有没有办法让django管理人员自定义模型模式

from django.db import models

def create_dynamic_model(model_name, fields):
    attrs = {}
    for field_name, field_type in fields.items():
        attrs[field_name] = models.CharField(max_length=100)

    Meta = type('Meta', (), {'db_table': model_name})
    attrs['Meta'] = Meta

    dynamic_model = type(model_name, (models.Model,), attrs)
    return dynamic_model

# 创建一个动态模型
fields = {'name': models.CharField(max_length=100), 'age': models.IntegerField()}
DynamicModel = create_dynamic_model('Person', fields)

# 使用动态模型
person = DynamicModel(name='John', age=25)
person.save()
