On a recent project, i was able to auto generate many things via hooking into the token module. I noted that it is required for ubercart - is there a way it can be hooked into to auto-generate an SKU. This could be as simple as a string of letters followed by the node-id (the only issue would be that non-product nodes would not provide for sequential numbering - product id perhaps?)
I am not sure how relevant/widespread its application would be. For the project i am working through, it would be as it is for an artist's work.
I was also thinking in terms of having different SKUs for attributes. For example, what i am trying to achieve is to have an original artwork and prints. There would only be one original (i am working though inventory control as well - stuck on both for now) and a select number of prints, if any. In this case, the prints SKU could have a -p added, for example, at the end.
Given that this would be the same for each product (artwork) i think i should be able to create a class to apply automatically for the attributes as well - this is for another thread, however - as are my current fumbling's with inventory control
