If i have an N..N relationship between Site and User when I do the following:
@site.create user = @site.users.new() user.save
@site will end up with no user in site_ids.
Here is an example that will produce the issue:
class User include Mongoid::Document has_and_belongs_to_many :sites, :autosave => true end class Site include Mongoid::Document has_and_belongs_to_many :users, :autosave => true end @site= Site.create() @user= @site.users.new() @user.save @site= Site.last @site #<Site _id: 4e8cc21d390b7c802c000005, _type: nil, created_at: 2011-10-05 20:46:21 UTC, updated_at: 2011-10-05 20:46:21 UTC, user_ids: []> @user #<User _id: 4e8cc220390b7c802c000006, _type: nil, created_at: 2011-10-05 20:46:27 UTC, updated_at: 2011-10-05 20:46:27 UTC, site_ids: [BSON::ObjectId('4e8cc21d390b7c802c000005')] >
