The answer to seemingly broken rails behavior is usually "duh..I
should have realized that!"
My link_to syntax was fine. The HTTP put was successfully finding the
correct controller method, but that method was performing a redirect
that was failing (in a rather opaque way to me) because in this
particular code path I did not initialize an instance variable (@item)
that was the parameter to the redirect because I was bypassing a
form_for...submit action that otherwise passes in the item.id:
redirect_to edit_item_cost_path(@item, @cost)
It appears that this RESTful helper fails with a not-too-insightful
error when passed a bogus parameter.
Thanks everyone who pitched in with suggestions and pointers.
