Heroku＆MongoHQ：ActionView :: Template :: Error（操作：＃<Moped :: Protocol :: Commands :: Authenticate failed with error“auth failed”）

Question

我有一个Rails 3应用程序，成功部署到MongoID 3 Heroku（使用MongoHQ） - 但后来发生了一些事情（无法确定它到底是什么），并且构建开始在Heroku上崩溃。

所以这是我的错误：

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

是什么使这更难以调试的是，它的工作在本地主机上就好了。 现在我正在想出这可能是什么。

我最近在努力与Heroku的，并因此我想我应该有DB驱动程序的选择&服务的正确设置（使用新的YML方案+红宝石1.9.3中的Gemfile） 。

当我运行heroku config --app app_name我得到

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mongoid.yml看起来是这样的：

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

的Gemfile是这样的：

gem 'bundler', '1.2.0.rc' 

ruby '1.9.3'

Answer 1

的问题是，您的身份验证凭证不再正确。具体而言，您尝试认证的用户不再存在。

原因是，当你做一个rake db:reseed所有的数据被删除，包括数据库级别的用户。

例子：

➜ 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 

所以当您尝试连接到数据库，你的证书不再有效。

你可以在你的MongoHQ管理面板中检查。你可以通过Heroku找到它，选择你的应用程序，点击资源并点击MongoHQ。然后点击数据库用户选项卡。

rake db:reseed用于按照您的预期工作，但它随新版本的mongoid而改变。为了移除除system *之外的所有集合，您可以使用rake db:purge。

您可能需要使用主分支，因为该耙机任务在稳定版本中尚不可用。或者在你的代码中使用Mongoid.purge!，这个工作稳定。
