que estoy recibiendo esta respuesta anterior cuando intento para salvar algún objeto. Follwoing son mis versiones de la gema de MongoId y mongo, lo que creo que es un problema de su mongoid.yml pero no está seguro como mi yml está perfectamente bien

Usando BSON (1.3.1) Usando bson_ext (1.3.1) el uso de mongo (1.3.1) Instalación MongoId (2.1.9)

mongoid.yml

defaults: &defaults 
    host: localhost 

development: 
    <<: *defaults 
    database: gm_development 

test: 
    <<: *defaults 
    database: gm_test 
production: 
    host: <%= ENV['MONGOID_HOST'] %> 
    port: <%= ENV['MONGOID_PORT'] %> 
    username: <%= ENV['MONGOID_USERNAME'] %> 
    password: <%= ENV['MONGOID_PASSWORD'] %> 
    database: <%= ENV['MONGOID_DATABASE'] %> 
    uri: mongodb://username:password@staff.mongohq.com:10029/appid 

por favor, hágamelo saber si usted encuentra algo malo en este

Answer 1

intento:

u.save(:validate=> false) 

Answer 2

que publiqué mi objeto y recibiendo el error en Rails 3.0:

undefined method `[]' for false:FalseClass

pero funciona ahora encontrar después de cambiar mi código de:

save(false) 

a:

save(:validate=> false)
