models.SlugField() is_active = models.BooleanField(default=True) site = models.ForeignKey(Site) parent = models.ForeignKey('self', blank=True, null=True) class Translation(TranslationModel): title = models.CharField(max_length=100) label = models.CharField(max_length=100, blank=True, null=True) description = models.TextField(blank=True, null=True) disclaimer = models.TextField(blank=True, null=True) class Meta: unique_together = (("slug", "parent")) def __unicode__(self): return self.title if self.title is not None else _("No translation") </code></pre> <p>and following is my admin.py </p> <pre><code>class MainAdmin(MultilingualModelAdmin): ''' Multilingual interface for Main category ''' class ListAdmin(MultilingualModelAdmin): ''' Multilingual interface for Main category ''' admin.site.register(Main, MainAdmin) admin.site.register(List, ListAdmin) </code></pre> <p>When I access my admin panel, I can see the model, list of items, add new items but when I try to edit an existing item or delete one I get the followng error</p> <pre><code> Environment: Request Method: GET Request URL: http://mazban.com/admin/category/main/1/ Django Version: 1.3 Python Version: 2.6.1

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
