Question

In my django app, I have some objects that cause the corresponding URL in the django admin to be non ascii. (for example: http://mysite/admin/myapp/myclass/Présentation/)

I can edit the object without any problem but when I save it I have the following error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 24: ordinal not in range(128), HTTP response headers must be in US-ASCII format

The strange thing is that the object is correctly saved into the database.

Does anybody know how the Django admin manages unicode? Any info, pointer or idea that can help to fix this problem would be appreciated.

Thanks in advance

Update: Here is the code of the Model

class Plugin(models.Model):
    """Some subcontent that can be added to a given page"""
    class Meta:
        ordering = ['ordering']

    name = models.CharField(max_length=32, primary_key=True)
    div_id = models.CharField(default='rightcol', max_length=32)
    published = models.BooleanField(default=True,
        help_text=_("If this is not checked, it is not displayed on the page."))
    ordering = models.IntegerField(default=1,
        help_text=_("plugins are sorted with this number in ascending order"))
    content = models.TextField(blank=True)
    registration_required = models.BooleanField(_('registration required'),
        help_text=_("If this is checked, only logged-in users will be able to view the page."))

    def __unicode__(self):
        return u"%s -- %s" % (self.name, self.div_id)

Update:
That’s clear that non-ascii character are not recommended in an URL. That’s the cause of my problem and I have changed that.

Does anybody know what is used by the Django admin to build the URL of an object. I guess that it is the primary key. Is it right? is there a way to force Django to use something else and to retrieve the object safely?

Answer 1

I am now using the default id as primary key for every class of my model. As a consequence, I don’t have forbidden characters in the url when accessing objects from the admin site.

I do recommend to keep the default id as primary key in most cases
