New description:
I have three models whereas one has a custom `__init__()` method:
{{{
class Foo(models.Model):
my_foo = models.CharField(max_length=1000)
class Bar(models.Model):
bar1 = models.CharField(max_length=1000, default="")
bar2 = models.BooleanField(default=False)
foo = models.ForeignKey(Foo, on_delete=models.CASCADE)
def __init__(self, *args, **kwargs):
super(Bar, self).__init__(*args, **kwargs)
print("check")
self._original_bar1 = self.bar1
self._original_bar2 = self.bar2
class Baz(models.Model):
bar = models.ForeignKey(Bar, on_delete=models.CASCADE)
}}}
Creating a Foo object and a corresponding Bar object (via the admin
interface) works fine.
**However, when I delete the Foo object, this results in an endless loop
of the `__init__()` method.**
If I rewrite the models slightly as
{{{
from django.db import models
class Foo(models.Model):
my_foo = models.CharField(max_length=1000)
class AbstractBar2(models.Model):
bar2 = models.BooleanField(default=False)
def __init__(self, *args, **kwargs):
super(AbstractBar2, self).__init__(*args, **kwargs)
print("check")
self._original_bar2 = self.bar2
class Meta:
abstract = True
class AbstractBar1(models.Model):
bar1 = models.CharField(max_length=1000, default="")
def __init__(self, *args, **kwargs):
super(AbstractBar1, self).__init__(*args, **kwargs)
print("check")
self._original_bar1 = self.bar1
class Meta:
abstract = True
class Bar(AbstractBar1, AbstractBar2):
foo = models.ForeignKey(Foo, on_delete=models.CASCADE)
class Baz(models.Model):
bar = models.ForeignKey(Bar, on_delete=models.CASCADE)
}}}
it errors out on
{{{
