Enforce no duplicates on an aspect property

rob2020 — Thu, 18 Jun 2009 14:41:45 GMT

Hi,I have defined a custom content type of "product" which has a mandatory custom aspect of "sku" ie SKU being the product identifer and the primary key of a product. I'd like to ensure that this SKU aspect is unique across that content type (product) ie no duplicate product documents are allowed in

Two options come to mind. First, you could write a custom constraint for the SKU property that would check to see if the value was already being used on an object of the product type.

A second option would be to use use a behavior to check to see if the SKU has already been set on another product object.

I think the constraint might be the first thing to try.

Thanks Jeff.

I will use your book which is sat on my desk right now as a reference whilst I give one of these a try. I'm a big fan of your book by the way. It's fast tracked me into Alfresco.

Cheers
