Django AttributeError:“Alias”对象没有属性“url”

Question

我刚写完我的英雄应用程序模型：

这是我的模型.py我的英雄应用程序的文件：

从django.db公司导入模型

# 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)

我调整了我的设置.py已安装应用下的文件：

^{pr2}$

然后我调整了我的管理员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)

在命令提示符下，我输入了python管理.pymakemigrations和我得到这个错误-“AttributeError:'Alias'对象没有属性'url'：

这是什么意思？我该怎么解决它？我看过StackOverFlow上的其他类似问题，但我不知道如何解决它。在

Answer 1

你应该换衣服

admin.site.register(Status, Alias)

到

^{pr2}$

此模型应在管理中通过单独的行添加。在

Answer 2

我终于在密码酒吧得到了答案！在

来自model.p的每个类都需要在管理员py. 在

所以答案是：

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)
