Django执行makemigrations时admin_db应用模型字段全部被忽略如何解决

问题根因

你编写的Admin模型中所有自定义字段，都使用了Python类型注解语法（冒号:声明），而Django ORM要求字段必须以类属性赋值的方式（等号=赋值）声明，迁移生成逻辑只会识别赋值类属性作为模型字段，类型注解不会被识别，这就是字段全部被忽略的原因。

修正后的模型代码

from django.db import models
from datetime import datetime


class Admin(models.Model):
    # 所有字段声明将冒号改为等号即可被Django识别
    Admin_Email = models.EmailField(primary_key=True, editable=False)
    First_name = models.CharField(max_length=25)
    Last_name = models.CharField(max_length=25)
    Gender = models.CharField(max_length=1)
    Date_of_registration = models.DateField(default=datetime.now, editable=False)
    Date_of_Birth = models.DateField()
    # 额外提示：BigIntegerField本身不支持max_length参数，如需限制长度建议改用CharField加数字正则校验
    CNIC = models.BigIntegerField(unique=True)
    City = models.CharField(max_length=50)
    Area = models.CharField(max_length=50)
    Address = models.CharField(max_length=100)
    # 同上，BigIntegerField无max_length参数
    Phone_num = models.BigIntegerField(unique=True)


class Salt(models.Model):
    Admin_email = models.OneToOneField(Admin, on_delete=models.CASCADE)
    Salt = models.CharField(max_length=25, unique=True)


class Password(models.Model):
    Admin_email = models.OneToOneField(Admin, on_delete=models.CASCADE)
    hash = models.CharField(max_length=255, unique=True)
