TypeError in Django mit Python 2.7

Question

Hey, neu nach Django und brauche Hilfe, wenn ich mein Modell der Admin-Oberfläche in Django hinzufügen erscheint es gut, aber wenn ich versuche, einen Eintrag in der Datenbank hinzufügen oder löschen:

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

ich eine google-Suche durchgeführt und das hinzugefügt:

def __str__(self): 
    return "" 

Zum Ende meiner User-Modell Klasse, aber ohne Erfolg. Nicht sicher, ob ich etwas in mein admin.py eingeben muss? Ich habe auch keine "add" -Methode in meiner Benutzerklasse, es gibt auch nichts anderes als die obige Methode zurück.

Danke für jede Hilfe!

Die Klasse User:

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 "" 

Und die einfache admin.py in/Users/

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

admin.site.register(User) 

Traceback:

Answer 1

In Ihrer MEDIA_ROOT Definition, Ihre ersetzen ändern haben Sie eine rohe Zeichenkette, da Sie sonst einen einzelnen Backslash ersetzen anstatt die beiden, die Sie meinen.

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