Infinite loop caused by ordering Django

Question

When I try to delete a record from my model I have this error:

Infinite loop caused by ordering

class Empresa(MPTTModel):
    nombre = models.CharField(max_length=35, unique=True, db_index=True)
    parent = TreeForeignKey('Empresa', blank=True, null=True, related_name='children')
    nivel = models.PositiveIntegerField(default=1)
    class MPTTMeta:
        order_insertion_by = ['nivel']
    class Meta:
        ordering = ['parent__id']

Thanks in advance

Answer 1

have you tried to use self ?

 parent = TreeForeignKey('self', blank=True, null=True, related_name='children'

and remove

`ordering = ['parent__id']`
