AutoOneToOne doesn't work
System
OS: Linux Python: 3.5.1 Django: 1.9.5 Annoying: 0.9.0
Example
From README.md.
from annoying.fields import AutoOneToOneField
class MyProfile(models.Model):
user = AutoOneToOneField(User, primary_key=True)
home_page = models.URLField(max_length=255, blank=True)
icq = models.IntegerField(blank=True, null=True)
Description
I have try your example but it doesnt't work. I have no error messages. The field works lika a regular OneToOne field.
It is not working for me either.
class Alpha(models.Model):
...
class Beta(models.Model):
alpha = AutoOneToOneField(Alpha, primary_key=True, on_delete=models.CASCADE)
I created an Alpha object and no corresponding Beta object was created.
@pymarco I'm just seing this but AutoOneToOneField won't create a related object unless you try to access it.
a = Alpha.objects.create()
Beta.objects.count()
# 0
a.beta
# <Beta: Beta object>
Beta.objects.count() # 1
@littlehome-eugene We are going to need more details than that to figure out what is not working for you...
Same here. Django 1.11.2, annoying 0.10.3.
Under some circumstances objects are being created, but what those are I haven't figured out yet.
Not working for me either. Django 1.11.6, python 2.7, annoying 0.10.3.
@eduardocesar @moorchegue I don't see how we can possibly help you without more details... Did you read my previous comment ?
@arthurio I've tried to access the related object after the creation of the primary object and did not appear. With some investigation, it seems that it was a boolean field in the related object that was preventing it's creation.
Doesn't work for me either:
class PatientRecord(models.Model):
checkup_interval = models.IntegerField(default=180)
class Patient(models.Model):
name = models.CharField(max_length=64)
# date_of_birth = models.DateField()
record = AutoOneToOneField(PatientRecord, on_delete=models.CASCADE)
registration_date = models.DateField()
last_visit = models.DateField(blank=True, null=True)
# Keep track of how many times we're sending messsages to people
# to make sure we don't spam them
appointment_reminder_attempt = models.IntegerField(default=0)
email_address = models.EmailField(blank=True, null=True)
Creating a Patient object does not automatically create a PatientRecord. I've tried creating via the admin as well as via the shell. Doesn't seem to work either way.
Django==2.0 django-annoying==0.10.3
@arthurio Thanks, accessing the related object creates it.

Is primary_key=True required for this to work?
My model is defined as such:
class CrmCategory(models.Model):
stats_list_direct = AutoOneToOneField('CrmCategoryStatsList',
null = True,
related_name = 'direct_category',
help_text = 'What stats to list, as defined by this category directly.')
stats_list_union = AutoOneToOneField('CrmCategoryStatsList',
null = True,
related_name = 'union_category',
help_text = 'An or''ing of the direct stats, and the children''s stats_list_union')
And yet when I access it, I get a None:
cat = CrmCategory.objects.all().first()
print('union', cat.stats_list_union)
@albrnick You want to put the AutoOneToOneField on the CrmCategoryStatsList model instead:
class CrmCategoryStatsList(models.Model):
category = AutoOneToOneField(...)
