Hello,
I am trying to construct a lookup based on params submited.
possible urls…
/gadgets?product_id=1
/gadgets?product_id=1&product_group_id=2
/gadgets?product_location_id=5
/gadgets?product_id=1&product_location=5
…
How do I write a universal lookup method ?
Gadget.find_by_product_id
Gadget.find_by_product_id_and_product_group_id
Gadget.find_by_product_location_id
Gadget.find_by_product_id&product_location_id
I want find_by… to include only submitted params from a set of
possible options.
Essentially I want find a way to avoid writing many if and else and
wonder if anyone knows an easier and better approach.

You may find that the hash form of :conditions is the easiest way to
do this.
