from .models import YourModel

class YourModelAdmin(admin.ModelAdmin):
    list_display = ('id', 'comma_field', 'sorted_field')

    def sorted_field(self, obj):
        # 将CommaSeparatedIntegerField转换为整数列表
        integer_list = [int(x) for x in obj.comma_field.split(',')]

        # 对整数列表进行排序
        sorted_list = sorted(integer_list)

        # 返回排序后的结果
        return ','.join(str(x) for x in sorted_list)

    sorted_field.admin_order_field = 'comma_field'  # 指定排序字段

admin.site.register(YourModel, YourModelAdmin)
