Django 2.0.7 - 执行重命名字段迁移时的语法错误

Question

我有以下Django类：

class Contacto(models.Model):
responsable_documento = models.CharField(primary_key=True, max_length=40)
responsable_tipo_documento = models.CharField(max_length=20)
responsable_nombre = models.CharField(max_length=50, blank=True)
responsable_apellido = models.CharField(max_length=60, blank=True)
responsable_telefono = models.CharField(max_length=20, blank=True)
responsable_telefono_particular = models.CharField(max_length=20, blank=True)
responable_email_uno = models.EmailField()
responsable_email_dos = models.EmailField()
responsable_email_tres = models.EmailField()
cueanexo = models.PositiveIntegerField(null=True)
class Meta:
unique_together = (
('responsable_documento', 'responsable_tipo_documento', 'alumno_documento', 'alumno_tipo_documento'),
)
verbose_name_plural = 'contactos'

我正在尝试重命名一些字段：

class Contacto(models.Model):
responsable_documento = models.CharField(primary_key=True, max_length=40)
responsable_tipo_documento = models.CharField(max_length=20)
responsable_nombre = models.CharField(max_length=50, blank=True)
responsable_apellido = models.CharField(max_length=60, blank=True)
responsable_telefono = models.CharField(max_length=20, blank=True)
responsable_telefono_celular = models.CharField(max_length=20, blank=True)
responable_email1 = models.EmailField()
responsable_email2 = models.EmailField()
responsable_email3 = models.EmailField()
cue_anexo = models.PositiveIntegerField(null=True)
class Meta:
unique_together = (
('responsable_documento', 'responsable_tipo_documento', 'alumno_documento', 'alumno_tipo_documento'),
)
verbose_name_plural = 'contactos'

这将导致以下迁移：

class Migration(migrations.Migration):
dependencies = [
('datos_basicos', '0008_auto_20180813_1505'),
]
operations = [
migrations.RenameField(
model_name='contacto',
old_name='cueanexo',
new_name='cue_anexo',
),
migrations.RenameField(
model_name='contacto',
old_name='responable_email_uno',
new_name='responable_email1',
),
migrations.RenameField(
model_name='contacto',
old_name='responsable_email_dos',
new_name='responsable_email2',
),
migrations.RenameField(
model_name='contacto',
old_name='responsable_email_tres',
new_name='responsable_email3',
),
migrations.RenameField(
model_name='contacto',
old_name='responsable_telefono_particular',
new_name='responsable_telefono_celular',
),
]

当我尝试应用所述迁移时，会发生以下错误：

Running migrations:
Applying datos_basicos.0009_auto_20180813_1731...Traceback (most recent call last):
File "/home/desarrollo/.local/share/virtualenvs/censo_estudiantil-86GgnGcQ/lib/python3.5/site-packages/django/db/backends/utils.py", line 85, in _execute

psycopg2.ProgrammingError: syntax error at or near "WITH ORDINALITY"

有谁知道可能导致此错误的原因？

Answer 1

切换到Django 2.1 后我收到了相同的错误消息，更新我的 Postgres 版本为我修复了这个问题。但是在 2.1 版本中的支持有所下降 https://docs.djangoproject.com/en/2.1/releases/2.1/#dropped-support-for-postgresql-9-3

Answer 2

我认为这是一个django错误。 就我而言，降级到2.0版是有效的。最好的。何塞

Answer 3

该错误适用于大于 2.0 的 django 版本.将 django 版本降级到 2.0 和与 9.3 相同的 Postgres 版本对我有用。
