I discovered this rather odd bug when I added authorization to my application. I noticed that when I added an extra iteration on a relationship in the authorization code, strange things happened in my view - references in the relationships multiplied!
I reproduced the issue as follows:
class Foo include Mongoid::Document has_and_belongs_to_many :bars, :class_name => 'Bar', :inverse_of => :foos end
class Bar include Mongoid::Document has_and_belongs_to_many :foos, :class_name => 'Foo', :inverse_of => :bars end
require 'mongoid' require './foo' require './bar' Mongoid.database = Mongo::Connection.new('localhost','27017').db('bugs') Mongoid.master.collections.reject { |c| c.name =~ /^system/}.each(&:drop) # Clean sheet foo = Foo.create foo.bars << Bar.create puts foo.bars.count # 1, as expected foo = Foo.first puts foo.bars.to_a.count # 1, as expected puts foo.bars.to_a.count # 1, as expected foo = Foo.first bar = Bar.first puts foo.bars.include?(bar) # true, as expected puts foo.bars.to_a.count # 1, as expected puts foo.bars.to_a.count # 2, not expected!
