Mongoid::Errors::NoSessionConfig in rails consolse

Question

I clone rails app (our company project) and then install everything that related to mongo db and mongoid gem. Then I run the rake db:setup and then rails s. Its working fine, I can access all the sites and do everything. But I got problem in the rails console.

Whenever I do this:

rails c

then

User.first

I will get this error

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 /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/sessions.rb:65:in with_name' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/sessions.rb:105:in mongo_session' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/sessions.rb:121:in collection' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/sessions/options.rb:161:in method_missing' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/contextual/mongo.rb:263:in initialize' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/contextual.rb:53:in new' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/contextual.rb:53:in create_context' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/contextual.rb:35:in context' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/contextual.rb:20:in first' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/mongoid-4.0.0.beta2/lib/mongoid/findable.rb:122:in first' from (irb):1 from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.1.1/lib/rails/commands/console.rb:90:in start' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.1.1/lib/rails/commands/console.rb:9:in start' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.1.1/lib/rails/commands/commands_tasks.rb:69:in console' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.1.1/lib/rails/commands/commands_tasks.rb:40:in run_command!' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/railties-4.1.1/lib/rails/commands.rb:17:in ' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:247:in require' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:247:inblock in require' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:232:in load_dependency' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:247:inrequire' from /Users/rizalmuthi/Documents/Sites/WORK/tapway/bin/rails:8:in <top (required)>' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:241:inload' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:241:in block in load' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:232:inload_dependency' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activesupport-4.1.1/lib/active_support/dependencies.rb:241:in load' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in require' from /Users/rizalmuthi/.rbenv/versions/2.1.1/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in require' from -e:1:in'irb(main):002:0>

And FYI, this is the mongoid.yml that I generated by run

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

I have been looking all over google and some blogs, could not figure it out how to fix this. Besides that, we dont use the Rspec tho.

Answer 1

change your config/application.rb file:

replace it Bundler.require(*Rails.groups)

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