Question

我是Mongo的新手。我已经从this来源安装了Mongodb。我正在使用mongodb进行Rails应用程序。启动mongodb和rails后应用程序加载正常。但是，当我尝试登录时失败。当我尝试在rails控制台中执行某些操作时，会发生同样的事情。

这里是型号代码：

  def self.authenticate(email, password)
    user = find(:first, :conditions => {:email => email})
    if user && user.password_hash == BCrypt::Engine.hash_secret(password, user.password_salt)
      user
    else
     nil
    end
  end

在if user && user.password_hash == BCrypt::Engine.hash_secret(password, user.password_salt)

失败

这是一个简短的错误：

数据库命令＆＃39;创建＆＃39;失败：{＆＃34; ok＆＃34; =＆gt; 0.0，＆＃34; errmsg＆＃34; =＆gt;＆＃34;集合已经存在＆＃34;，＆＃34;代码＆＃34; =＆gt; 48 }

并且，完整的应用程序错误跟踪：

非常感谢任何帮助。

在检查代码和谷歌搜索后，我发现每个请求都发送了一个特殊字符。我的请求参数是这样的：

{  
   "utf8"=>"âœ“",
   "authenticity_token"=>"cAcdDOzfBgalF5em+97mTKw9DAjymfmEmG6hc+dDqhQ=",
   "email"=>"super_admin_user@test.com",
   "password"=>"[FILTERED]",
   "commit"=>"Login"
}

不确定是什么引发了'â''。但谷歌的一篇文章称，2.2系列中存在与此相关的错误，并且已在以后的版本中修复。

所以，我发现我的 mongoid 版本为2.2.1，一旦升级，问题就解决了。

注意：我是 mongoid 的新手，并提供了一个知识匮乏的解决方案。如果需要，请添加详细信息。
