Hi guys,
I have a question. I am working on an application that i can use as a
starting point for my future projects.
I have a core application that has CommonFields abstract model defined as:
from django.db import models
from django.contrib.auth.models import User
class CommonFields(models.Model):
created = models.DateTimeField(editable=False, auto_now_add=True)
created_by = models.ForeignKey(User, related_name="created",
editable=False)
modified = models.DateTimeField(editable=False, auto_now=True)
modified_by = models.ForeignKey(User, related_name="modified",
editable=False)
deleted = models.DateTimeField(editable=False)
deleted_by = models.ForeignKey(User, related_name="deleted",
editable=False)
class Meta:
abstract = True
All other models inherit this one.
I want to populate this fields automatically, something
like auto_now_add=True but for *_by fields where i want to add current
user, is there any way that i could do this?
Yes.
See p257-263 of the first edition of Pro Django by Marty Alchin. He
discusses a custom field (CurrentUserField) and middleware to
auto-populate it whenever a model is saved. I see there is a second
edition recently released. I found the entire book to be very valuable.
