升级后Django-Picklefield变化结构

发布于 2025-02-11 21:19:16 字数 875 浏览 0 评论 0原文

我将Django应用程序从1.11.16迁移到4.0.5，而Django-Picklefield也将从2.0迁移到3.1。

Django对象具有以下行：

from picklefield.fields import PickledObjectField

class A(models.Model):
    ...
    log_list = PickledObjectField(default=list)

。

使用旧代码（1.11.16）和新代码（4.0.5）结果的查询结果完全不同：

#old
Obj.objects.get(id=4737).log_list
[{u'date': datetime.datetime(2022, 6, 27, 12, 54, 50, 746392),
u'message': u'Fetching trademark search started',
u'typ': u'info'},
{u'date': datetime.datetime(2022, 6, 27, 12, 54, 53, 423384),
u'message': u'Fetching trademark search finished',
u'typ': u'info'}]
#type == list

#new
Obj.objects.get(id=4737).log_list
gAJdcQEofXECKFgEAAAAZGF0ZXEDY2RhdGV0aW1lCmRhdGV0aW1....
#so it results exactly what is stored in the db.
#type == str

使用Picklefield版本3.1，我需要做 /更改其他任何事情以比使用版本== 2.0？我该如何处理新设置以获取列表而不是STR？

I'm migrating a Django app from 1.11.16 to 4.0.5 and django-picklefield will be migrated also from 2.0 to 3.1 .

A django object has the following line:

from picklefield.fields import PickledObjectField

class A(models.Model):
    ...
    log_list = PickledObjectField(default=list)

Using the old code (1.11.16) and the new code (4.0.5) results a totally different result for the query:

#old
Obj.objects.get(id=4737).log_list
[{u'date': datetime.datetime(2022, 6, 27, 12, 54, 50, 746392),
u'message': u'Fetching trademark search started',
u'typ': u'info'},
{u'date': datetime.datetime(2022, 6, 27, 12, 54, 53, 423384),
u'message': u'Fetching trademark search finished',
u'typ': u'info'}]
#type == list

#new
Obj.objects.get(id=4737).log_list
gAJdcQEofXECKFgEAAAAZGF0ZXEDY2RhdGV0aW1lCmRhdGV0aW1....
#so it results exactly what is stored in the db.
#type == str

With picklefield version 3.1 is there anything else I need to do / change to have the behaviour than with version == 2.0 ?
What should I do with the new setup to get the list instead of the str?
