I have a text box field that I''m using the populate my habtm relationship between widgets and gadgets. I do not, however, want a gadget to be linked more than once to a widget. I figure the best way to do this is using validation in the model, but I''m not sure how I would go about validation using habtm. How could I achieve this? Thanks in advance!
