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 模式答案

【问题描述】：

我正在关注Wagtail v2.4 tutorial 并向博客添加了标记功能。但是，当我单击博客文章上的标签链接时，我收到 404 错误。标签索引页面 (/tags/) 显示所有没有任何标签的帖子。我只创建了一个带有标签的帖子。

找不到页面 (404)

请求方法：GET

请求网址：http://localhost:8000/tags/tag%3Dnewswithimages

使用 koamrn.urls 中定义的 URLconf，Django 按以下顺序尝试了这些 URL 模式：

^django-admin/

^admin/

^文档/

^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.*)$

当前路径 tags/tag=newswithimages 与其中任何一个都不匹配。

我猜我需要在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 %}

【问题讨论】：

标签： wagtail

【解决方案1】：

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 的链接中打错了：

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

【讨论】：

是的！我错过了tag={{ tag }} 之前的问号。谢谢@gasman！

【解决方案2】：

你只需要继续阅读教程:)

“访问带有标签的博客文章现在应该在底部显示一组链接按钮 - 每个标签都有一个按钮。但是，单击按钮会得到 404，因为我们尚未定义“标签”视图。”
