Hi, I''m trying to create a simple chess game in Rails. Each square on the board is a div with its own id. Pieces are images. I assign a CSS class to squares based on whether they are empty (they can accept a piece of either color) or they have a piece image inside the div (they can only accept a piece of the opposite color for capturing purposes). Moving pieces to empty squares works fine. Moving pieces to capturing squares works fine. In both cases my controller action is called because the drop "worked" and I update my internal knowledge of the board position. But moving a piece to a div that does not have an acceptable class element does not revert the piece back to where it came from. Indeed I can move a piece "off the board" into the surrounding <body> element and the piece sticks there, instead of reverting to its original place. Any idea how to get the <%= drop_receiving_element ....%> l to revert the drag if it lands on a div without an acceptable CSS class? Thanks!
