

  ➜  skadi git:(master) ✗ mongo         
  MongoDB shell version: 2.0.7
  connecting to: test
  > use skadi_development
  switched to db skadi_development
  > db.system.users.find()
  => Nothing

因此，当您尝试连接到数据库时，您的凭据将不再有效。

您可以在MongoHQ管理面板中查看。您可以通过访问Heroku，选择您的应用程序，单击资源并单击MongoHQ来找到它。然后单击Database users选项卡。

rake db:reseed曾经按照您的预期工作，但它随着mongoid的新版本而改变。要删除除system。*以外的所有集合，您可以使用rake db:purge。

您可能需要使用主分支，因为稳定版本中尚未提供该rake任务。或者只在代码中使用Mongoid.purge!，这可以在stable中使用。
