Class attribute - help

Hugo Oliveira	Monday 10 September 2007 5:29:47 pm Hi First of all I'd like to apologize if this topic is in the wrong place. I've got a class with an attribute that (ideally) could be one of 2 things: a hyperlink or a file. Is there a way to define a class to harbor such a constraint? This attribute should never be both at the same time. Is there a way to do this with just a class definition? Thanks in advance.
Olivier Ouin	Monday 17 September 2007 8:25:06 am I think it's not possible to do it only with a new class. For me, the simpliest way is to create a class with the 2 attributes, with a custom edit template that allow to input only one of them (javascript validation prior to post, by example). More sophisticated, you can deleguate creation of these objects to a custom module, calling for a custom template. Another solution could be the custom datatype which will reject validation if link and file are submited, but it's maybe a kind of overkill.
