I have stores which are related to projects. I would like to allow users to create projects themselves. But I need to ensure that they only create projects where no such projects exist previously. Unlike other posts I have seen on the subject where a field can be made unique, in my case much of the info remains same. In other words, when someone looks up a store and add a project, they have to use a category, followed by other project attributes. One option is to show previous projects in a section (again not too sure how is this accomplished as I am already in a project form) but would prefer some sort of warning. Will appreciate some help.
