在 urls.py 中未检测到 Django DayArchiveview

Question

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按预期运行，但未检测到显示日期的视图。例如，如果我尝试获取http://127.0.0.1:8000/blog/archive/2021/ 或http://127.0.0.1:8000/blog/archive/2021/01 将显示视图，http://127.0.0.1:8000/blog/archive/2021/01/07 将失败。我知道问题必须与 urls.py 配置有关，但我只是在文档中找不到它。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>

错误

Answer 1

您的 URL 模式匹配正确，具体而言，'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 的月份字段是一个缩写月份name。因此，根据urls.py 中您的 URL 模式上方的评论，您的 URL 应该是 http://127.0.0.1:8000/blog/archive/2021/jan/07。

更新

您可以通过在您的PostDayArchiveView 中设置month_format 将预期月份格式更改为用零填充的月份数。

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。

Answer 2

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 而不是这种方式 -> http://127.0.0.1:8000/blog/archive/2021/01/07。这将是一种更简单的方式来处理您想要的事情

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'),
]
