Python ile Django'da TypeError 2.7

Question

Hey, Django'ya yeni bir model ekliyorum ve desteğe ihtiyaç duyduğumda, modelimi Django'daki yönetici arayüzüne eklediğimde iyi görünüyor, ancak veritabanına bir giriş eklemeye veya silmeye çalıştığımda şunu elde ederim:

TypeError at /admin/Users/user/add/  
    coercing to Unicode: need string or buffer, tuple found 

Ben bir google arama yapıp ekledi:

def __str__(self): 
    return "" 

benim Kullanıcı modeli sınıfının amaçla ancak başarılı. Admin.py sayfama bir şey girmem gerekiyor mu? Kullanıcı sınıfımda "eklenti" yöntemim yok, ayrıca yukarıdaki yöntemden başka bir şey de vermiyor.

Yardımlarınız için teşekkürler!

Kullanıcı Sınıfı:

class User(models.Model): 
GENDER_CHOICES = (
     ('M', 'Male'), 
     ('F', 'Female'), 
    ) 

username = models.CharField(max_length=30) 
email = models.EmailField() 
password = models.CharField(max_length=30) 

birth_date = models.DateField() 
description = models.CharField(max_length=200) 
gender = models.CharField(max_length = 1, choices = GENDER_CHOICES, default = "M") 
image = models.ImageField(upload_to="media/photos/") 
signupIP = models.IPAddressField() 
privateOrPublic = models.BooleanField(default=1) 

def __str__(self): 
    return "" 

Ve In/Kullanıcılar basit admin.py/

from Users.models import User 
from django.contrib import admin 

admin.site.register(User)

, senin için değiştir değiştirmek aksi taktirde ham bir dize var, aksi halde sen demek istediğin ikiden ziyade bir tek ters eğik çizgi yerine geçeceksin.

MEDIA_ROOT = os.path.join(os.path.dirname(file), "media").replace(r"\\", "//")
