DEP 12 (Steering Council) Fully Adopted

[Andrew Godwin]

Hi everyone,

I am pleased to report that we've completed the extended approval process for 
DEP 12, which was needed since it was a governance change. Both the Technical 
Board and the DSF Board voted to not require a vote from the membership on the 
change, so it is now officially adopted and I will begin implementation 
immediately (which is mostly going to be renaming things).

Thanks everyone for your comments and help refining this DEP! You'll be hearing 
more from myself or one of the other Steering Council members soon about our 
first proper "call for feature proposals", as it'll be timed right after the 
4.2 feature freeze in January.

Andrew

get_manager short ut function proposal

[Ramez Ashraf]

Hello everyone, 

I want to propose a helper function
`get_manager(parent_manager=None, *args, **kwargs)` 

A shortcut to return a manager, *args & **kwargs are passed to the manager 
.filter()
pass parent_manager to customize the parent manager, defaults to 
``Manager``.

it can be used like this 

from django.db.models import get_manager

class Person(models.Model):
# ...
authors = models.get_manager(role='A')
editors = models.get_manager(role='E')
special = get_manager(~Q(name="Roald Dahl"), role='E')
manager_with_counts = get_manager(parent_manager=PollManager, 
name="Roald Dahl")

Instead of the current 

class AuthorManager(models.Manager):
def get_queryset(self):
return super().get_queryset().filter(role='A')

class EditorManager(models.Manager):
def get_queryset(self):
return super().get_queryset().filter(role='E')

class Person(models.Model):
people = models.Manager()
authors = AuthorManager()
editors = EditorManager()
   ...

The first is more readable and nicer .. yeah ?
Code is working and ready at  github 

 ,  

Do i get +1(s) to move forward and create a ticket ?
