Mongoid sessions not found - mongodb

Question

Trying out a Sinatra | Mongoid 3. I run into the following error, whenever I attempt to save to the database.
Mongoid::Errors::NoSessionsConfig:
Problem:
No sessions configuration provided.
Summary:
Mongoid's configuration requires that you provide details about each session that can be connected to, and requires in the sessions config at least 1 default session to exist.
Resolution:
Double check your mongoid.yml to make sure that you have a top-level sessions key with at least 1 default session configuration for it. You can regenerate a new mongoid.yml for assistance via `rails g mongoid:config`.
Example:
development:
sessions:
default:
database: mongoid_dev
hosts:
- localhost:27017
from /Users/rhodee/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1/gems/mongoid-3.0.13/lib/mongoid/sessions/factory.rb:61:in `create_session'
I've already confirmed the following:
Mongoid.yml file is loaded
The hash contains correct environment and db name
Using pry the return value from the Mongoid.load! method returns:
=> {"sessions"=>
{"default"=>
{"database"=>"bluster",
"hosts"=>["localhost:27017"],
"options"=>{"consistency"=>"strong "}}}}
If it's any help check, I've added the app.rb file and mongoid.yml file as well.
App.rb
require 'sinatra'
require 'mongoid'
require 'pry'
require 'routes'
require 'location'
configure :development do
enable :logging, :dump_errors, :run, :sessions
Mongoid.load!(File.join(File.dirname(__FILE__), "config", "mongoid.yml"))
end
Mongoid.yml
development:
sessions:
default:
database: bluster
hosts:
- localhost:27017
options:
consistency: strong

require 'sinatra'
require 'mongoid'
require 'pry'
require 'routes'
configure :development do
enable :logging, :dump_errors, :run, :sessions
Mongoid.load!(File.join(File.dirname(__FILE__), "config", "mongoid.yml"))
end
get '/db' do
"db: " << Mongoid.default_session[:moped].database.inspect
end
I put together an example, and it is working just fine for me. Probably your problem is something else, like the config file not having read access or something else. Anyways my config file is identical as yours and this is my sinatra file, and it works fine.
