Comment:
Replying to [ticket:14071 mnbayazit]:
> Create a model and add a field with primary_key=True
> Go into the django admin panel and change this primary key.
> A new entry is added with the new PK, but the old one remains as well.
>
> Sample model:
>
{{{
class FlatPage(Model):
title = CharField(max_length=50)
key = SlugField(max_length=50, primary_key=True, help_text="Do not
change.")
content = TextField()
created = DateTimeField(auto_now_add=True)
updated = DateTimeField(auto_now=True)
def __unicode__(self):
return self.title
class Meta:
app_label = 'app'
}}}
The primary key is exactly how the decision is made as to whether update
or create a new row.
Altering this behavior would be a fundamentally backwards incompatible
change.
