Hi all,
Let's say I have a model like so:
class Thing(models.Model):
is_master = models.BooleanField()
name = models.CharField()
Now I want to be sure that only one Thing is_master at any given time.
The rest of the Things must not be master and end users shouldn't be
able to make a sencond Thing master by mistake through the admin site.
As far as I can tell, I have to override my model's save() method, but
I'm not sure how well that will play with the automatic admin site...
Regards,
Guillermo
