/home/nikunj/.rvm/gems/ruby-1.9.3-p385/bundler/gems/mongoid-d52c33bce36a/lib/mongoid/sessions/factory.rb:27:in create': (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
