如何为给定Json创建模态类

# 导入Django的模型类
from django.db import models

# 创建模型类
class MyModel(models.Model):
    # 定义属性，与Json中的字段对应
    field1 = models.CharField(max_length=100)
    field2 = models.IntegerField()
    field3 = models.BooleanField()
    # ...

    # 添加必要的数据类型和验证规则

    # 添加嵌套类来表示Json中的嵌套对象
    class NestedModel(models.Model):
        nested_field1 = models.CharField(max_length=100)
        nested_field2 = models.IntegerField()
        # ...

    nested_object = models.OneToOneField(NestedModel, on_delete=models.CASCADE)

# 使用Django的Json解析库将Json数据转换为模型类的实例
json_data = '{"field1": "value1", "field2": 123, "field3": true, "nested_object": {"nested_field1": "nested_value1", "nested_field2": 456}}'
my_model_instance = MyModel.from_json(json_data)

# 访问模型类的属性
print(my_model_instance.field1)
print(my_model_instance.nested_object.nested_field1)
