访问管理员网站中的模型时出现问题

我已经创建了概要文件模型，它在django的管理网站上运行良好，显然，我尝试创建了一个非常复杂的模型，但我不断出错，无论如何，我决定简化流程，并创建了一个非常简单的模型。
models.py

from django.db import models
from django.conf import settings

# from django_countries.fields import CountryField

# from phone_field import PhoneField

class Profile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
    email = models.EmailField(blank=True,null=True)
    role = models.TextField(blank=True)
    location = models.TextField(blank=True)
    photo = models.ImageField(upload_to='users/%Y/%m/%d', blank=True)

    def __str__(self):
        return f'Profile for user {self.user.username}'

class Client(models.Model):
    firstname = models.CharField(blank=True, max_length=30)

    def __str__(self):
        return f'{self.firstname}'

我跑 python manage.py makemigrations 及 python manage.py migrate 代码运行良好，我还确保删除所有以前的迁移，因此我在迁移中成功创建了0001_initial.py文件。
我决定将我的新模型包含在admin.py文件中，这样我就可以从django的用户界面与模型交互

from django.contrib import admin
from .models import Profile, Client

@admin.register(Profile)
class ProfileAdmin(admin.ModelAdmin):
    list_display = ['user', 'photo','role']

@admin.register(Client)
class Client(admin.ModelAdmin):
    list_display = ['firstname']
    #list_display = ['firstname', 'lastname','position','country','email','phone']

这就是问题开始的地方，我可以成功地看到客户端模型是在管理部分创建的，但是当我点击模型时，我得到了这个错误 django.db.utils.OperationalError: no such table: account_client ```

stacktrace说明了这一切，似乎你的应用程序找不到表 account_client . 迁移时一定出了什么问题。如果可能的话，从一个新的db开始，或者至少删除所有表。然后删除所有迁移文件并重新执行迁移 makemigrations 指挥部。在那之后，你就可以走了！祝你好运

试着跑

python manage.py migrate --run-syncdb

运行正常迁移

python manage.py makemigrations <your-app-name>
python manage.py migrate <your-app-name>

如果不起作用，请尝试将其添加到每个模型：

class Meta:
        app_label = '<your-app-name>'

运行正常迁移

python manage.py makemigrations <your-app-name>
python manage.py migrate <your-app-name>

如果仍然存在，则：

python manage.py makemigrations <your-app-name>
python manage.py migrate <your-app-name> --fake

如果所有选项都不起作用，则有两个选项：
选择1
手动检查数据库中是否存在表
如果表不存在，请在数据库中手动创建该表。
选择2
如果它的调试数据库没有重要信息，请删除它，删除迁移并再次运行迁移。
