Question

i am running into an issue with updates to nested attributes for referenced documents not being persisted

> u = User.first
 => #<User...
> u.changes
 => {} 
> u.profile.changes
 => {} 
> u.attributes = {:profile_attributes => {:weight => 8}}
 => {:profile_attributes=>{:weight=>8}} 
> u.changes
 => {} 
> u.profile.changes
 => {"weight"=>[14.0, 8.0]} 
> u.update
 => true 
> u.shipping_profile.changes
 => {"weight"=>[14.0, 8.0]}

update/update_attributes/save all do not persist the nested changes.
i have attr_accessible :profile_attributes declared in the user model.

what is needed for nested attributes to persist when the parent document is already persisted?

turns out its a mongoid issue. i submit a pull request with the failing test here https://github.com/mongoid/mongoid/pull/978 for anyone else having the same issue. im just manually saving/updating nested records until its resolved
