在 Wagtail 博客中找不到标签：使用 mysite.urls 中定义的 URLconf，Django 尝试了这些 URL 模式

Question

我正在关注 Wagtail v2.4 tutorial 并向博客添加了标记功能。但是，当我单击博客 post 上的标签 link 时，出现 404 错误。标签索引页面 (/tags/) 显示所有 post 没有任何标签。我只创建了一个带标签的 post。

Page not found (404)

Request Method: GET

Request URL: http://localhost:8000/tags/tag%3Dnewswithimages

Using the URLconf defined in koamrn.urls, Django tried these URL patterns, in this order:

^django-admin/

^admin/

^documents/

^search/$ [name='search']

^_util/authenticate_with_password/(\d+)/(\d+)/$[name='wagtailcore_authenticate_with_password']

^_util/login/$ [name='wagtailcore_login']

^((?:[\w-]+/)*)$ [name='wagtail_serve']

^static/(?P.*)$

^media/(?P.*)$

The current path, tags/tag=newswithimages, didn't match any of these.

我想我需要在 urls.py?

中添加路径

from django.conf import settings
from django.conf.urls import include, url
from django.contrib import admin

from wagtail.admin import urls as wagtailadmin_urls
from wagtail.core import urls as wagtail_urls
from wagtail.documents import urls as wagtaildocs_urls

from search import views as search_views

urlpatterns = [
    url(r'^django-admin/', admin.site.urls),

    url(r'^admin/', include(wagtailadmin_urls)),
    url(r'^documents/', include(wagtaildocs_urls)),

    url(r'^search/$', search_views.search, name='search'),

    # For anything not caught by a more specific rule above, hand over to
    # Wagtail's page serving mechanism. This should be the last pattern in
    # the list:
    url(r'', include(wagtail_urls)),

    # Alternatively, if you want Wagtail pages to be served from a subpath
    # of your site, rather than the site root:
    #    url(r'^pages/', include(wagtail_urls)),
]


if settings.DEBUG:
from django.conf.urls.static import static
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

# Serve static and media files from development server
urlpatterns += staticfiles_urlpatterns()
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

news_tag_index_page.html:

{% extends "base.html" %}
{% load wagtailcore_tags %}

{% block content %}
    {% if request.GET.tag|length %}
        <h4>Showing pages tagged "{{ request.GET.tag }}"</h4>
    {% endif %}

    {% for newspage in newspages %}

        <p>
            <strong><a href="{% pageurl newspage %}">{{ newspage.title }}</a></strong><br />
            <small>Revised: {{ newspage.latest_revision_created_at }}</small><br />
            {% if newspage.author %}
                <p>By {{ newspage.author.profile }}</p>
            {% endif %}
        </p>

    {% empty %}
        No pages found with that tag.
    {% endfor %}
{% endblock %}

Answer 1

您只需要继续阅读教程:)

"Visiting a blog post with tags should now show a set of linked buttons at the bottom - one for each tag. However, clicking a button will get you a 404, since we haven’t yet defined a “tags” view."

https://docs.wagtail.io/en/v2.4/getting_started/tutorial.html#tagging-posts

Answer 2

标签列表页面的 URL 应该是 /tags?tag=newswithimages，而不是 tags/tag=newswithimages。很可能，您在 blog_page.html 上的 link 中打错了字：

<a href="{% slugurl 'tags' %}?tag={{ tag }}"><button type="button">{{ tag }}</button></a>
