Displaying the model's__unicode__ in django admin

Question

I would like to display the model's username in Django Admin interface but not very sure how to do it..

The models.py:      class Adult(models.Model):             user = models.OneToOneField(User)         fullname = models.CharField(max_length=100,                                     blank=True)         def __unicode__(self):             return self.user.username  Admin.py:      class AdultAdmin(admin.ModelAdmin):         list_display = ('??', 'Student_Name',)         search_fields = ['??',]      admin.site.register(Adult, AdultAdmin) 

What should go inside the ?? above ? I would like to display the unicode or the self.user.username? How do i do it? Need some guidance...

Answer 1

From the list_display documentation there are four things you can add there:

1. A field
2. Some method (a callable) that accepts one variable that is the instance for which the row is being displayed.
3. A string that is the name of a method or attribute defined in the model class.
4. A string that is the name of a method that is defined in ModelAdmin.

For your case we need #3 for list_display.

For search_fields its easier as you can use follow notation (__) to do lookups.

In the end we come up with this:

class AdultAdmin(admin.ModelAdmin):     list_display = ('__unicode__', 'Student_Name',)     search_fields = ['user__username']
