Question

我想写一个基于类的视图，我想清理一部分URL：

网址如下所示：

r'^some-date/(?P<date>\d\d\d\d-\d\d-\d\d)/view'

我应该使用哪种方法将字符串（例如“2018-12-31”）“清理”到python datetime对象？

Answer 1

在django2.0中我们可以使用路径转换器。

custom_path_converter.py

from datetime import datetime

class DatePathConverter:
    regex = '\d\d\d\d-\d\d-\d\d'

    def to_python(self, date_str):
        date = datetime.strptime(value, "%Y-%m-%d").date()
        return date

    def to_url(self, date):
        return date.strftime("%Y-%m-%d")

urls.py

from django.urls import register_converter, path
from .views import views
register_converter(DatePathConverter, 'date')

urlpatterns = [
    # ....
    path('some-date/<date:date>/', views.some_view)
    # ....
]

Answer 2

def clean_date(request, date):
    datetime_object = datetime.strptime(date, '%b %d %Y %I:%M%p')
