rails环境mongoid连接问题 [英] rails environment mongoid connection issue

问题描述

我有rails app 3.2.17，部署在 staging 环境中，由unicorn 4.6.3监视bluepill 0.0.66使用mongid 3.1.5

 在故障安全期间发生错误响应：
问题：
无法找到名为default的会话的配置。 
摘要：
尝试创建新会话时，Mongoid找不到名称为default的会话配置。这是必要的，以了解连接所需的主机，端口和选项。 
解决方案：
仔细检查您的mongoid.yml以确保在会话密钥下存在default配置。如果您以编程方式设置配置，请确保配置哈希中存在默认。

）
 child_process.checks（：cpu_usage，
：every => 30.seconds，

）
 end 
 end 
 end 
  

我怀疑mongoid没有收到RAILS_ENV，但我不确定，我检查mongoid.yml中的缩进。另一个原因，我没有发现。/ / p>

解决方案

在/config/application.rb类型

  require'mongoid'
 
 Mongoid.load！（File.expand_path（'mongoid.yml'，'./config'）） 
  

它可能是通过初始化程序。

I have rails app 3.2.17, deployed in staging environment with unicorn 4.6.3 monitored by bluepill 0.0.66 using mongid 3.1.5

When I deploy for staging environment all works find including active_record except mongoid queries with result with following error:

Error during failsafe response: 
Problem:
  No configuration could be found for a session named 'default'.
Summary:
  When attempting to create the new session, Mongoid could not find a session configuration for the name: 'default'. This is necessary in order to know the host, port, and options needed to connect.
Resolution:
  Double check your mongoid.yml to make sure under the sessions key that a configuration exists for 'default'. If you have set the configuration programatically, ensure that 'default' exists in the configuration hash.

        process.monitor_children do |child_process|
            child_process.stop_command 'kill -QUIT {{PID}}'
            child_process.checks(:mem_usage,
                :every => 30.seconds,
                :below => 1024.megabytes,
                :times => [3,4]
            )
            child_process.checks(:cpu_usage,
                :every => 30.seconds,
                :below => 90,
                :times => [3,4]
            )
        end
    end
end

I suspect that mongoid is not receiving the RAILS_ENV, but I'm not sure, I check indentation in mongoid.yml. Should another reason that I not find out.

解决方案

in /config/application.rb type

require 'mongoid'

Mongoid.load!(File.expand_path('mongoid.yml', './config'))

It may be do it via initializer.
