How to show all fields of model in admin page?

Question

here is the models page

In this picture, only the title shows up on here, I used:

 def __unicode__(self):
        return self.title;

I like this answer and thought I'd post the complete admin.py code (in this case, I wanted all the User model fields to appear in admin)

from django.contrib import admin
from django.contrib.auth.models import User
from django.db.models import ManyToOneRel, ForeignKey, OneToOneField


MySpecialAdmin = lambda model: type('SubClass'+model.__name__, (admin.ModelAdmin,), {
    'list_display': [x.name for x in model._meta.fields],
    'list_select_related': [x.name for x in model._meta.fields if isinstance(x, (ManyToOneRel, ForeignKey, OneToOneField,))]
})

admin.site.unregister(User)
admin.site.register(User, MySpecialAdmin(User))
