Django：更新具有`django_mysql.models.jsonfield`的旧迁移文件？

在Django的较旧版本中，您可以通过django_mysql.models.jsonfield在模型中使用JSON字段。在Django的新版本中，JSONFIELD不再在django_mysql.models中。型号。

# Generated by Django 2.1.7 on 2019-07-17 22:59

from django.db import migrations
import django_mysql.models


class Migration(migrations.Migration):

    dependencies = [
        ('rss', '0009_delete_patternmatchingkeywords'),
    ]

    operations = [
        migrations.AddField(
            model_name='rssoutput',
            name='industries',
            field=django_mysql.models.JSONField(default=list), ##<== ERROR
        ),
    ]

我已经相应地更新了我的

attributeError：模块'django_mysql.models'没有属性'jsonfield'

解决此问题的正确过程是什么？

我正在使用：

Django 4.0
Python 3.9.13
Django-Mysql 4.7.0

In older versions of Django, you could use JSON fields in models via django_mysql.models.JSONField. In new versions of Django, JSONField is no longer in django_mysql.models. I've updated my models.py files accordingly, but I still have old migrations files that look like this:

# Generated by Django 2.1.7 on 2019-07-17 22:59

from django.db import migrations
import django_mysql.models


class Migration(migrations.Migration):

    dependencies = [
        ('rss', '0009_delete_patternmatchingkeywords'),
    ]

    operations = [
        migrations.AddField(
            model_name='rssoutput',
            name='industries',
            field=django_mysql.models.JSONField(default=list), ##<== ERROR
        ),
    ]

Now when I run makeMigration, I get this error:

AttributeError: module 'django_mysql.models' has no attribute 'JSONField'

What is the correct procedure to address this?

I'm using:

Django 4.0
Python 3.9.13
django-mysql 4.7.0

只需将其更改为Django建议的适当jsonfield：

from django.db.models import JSONField

...

class Migration(migrations.Migration):
    ...    
    operations = [
        migrations.AddField(
            ...
            field=JSONField(default=list)
        ),
    ]

Simply change it to proper JSONField that Django suggests:

from django.db.models import JSONField

...

class Migration(migrations.Migration):
    ...    
    operations = [
        migrations.AddField(
            ...
            field=JSONField(default=list)
        ),
    ]
