Hi, The error I get is the following:
AttributeError at /admin/jewellery/ring/add/ 'Ring' object has no attribute '_get_subtype' Hence why I tried adding in my own subtype. To be honest, I am not trying to achieve anything other than to make the error go away :) Having had a look at the satchmo source code though, I did get to thinking that subtypes might be a good way to use custom views for certain product types further on down the line, but in this particular instance I don't think I will need that.
