医生在下面说DateField.auto_now_add https://docs.djangoproject.com/en/4.2/ref/models/fields/#django.db.models.DateField.auto_now_add。 *我用姜戈4.2.1:
首次创建对象时自动将该字段设置为现在。 ...如果您希望能够修改此字段，请设置以下内容而不是auto_now_add=True:
- For
DateField: default=date.today - from datetime.date.today()
- For
DateTimeField: default=timezone.now - from django.utils.timezone.now()
所以，我设置时区.now https://docs.djangoproject.com/en/4.2/ref/utils/#django.utils.timezone.now and 日期.今天 https://docs.python.org/3/library/datetime.html#datetime.date.today to datetime's 日期时间字段() https://docs.djangoproject.com/en/4.2/ref/models/fields/#datetimefield and date1's 日期字段() https://docs.djangoproject.com/en/4.2/ref/models/fields/#datefield分别，我也设置current_date返回timezone.now().date() and current_time返回timezone.now().time() to date2's DateField() and time's 时间字段() https://docs.djangoproject.com/en/4.2/ref/models/fields/#timefield分别如下图：
# "models.py"
from django.db import models
from datetime import date
from django.utils import timezone
def current_date():
return timezone.now().date()
def current_time():
return timezone.now().time()
class MyModel(models.Model):
datetime = models.DateTimeField(default=timezone.now) # Here
date1 = models.DateField(default=date.today) # Here
date2 = models.DateField(default=current_date) # Here
time = models.TimeField(default=current_time) # Here
然后，我设置'America/New_York' to 时区 https://docs.djangoproject.com/en/4.2/ref/settings/#std-setting-TIME_ZONE in settings.py如下所示：
# "settings.py"
LANGUAGE_CODE = "en-us"
TIME_ZONE = 'America/New_York' # Here
USE_I18N = True
USE_L10N = True
USE_TZ = True
But, date1's DateField() and time's TimeField()在 Django Admin 上分别显示 UTC（+0 小时）的日期和时间，如下所示：
接下来我设置'Asia/Tokyo' to TIME_ZONE in settings.py如下所示：
# "settings.py"
LANGUAGE_CODE = "en-us"
TIME_ZONE = 'Asia/Tokyo' # Here
USE_I18N = True
USE_L10N = True
USE_TZ = True
But, date2's DateField() and time's TimeField()在 Django Admin 上显示 UTC（+0 小时）的日期和时间，如下所示：
那么，如何设置当前正确的日期和时间DateField() and TimeField()分别作为默认值TIME_ZONE在 Django 模型中？
此外，DateField() and TimeField() with auto_now https://docs.djangoproject.com/en/4.2/ref/models/fields/#django.db.models.DateField.auto_now or 自动现在添加 https://docs.djangoproject.com/en/4.2/ref/models/fields/#django.db.models.DateField.auto_now_add无法分别保存 UTC（+0 小时）的日期和时间TIME_ZONE设置。
