我想将我的字符串日期转换为 django 日期格式。我尝试了一个方法。但没有用。

我收到了这个错误。
time data '2014-04-07' does not match format 'Y-mm-dd'

It should be %Y-%m-%d
:
它应该是%Y-%m-%d
:
>>> s = "2014-04-07"
>>> datetime.datetime.strptime(s, "%Y-%m-%d").date()
datetime.date(2014, 4, 7)
According to the documentation:
根据文档:
%Y
stands for a year with century as a decimal number%m
- month as a zero-padded decimal number%d
- day of the month as a zero-padded decimal number
%Y
代表以世纪为十进制数的年份%m
- 月份作为零填充的十进制数%d
- 以零填充的十进制数表示的月份日期
Hope that helps.
希望有帮助。

django.utils.dateparse.parse_date
function will return None
if given date not in %Y-%m-%d
format
django.utils.dateparse.parse_date
None
如果给定的日期%Y-%m-%d
格式不正确,函数将返回
I have not found a function in django source code to parse string by DATE_INPUT_FORMATS
. So I wrote a custom helper function for that and
I have added to here for help others.
我还没有在 django 源代码中找到一个函数来解析字符串DATE_INPUT_FORMATS
。因此,我为此编写了一个自定义帮助器函数,并将其添加到此处以帮助其他人。
from datetime import datetime
from django.utils.formats import get_format
def parse_date(date_str):
"""Parse date from string by DATE_INPUT_FORMATS of current language"""
for item in get_format('DATE_INPUT_FORMATS'):
try:
return datetime.strptime(date_str, item).date()
except (ValueError, TypeError):
continue
return None
