[Zope-dev] adding custom products programmatically

Hi, I created a new Product, "GalahadFile" and in it I created several Z Classes, GalahadImageFile for example. Now if i want to use python script to add a GalahadImageFile programmatically - what should I do? I add Image files this way: context.galahad.file_storage[str(org_id)].manage_addImage(str(new_id), file=new_contents, title=new_title) and I want to add GalahadImageFiles this way: context.galahad.file_storage[str(org_id)].manage_addGalahadImageFile(str(new_id), file=new_contents, title=new_title) What should I do for this? What methods should I add and where for this "manage_addGalahadImageFile" to work? TIA, Kaimar
