Question

我在django 2.1应用程序上进行迁移时遇到错误

from django.db import migrations, models
import django.db.models.deletion


class Migration(migrations.Migration):

    dependencies = [
        ('sawy', '0005_auto_20190418_0607'),
    ]

    operations = [
        migrations.AlterField(
            model_name='response',
            name='action',
            field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, related_name='response', to='sawy.Action'),
        ),
    ]

错误：

 Applying sawy.0006_auto_20190418_0608...Traceback

class Response(models.Model):
    action = models.ForeignKey(Action, on_delete=models.CASCADE, related_name='response')
    text = models.TextField(blank=True,unique=True)
    def __str__(self):
        return self.text

Django 2.1已经放弃了对postgres 9.3的支持

尝试更新你的postgres版本

django 2.1发布note
