如何将Django Admin中的DateTimeField格式化为localtime？

Question

如何根据本地时间和时区格式化Admin中的DateTimeField？

我的settings.py:

    TIME_ZONE = 'Europe/Bratislava'
    LANGUAGE_CODE = 'en-us'
    USE_I18N = True
    USE_L10N = True
    USE_TZ = True

pytz包已安装.

模型:

class Material(models.Model):
    category = models.ForeignKey(Category, null=True, blank=True) 
    code = models.CharField(max_length=10)
    description = models.CharField(max_length=30, blank=True, null=True)
    modified = models.DateTimeField(auto_now=True)
    created = models.DateTimeField(auto_now_add=True)

还在设置中尝试了一些日期格式化,这没有改变datetime对象在管理列表显示中转换为字符串的方式:

DATETIME_FORMAT = 'd N Y'
DATE_FORMAT = 'd N Y'

在数据库中,datetime正确存储,"2012-11-20 08:57:15.901341 + 01".但是在admin中显示时,它始终是UTC.

我可以在ModelAdmin中准备处理格式的方法,但这并不是真的干,因为我想我的管理类看起来像:

from django.utils.timezone import localtime

class MaterialAdmin(admin.ModelAdmin):
    list_display = ('code', 'modified_local', 'created')

    def modified_local(self, row):
        return localtime(row.modified)
    modified_local.admin_order_field = 'modified'
    modified_local.short_description = 'Modified'

这个问题的答案,你的问题是正确的配置settings,并formats在Django项目.示例项目的结构:

.
|-- README.md
|-- demo.db
|-- demo_time_set
|   |-- __init__.py
|   |-- demo.db
|   |-- formats
|   |   |-- __init__.py
|   |   `-- en
|   |       |-- __init__.py
|   |       `-- formats.py
|   |-- settings.py
|   |-- urls.py
|   `-- wsgi.py
|-- manage.py
|-- requirments.txt
`-- some_app
    |-- __init__.py
    |-- admin.py
    `-- models.py

您可以通过提供具有适当名称和formats.py的目录来为多种语言定义它.formats.py所有MAGIC发生的示例内容可以如下所示:

# HERE FORMATING AS shown in:
# LIST: https://docs.djangoproject.com/en/dev/ref/templates/builtins/#date
DATE_FORMAT = 'd-m-Y'
TIME_FORMAT = 'H:i'
DATETIME_FORMAT = 'd-m-Y H:i'
YEAR_MONTH_FORMAT = 'F Y'
MONTH_DAY_FORMAT = 'F j'
SHORT_DATE_FORMAT = 'm/d/Y'
SHORT_DATETIME_FORMAT = 'm/d/Y P'
FIRST_DAY_OF_WEEK = 1

# BUT here use the Python strftime format syntax,
# LIST: http://docs.python.org/library/datetime.html#strftime-strptime-behavior

DATE_INPUT_FORMATS = (
    '%d-%m-%Y',     # '21-03-2014'
)
TIME_INPUT_FORMATS = (
    '%H:%M:%S',     # '17:59:59'
    '%H:%M',        # '17:59'
)
DATETIME_INPUT_FORMATS = (
    '%d-%m-%Y %H:%M',     # '21-03-2014 17:59'
)

DECIMAL_SEPARATOR = u'.'
THOUSAND_SEPARATOR = u','
NUMBER_GROUPING = 3

请注意评论中的两个链接,它们将指导您正确配置的列表,这些配置对于不同的部件是不同的!

在你settings.py刚才添加:

FORMAT_MODULE_PATH = 'demo_time_set.formats'
