I’m building a prototype where users are allowed to post URLs.
But I don’t want the same URL to be posted multiple times. To prevent this, is easy.
However what I would like is, when a URL has already been posted by a user A, then when it is attempted to be posted again by a user B (and detect that it already exists), to be able to update the original record and add user B as a “contributor” (or something like that).
Is it possible?
thank you so much!
