3288	ForeignKey to 'self' and select_related() = infinite recursion	Max Derkachev <mderk@…>	Philippe Raoult	"Maybe it's a variant of #3045 bug.
The [simplified] case is
{{{
#!python
class Foo(models.Model):
    parent = models.ForeignKey('self')
    
    class Meta:
       db_table = 'foos'

foo = Foo.objects.select_related().get(pk=1)
}}}

That leads to infinite recursion in django.db.models.query.fill_table_cache. The bottom of the stack trace is:
{{{
  ........ many many lines ............
  File ""/home/maxim/dproject/django/db/models/query.py"", line 684, in fill_table_cache

    return self.to._meta.get_field(self.field_name)
  File ""/home/maxim/dproject/django/db/models/options.py"", line 98, in get_field
    if f.name == name:
