Admin panel and url handling as Primary Key

[guruyaya]

The admin panel cannot get a url as a primary key of a model.
I can actually understand why this happens, and that makes me more
thrilled to help. Take this model for example:
class Url(models.Model):

url = models.CharField(max_length=600, primary_key=True)
rate = models.IntegerField(null=True, blank=True)
class Admin:

pass

in the case Url.url=​http://yahoo.com' (had to add slashes to avoid
being marked as a spammer on the ticket system, but the point should
be understood
As the primary key is a url, the relational link inside the admin
panel, becomes absolute. I cannot use the admin panel to rate it.
What do you think of that?

Oh, it does not work when I set this field as a URLField.

Reformatted the code in the example:

class Url(models.Model):
    url = models.CharField(max_length=600, primary_key=True)
    rate = models.IntegerField(null=True, blank=True)
    
    class Admin:
        pass

If the problem is you don't want duplicate URLs you can always add unique=True to the model instead of primary_key=True. Your model's __unicode__ method could escape the URL before displaying it, or you could add some sort of label field and use that for list_display_links instead of the URL itself.

This looks like a great way to create a security problem for yourself.

Ok, That's a really smart way of looking at this problem.
Think I'll stick to it. The way I see it, this ticket is closed.
