我剛剛寫完了我的模型，我的英雄應用：Django的AttributeError的：「別名」對象有沒有屬性「的網址」
這裏是我的英雄我的應用程序文件models.py：
從django.db進口車型
# 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)
我調整我的settings.py文件中已安裝的應用下：
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
#custom apps
'heroes',
]
然後我調整我的admin.py文件：
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)
在命令提示符我輸入了：蟒蛇manage.py makemigrations，我得到這個錯誤 - 「AttributeError的：‘別名’對象有沒有屬性‘的網址’ 「：

這是什麼意思，我該如何解決？我查看了StackOverFlow上的其他類似問題，但我不明白如何解決它。
是否'Alias'模型模型'ForeignKey'爲''的狀態，如果是。你想在管理中創建內聯嗎？ –
「register」的第二個參數應該是'ModelAdmin'的子類，而不是'Model'的子類！ – schwobaseggl
我不太明白你在說什麼，schwobaseggl。你指的是Admin.py文件嗎？哪個是第二個參數？ –
