I know, I know, they''re not allowed to. But here''s my problem. I''ve got a really simple model with two fields, name and price, which I want to show in a form select drop-down. "collection_select" takes a ''text_method'' parameter, which is the method in the model that gets its value placed in the <option> tag.
