如何在django管理中创建额外的选项

from django.db import models

class ExtraOptionField(models.Field):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        # 添加自定义的属性和验证规则

    def deconstruct(self):
        name, path, args, kwargs = super().deconstruct()
        # 添加自定义字段的反序列化逻辑
        return name, path, args, kwargs

from django.db import models

class MyModel(models.Model):
    extra_option = ExtraOptionField()
    # 其他字段和方法

python manage.py makemigrations
python manage.py migrate

from django.contrib import admin

class MyModelAdmin(admin.ModelAdmin):
    list_display = ('id', 'extra_option', ...)  # 在列表中显示的字段
    fields = ('extra_option', ...)  # 在编辑页面显示的字段

admin.site.register(MyModel, MyModelAdmin)
