I'm having trouble with #with_extend.
I can extend methods from another module but I cannot continue chaining for
example association join.
class Garage < Sequel::Model
one_to_many :cars
end
class Car < Sequel::Model
one_to_many :seats
module Foo
def steer_car
association_join(:seats)
end
end
dataset_extend Foo
end
garage.association_join(:cars).with_extend(Car::Foo).steer_car # -> this
will give an error because association_join still thinks we are in Garage
model and there is no :seats association in Garage.
