Example:
class Project
include DataMapper::Resource
has n, :tasks
end
class Task
include DataMapper::Resource
....
end
Say I have object "p" (Project::Class) and object
"association" (:tasks). How can I determine that "association" is of
class Task and instantiate a Task object using datamapper?
In ActiveRecord, I can do the following:
new_object = p.class.reflect_on_association(association).klass.new
What is the Datamapper equivalent?
