When calling #find on a many to many relation, it's actually not performing any scoping at all, so simply if the id matches it will return the document.
Example to reproduce:
class AssetLibrary include Mongoid::Document has_and_belongs_to_many :writers, :class_name => 'User', :inverse_of => :writable_asset_libraries has_and_belongs_to_many :readers, :class_name => 'User', :inverse_of => :readable_asset_libraries end class User include Mongoid::Document has_and_belongs_to_many :writable_asset_libraries, :class_name => 'AssetLibrary', :inverse_of => :writers has_and_belongs_to_many :readable_asset_libraries, :class_name => 'AssetLibrary', :inverse_of => :readers end user = User.create writable = user.writable_asset_libraries.create readable = user.readable_asset_libraries.create user.writable_asset_libraries.find(readable.id)
Note the find generates a MongoDB query of:
MONGODB mongoid_sandbox['asset_libraries'].find({:_id=>BSON::ObjectId('4e85dda98ad548383e000003')}).limit(-1).sort([[:_id, :asc]])
This should at least have the scope of the ids array from writable_asset_libraries_ids.
