> Interesting question. You COULD try the following:

> for store in Tienda.objects.all():
> self.list_display.append('stock_tienda_{id}'.format(id=store.id))
>
> this would give you the list of existing stores at server init time.

> something like this:
>
> def __getattr__(self, attr):
> base = 'stock_tienda_'
> if attr[:len(base)] == base:
> return
> Product.objects.filter(tienda=Tienda.objects.get(id=attr[len(base):]))
> return super(Product, self).__getattr__(self, attr)
>
> this should make the ModelAdmin's hack work
>
> finally, you need a way to add new columns for newly created stores, so
> maybe a post_save signal on Tienda objects
>
> @receiver(post_save, sender=Tienda)
> def add_to_product_list_display(sender, instance, new, **kwargs):
> if new:
> # I don't know how to get the ModelAdmin's instance for a given
> class,
> # but it must be something in django.contrib.admin.site
> product_admin.list_display.append('stock_tienda_{id}'.format(id=
> instance.id))
>
> you probably need another listener before .delete of stores, and I'm not
> certain the __getattr__ hack will work, but this sounds interesting.

> Please try on those lines, and let me know if this worked, I'm most
