ruby-on-rails – 为什么我的mongoDB托管uri设置为mongoid.yml不

发布时间：2020-12-16 19:42:00 所属栏目：百科来源：网络整理

导读：我正在使用以下设置(这不工作)在我的mongoid.yml,我已经正确添加了MONGOLAB_URI环境变量到我的heroku环境： production: sessions: default: another: uri: %= ENV['MONGOLAB_URI'] % 我也尝试了以下不起作用： production: uri: %= ENV['MONGOLAB_URI'] %

我正在使用以下设置(这不工作)在我的mongoid.yml,我已经正确添加了MONGOLAB_URI环境变量到我的heroku环境：

production:
  sessions:
    default:
      another:
        uri: <%= ENV['MONGOLAB_URI'] %>

我也尝试了以下不起作用：

production:
  uri: <%= ENV['MONGOLAB_URI'] %>

这也不行：

production:
  sessions:
    default:
      uri: <%= ENV['MONGOLAB_URI'] %>

我在heroku推送上收到以下错误：

Running: rake assets:precompile
       There is a configuration error with the current mongoid.yml.
       Problem:
       No database provided for session configuration: :default.
       Summary:
       Each session configuration must provide a database so Mongoid knows where the default database to persist to. What was provided was: {"another"=>{"uri"=>nil}}.
       Resolution:
       If configuring via a mongoid.yml,ensure that within your :default section a :database value for the session's default database is defined.
       Example:
       __development:
       ____sessions:
       ______default:
       ________database: my_app_db
       ________hosts:
       __________- localhost:27017

       Asset precompilation completed (15.47s)

我在这里做错了什么？我遵循了mongoid.org的说明：

http://mongoid.org/en/mongoid/docs/installation.html

我正在使用mongoid 3.0.0.rc

解决方法

尝试这个

ENV['MONGOLAB_URI'] = ds053681.mongolab.com:97321

production:
  sessions:
    default:
      hosts: 
        - <%= ENV['MONGOLAB_URI'] %>
      database: testapp_production
      username: testappuser
      password: testpassword
