You can use dynamic finders:
Child.find_by_parent_id_and_name(parent.id, "Timmy")
But then again, if you already have the parent object, the common practice
is to setup the children association and get the child using it:
parent.children.find_by_name("Timmy")
Which IMO is more readable than the first example.
