ArgumentError on example query

[PenguinOfWar]

Hi,

Using your basic example query (modified slightly to fit my class name):

Locations.all(:address.near => {:origin => 'Portland, OR', :distance => 5.mi}, :order => [:address_distance.desc])

Throws an argument error:

+options[:field]+ entry :address_distance does not map to a property in Locations
file: query.rb location: assert_valid_fields_without_operator line: 805

Full backtrace:
