Question

No idea why this is not working. It’s the first time I am working with Mongo, but from all the docs I have read, this should work? Anyone have any idea what I am missing?

require 'rubygems'                                                                                                                                                                                      
require 'sinatra/base' 
require 'mongo_mapper'                                                                                                                                                                                  

  mongo_server = '127.0.0.1'                                                                                                                                                       
  mongo_database = 'inone'

  MongoMapper.database = mongo_database                                                                                                                                                                   

  # DB model                                                                                                                                                                                              
  class URLstore

    key :url_key, String                                                                                                                                                                                  
    key :url, String                                                                                                                                                                                      
  end                      

class URLnip < Sinatra::Base                                                                                                                                                                            
   get '/testmongo' do         
    nipurl = URLstore.new(:url_key => "abc", :url => "www.google.com")                                                                                                                                                                                                                                                                                                           
    nipurl.save  
  end
end

Opening the Mongo terminal I can see the DB get’s created

> show dbs
inone   0.203125GB

but doing this brings back no results at all

> db.inone.find()
> 

or

> db.inone.find({url : 'www.google.com'})
> 

same thing nothing.

Answer 1

Shouldn’t that be db.urlstore.find()? Or however MongoMapper changes the case. What does show collections in a Mongo shell say after you select the right database?
