ruby-on-rails - Mongoid::Errors::Rails 控制台中没有 session 配置

Question

我克隆了 rails 应用程序(我们公司的项目)，然后安装了与 mongo db 和 mongoid gem 相关的所有内容。然后我运行 rake db:setup 然后 rails s。它工作正常，我可以访问所有站点并执行所有操作。但是我在 rails 控制台中遇到了问题。

每当我这样做时:

rails c

然后

User.first

我会收到这个错误

Loading development environment (Rails 4.1.1) irb(main):001:0> User.first Mongoid::Errors::NoSessionConfig: 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. from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/sessions/factory.rb:27:in create' from

仅供引用，这是我通过运行生成的 mongoid.yml

rails g mongoid:config

mongoid.yml

development:
  sessions:
    default:
      database: mongo_demo_development
    hosts:
      - localhost:27017
    options:        
 options:

test:
  sessions:
    default:
      database: mongo_demo_test
      hosts:
        - localhost:27017
      options:
        consistency: :strong      
        max_retries: 1
        retry_interval: 0

我一直在寻找谷歌和一些博客，无法弄清楚如何解决这个问题。
除此之外，我们不使用 Rspec tho。

Answer 1

更改您的 config/application.rb 文件:

替换它 Bundler.require(*Rails.groups)

到它 Bundler.require(*Rails.groups(assets: %w(development test)))
