Given a model
{{{#!python
from django.db import models
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
}}}
In django < 1.10
{{{#!python
In [1]: from polls.models import Question
In [2]: q = Question.objects.last()
In [3]: Question._default_manager
Out[3]: <django.db.models.manager.Manager at 0x7ff799637f28>
In [4]: q._default_manager
Out[4]: <django.db.models.manager.Manager at 0x7ff799637f28>
}}}
In django >= 1.10
{{{#!python
In [1]: from polls.models import Question
In [2]: q = Question.objects.last()
In [3]: Question._default_manager
Out[3]: <django.db.models.manager.Manager at 0x7f5e0721d4a8>
In [4]: q._default_manager
---------------------------------------------------------------------------
AttributeError Traceback (most recent call
last)
<ipython-input-4-2c5c6f28a506> in <module>()
----> 1 q._default_manager
AttributeError: 'Question' object has no attribute '_default_manager'
In [5]: q._meta.default_manager
Out[5]: <django.db.models.manager.Manager at 0x7f5e0721d4a8>
}}}
It's an intenden behaviour?
If so, it lacks a notice in releases note and/or manager docs.
I found it testing my project with django-paypal
(https://github.com/spookylukey/django-
paypal/blob/79b22278b658b2fc618771ca7c471ea398455147/paypal/standard/helpers.py#L24)
