Currently, I am overriding the save() method to keep records of all
changes made to objects. I've created a simplified example below.
I have two questions:
1) Is there an obvious better way?
2) When comparing the 'status_id' fields, they always are unequal even
when the status wasn't changed during modification. Any reason why?
Using the shell, they both return int which compare equally.
I'm using the following (simplified) models:
### start models.py ###
from django.db import models
class Note(models.Model):
created = models.DateTimeField(auto_now_add=True)
message = models.CharField(maxlength=1000)
def __str__(self):
return self.message
class Admin:
pass
class Status(models.Model):
name = models.CharField(maxlength=50)
def __str__(self):
return self.name
class Admin:
pass
class Order(models.Model):
created = models.DateTimeField(auto_now_add=True)
customer_name = models.CharField(maxlength=100)
status = models.ForeignKey(Status)
def save(self):
if self.id: # on update
note = Note()
note.message = ""
orig = Order.objects.filter(pk=self.id)[0]
for f in ['customer_name', 'status_id']:
if self.__dict__[f] != orig.__dict__[f]:
note.message += "%s was: %s; " % (f, orig.__dict__[f])
note.save()
super(Order,self).save()
def __str__(self):
return self.customer_name
class Admin:
pass
### end models.py ###
Thanks for your time.
