Django Attribute: ‚Alias‘ Objekt hat kein Attribut ‚Urls‘

Question

Ich habe App mein Modell für meine Helden gerade fertig geschrieben out:

Hier ist meine models.py Datei für meine Helden App:

von django.db Importmodelle

# Create your models here. 
class Hero(models.Model): 
    codename = models.CharField(max_length = 30) 
    profilePic = models.ImageField(blank=True) #blank makes this optional 

    def __str__(self): 
     return (self.codename) 

class Stats(models.Model): 
    heroID = models.ForeignKey('Hero') 
    height = models.CharField(max_length = 10) 
    weight = models.CharField(max_length = 10) 
    STATS_CHOICES = (
    ('1', 'Extremely Low'), 
    ('2', 'Very Low'), 
    ('3', 'Low'), 
    ('4', 'Average'), 
    ('5', 'Good'), 
    ('6', 'Above Average'), 
    ('7', 'High'), 
    ('8', 'Very High'), 
    ('9', 'Super Human'), 
    ('10', 'Above and Beyond')) 
    powers = models.CharField(max_length = 5, choices = STATS_CHOICES) 
    intelligence = models.CharField(max_length = 5, choices = STATS_CHOICES) 
    durability = models.CharField(max_length = 5, choices = STATS_CHOICES) 
    strength = models.CharField(max_length = 5, choices = STATS_CHOICES) 
    speed = models.CharField(max_length = 5, choices = STATS_CHOICES) 

    def __str__(self): 
     return (self.heroID) 

class Team(models.Model): 
    name = models.CharField(max_length = 25) 
    leader = models.IntegerField 
    address = models.TextField 
    description = models.TextField 
    members = models.TextField 

class Status(models.Model): 
    heroID = models.ForeignKey('Hero') 
    missionID = models.IntegerField 
    TeamID = models.IntegerField 

    def __str__(self): 
     return (self.heroID, self.missionID, self.TeamID) 

class Alias(models.Model): 
    heroID = models.ForeignKey('Hero') 
    firstName = models.CharField(max_length = 25) 
    surname = models.CharField(max_length = 25) 
    formerCodeNames = models.TextField 
    occupation = models.CharField(max_length = 30) 
    address = models.TextField 
    citizenship = models.CharField(max_length = 40) 
    species = models.CharField(max_length = 40) 

    def __str__(self): 
     return (self.heroID, self.firstName, self.surname) 

eingestellt ich meine settings.py Datei unter den installierten Apps:

INSTALLED_APPS = [ 
    'django.contrib.admin', 
    'django.contrib.auth', 
    'django.contrib.contenttypes', 
    'django.contrib.sessions', 
    'django.contrib.messages', 
    'django.contrib.staticfiles', 

    #custom apps 
    'heroes', 
] 

Und dann stellte ich meine admin.py Datei:

from django.contrib import admin 

# Register your models here. 
from .models import Hero, Stats, Team, Status, Alias 

admin.site.register(Hero, Stats) 
admin.site.register(Team) 
admin.site.register(Status, Alias) 

In der Eingabeaufforderung ich aus getippt: Python manage.py makemigrations und ich diesen Fehler hätte - „Attribut:‚Alias‘Objekt hat kein Attribut‚Urls‘ „:

Was bedeutet das und wie kann ich es beheben? Ich habe andere ähnliche Probleme auf StackOverFlow untersucht, aber ich habe nicht verstanden, wie ich es beheben kann.

Answer 1

Ich bekam endlich meine Antwort bei einem Treffen in der Codebar!

Jede Klasse von model.p muss in admin.py in einer separaten Zeile stehen.

Die Antwort ist also:

from django.contrib import admin 

# Register your models here. 
from .models import Hero, Stats, Team, Status, Alias 

admin.site.register(Hero) 
admin.site.register(Stats) 
admin.site.register(Team) 
admin.site.register(Status) 
admin.site.register(Alias)
