Finders should support associations properly
Reported by Dirkjan Bussink | July 24th, 2008 @ 01:38 AM
It should be possible to do the following:
Address.all(:person => Person.first)
Or:
Address.all(Address.person => Person.first)
Currently someone has to do something like:
Address.all(Address.person.id => Person.first.id)
This is not only ugly, but also problematic for stuff like composite keys. Furthermore, the user has to handle stuff like Person.first being nil, which should also work automatically.

Seems close to working btw, it fails on:
NoMethodError in 'CostCenter with regard to generating timecards should be able to retrieve all registrations for a certain cost center'
private method `gsub' called for nil:NilClass

This is because the property in there is a DataMapper::Query::Path and not a Property object.
