我在Django中创建了几个基于日期的视图，虽然年份和月份的视图与预期的一样，但显示天数的视图没有被检测到。例如，如果我试图获得http://127.0.0.1:8000/blog/archive/2021/，或者http://127.0.0.1:8000/blog/archive/2021/01视图将被显示，http://127.0.0.1:8000/blog/archive/2021/01/07将失败。我理解urls.py配置的问题，但我在文档中找不到它。我还尝试将day_format=‘’%d‘传递给as_view方法，但没有任何结果。

urls.py

from django.urls import path, re_path

from blog import views

app_name = 'blog'

urlpatterns = [
    # Example: /blog/
    path('', views.PostListView.as_view(), name='index'),

    # Example: /blog/post/ (same as /blog/)
    path('post/', views.PostListView.as_view(), name='post_list'),

    # Example: /blog/post/django-example/
    re_path(r'^post/(?P<slug>[-\w]+)/$', views.PostDetailView.as_view(), name='post_detail'),

    # Example: /blog/archive/
    path('archive/', views.PostArchiveView.as_view(), name='post_archive'),

    # Example: /blog/archive/2019/
    path('archive/<int:year>/', views.PostYearArchiveView.as_view(), name='post_year_archive'),

    # Example: /blog/archive/2019/nov/
    path('archive/<int:year>/<int:month>/', views.PostMonthArchiveView.as_view(month_format='%m'), name='post_month_archive'),

    # Example: /blog/archive/2019/nov/10/
    path('archive/<int:year>/<str:month>/<int:day>/', views.PostDayArchiveView.as_view(), name='post_day_archive'),

    # Example: /blog/archive/today/
    path('archive/today/', views.PostTodayArchiveView.as_view(), name='post_today_archive'),
]

views.py

from django.shortcuts import render

# Create your views here.
from django.views.generic import ListView, DetailView, ArchiveIndexView, YearArchiveView, MonthArchiveView, \
    DayArchiveView, TodayArchiveView

from blog.models import Post


class PostListView(ListView):
    model = Post
    template_name = 'blog/post_all.html'
    context_object_name = 'posts'
    paginate_by = 2


class PostDetailView(DetailView):
    model = Post


class PostArchiveView(ArchiveIndexView):
    model = Post
    date_field = 'modify_dt'


class PostYearArchiveView(YearArchiveView):
    model = Post
    date_field = 'modify_dt'
    make_object_list = True


class PostMonthArchiveView(MonthArchiveView):
    model = Post
    date_field = 'modify_dt'


class PostDayArchiveView(DayArchiveView):
    model = Post
    date_field = 'modify_dt'


class PostTodayArchiveView(TodayArchiveView):
    model = Post
    date_field = 'modify_dt'

post_archive_day.html

<h1>Post Archives for {{ day|date:"N d, Y" }}</h1>

<div>
    <ul>
        {% for post in object_list %}
        <li>
            {{ post.modify_dt|date:"Y-m-d" }}&nbsp;&nbsp;&nbsp;
            <a href="{{ post.get_absolute_url }}"><strong>{{ post.title }}</strong></a>
        </li>
        {% endfor %}
    </ul>
</div>

您的URL模式是正确匹配的，特别是'archive/<int:year>/<str:month>/<int:day>/'将与URL http://127.0.0.1:8000/blog/archive/2021/01/07匹配。

错误消息指示无效的日期字符串。它期望指定为%b的月份字段是缩写的月份名称。因此，您的URL应该是http://127.0.0.1:8000/blog/archive/2021/jan/07，按照urls.py中您的URL模式上面的注释。

更新

通过在month_format中设置PostDayArchiveView，您可以将预期的月份格式更改为零填充月份号。

class PostDayArchiveView(DayArchiveView):
    model = Post
    date_field = 'modify_dt'
    month_format = '%m'

现在，您可以使用URL模式'archive/<int:year>/<int:month>/<int:day>/'来接受所需的URL格式。

您可以尝试以这种方式获取日期->http://127.0.0.1:8000/blog/archive/2021-01-07而不是-> http://127.0.0.1:8000/blog/archive/2021/01/07。这将是一种处理你想要的事情的更简单的方法。

from django.urls import path, register_converter
from datetime import datetime
from . import views

class DateConverter:
    regex = '\d{4}-\d{2}-\d{2}'

    def to_python(self, value):
        return datetime.strptime(value, '%Y-%m-%d')

    def to_url(self, value):
       return value

register_converter(DateConverter, 'yyyy')

urlpatterns = [
    path('', views.index, name='index'),
    path('date/<yyyy:date>/', views.date, name='date'),
]
