“DATETIME_INPUT_FORMATS”在 Django Admin 中不起作用，而“DATE_INPUT_FORMATS”和“TIME_INPUT_FORMATS”则可以

I use 日期时间字段() https://docs.djangoproject.com/en/4.2/ref/models/fields/#datetimefield, 日期字段() https://docs.djangoproject.com/en/4.2/ref/models/fields/#datefield and 时间字段() https://docs.djangoproject.com/en/4.2/ref/models/fields/#timefield in MyModel类如下图所示。 *我用姜戈4.2.1:

# "models.py"

from django.db import models

class MyModel(models.Model):
    datetime = models.DateTimeField() # Here
    date = models.DateField() # Here
    time = models.TimeField() # Here

然后，我设置DATE_INPUT_FORMATS https://docs.djangoproject.com/en/4.2/ref/settings/#date-input-formats and TIME_INPUT_FORMATS https://docs.djangoproject.com/en/4.2/ref/settings/#time-input-formats并设置USE_L10N https://docs.djangoproject.com/en/4.2/ref/settings/#use-l10n False使DATE_INPUT_FORMATS and TIME_INPUT_FORMATS工作于settings.py如下所示：

# "settings.py"

LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = False # Here

USE_TZ = True

DATE_INPUT_FORMATS = ["%m/%d/%Y"] # '10/25/2023' # Here
TIME_INPUT_FORMATS = ["%H:%M"] # '14:30' # Here

Then, DATE_INPUT_FORMATS and TIME_INPUT_FORMATS在 Django Admin 中工作，如下所示：

接下来我设置DATETIME_INPUT_FORMATS https://docs.djangoproject.com/en/4.2/ref/settings/#std-setting-DATETIME_INPUT_FORMATS并设置USE_L10N False使DATETIME_INPUT_FORMATS工作于settings.py如下所示：

# "settings.py"

LANGUAGE_CODE = 'en-us'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_L10N = False # Here

USE_TZ = True

DATETIME_INPUT_FORMATS = ["%m/%d/%Y %H:%M"] # '10/25/2023 14:30'

But, DATETIME_INPUT_FORMATS在 Django Admin 中不起作用，如下所示：

此外，从一个MyModel对象，我得到并打印datetime, date and time并将它们传递给index.html in test() in views.py如下所示：

# "views.py"

from django.shortcuts import render
from .models import MyModel

def test(request):
    obj = MyModel.objects.all()[0]
    print(obj.datetime)
    print(obj.date)
    print(obj.time)
    return render(
        request, 
        'index.html', 
        {"datetime": obj.datetime, "date": obj.date, "time": obj.time}
    )

但是，所有DATE_INPUT_FORMATS, TIME_INPUT_FORMATS and DATETIME_INPUT_FORMATS根据控制台不起作用，如下所示：

2023-10-25 14:30:15+00:00
2023-10-25
14:30:15

接下来我展示datetime, date and time in index.html如下所示：

# "index.html"

{{ datetime }}<br/>
{{ date }}<br/>
{{ time }} 

但是，所有DATE_INPUT_FORMATS, TIME_INPUT_FORMATS and DATETIME_INPUT_FORMATS根据浏览器不起作用，如下所示：

Oct. 25, 2023, 2:30 p.m.
Oct. 25, 2023
2:30 p.m.

我的问题：

1. 我怎样才能使DATETIME_INPUT_FORMATS在 Django 管理中工作？
2. 为什么不DATETIME_INPUT_FORMATS在 Django 管理中工作？
3. If DATETIME_INPUT_FORMATS在 Django Admin 中不起作用，在哪里DATETIME_INPUT_FORMATS work?
