Hey all, Let''s say you are not going to use an html form. Rather the user will input data in a third-party application that will communicate with the rails controller through http requests, but serves as a replacement to the html.

I want to write a validate routine to check to enforce that a position must be unique in a category. (In another category, it doesn''t have to and shouldn''t need to be unique.)
