recursion - how to recursively group products by its category in django -


i have category model related , products model related category model.

category(models.model):     name = ...     subcategory = models.foreignkey(self, related_name="subcategory", null=true, blank=true)  product(models.model):     name = ....     category = models.foreignkey('category', related_name='productcategory')
