本文将介绍在网址格式中使用include的详细情况，特别是关于时出现意外的NoReverseMatch错误的相关信息。我们将通过案例分析、数据研究等多种方式，帮助您更全面地了解这个主题，同时也将涉及一些关于could not parse as expression: "/login" (template: "include/include" - line 3...、Django - NoReverseMatch 位于 /project/3/evillio、Django NoReverseMatch 错误关键字参数 '{'slug': ''}' 上的 Django 错误未找到、Django 博客 url 错误 NoReverseMatch at /的知识。

引用时，我得到一个错误detail.html的index.html

Reverse for ''detail'' with arguments ''(3,)'' and keyword arguments ''{}'' notfound. 1 pattern(s) tried: [''$(?P<pk>[0-9]+)/$'']

views.py

def rock_and_feat(request):    feats = Feat.objects.order_by(''-created'')[:3]    rocks = Rockinfo.objects.order_by(''-rank'')[:50]    context = RequestContext(request, {        ''feats'': feats, ''rocks'': rocks    })    return render_to_response(''template.html'', context)class DetailView(generic.DetailView):    model = Feat    template_name = ''feature/detail.html''     context_object_name = ''feat''

urls.py

urlpatterns = [    url(r''^$'', views.rock_and_feat, name=''rock_and_feat''),    url(r''^(?P<pk>[0-9]+)/$'', views.DetailView.as_view(), name=''detail''),]

index.html

{% extends "index.html" %}{% block mainmast %}<div id="wrapper">{% if feats %}{% for feat in feats %} <div> <a href="{% url ''feature:detail'' feat.id %}"><img src="{{ feat.image.url }}" alt="some text"></a>  <h1>    <a href="#">{{feat.title}}</a>  </h1> </div> {% endfor %} {% else %}<p>No </p> {% endif %}</div>{% endblock %}

detail.html

{% extends "index.html" %}<iframe width="560" height="345" src="{{ feat.youtube_link }}"       frameborder="0" allowfullscreen></iframe>

项目urls.py

from django.conf.urls import include, urlfrom django.contrib import adminfrom django.conf import settingsfrom django.conf.urls.static import staticurlpatterns = [    url(r''^$'', include(''feature.urls'', namespace="feature")),    url(r''^admin/'', include(admin.site.urls)),] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

在将<a href= 中的图片添加到之前，该应用程序运行良好index.html。

无法找出问题所在。

答案1

小编典典

这表明存在问题。

''$(?P<pk>[0-9]+)/$''

模式的开头不应有美元符号（与字符串的末尾匹配）。

该问题是由您包含urls.py的方式引起的。您目前在正则表达式中有一个美元：

url(r''^$'', include(''feature.urls'', namespace="feature")),

要解决此问题，请从正则表达式中删除美元。

url(r''^'', include(''feature.urls'', namespace="feature")),

could not parse as expression:

could not parse as expression: "/login" (template: "include/include" - line 3...

<li><a href="login.html" th:href="/login">登录</a></li>

Django - NoReverseMatch 位于 /project/3/evillio

您收到的错误是因为 project-detail.html 底部的这一行：

<a href="{% url 'project-detail' next.pk next.slug %}"data-dsn-ajax="next-project">

如果没有 next (context["next"])，则 django 无法找出 url，并且您会看到您看到的错误。

用 {% if next %} 将链接到“next”的最后一段包裹起来：

{% if next %}
<divdata-dsn-footer="project">
    <div id="dsn-next-parallax-img">
        <divdata-overlay="2"
            data-image-src="{{ next.featured_image.url }}"></div>
    </div>
    <div id="dsn-next-parallax-title">
        <a href="{% url 'project-detail' next.pk next.slug %}"data-dsn-ajax="next-project">
            <div>
                <div>
                    <span>{{ next.title }}</span>

我似乎无法理解发生了什么。

解决方法

更新这一行，将解决所有问题：

  path(''notes/'',include(''notebooks.urls'',namespace=''notebooks'')),

在您项目的 url.py 中，您应该在路径上指定 namespace 以匹配您的笔记本 app_name...

url.py

此外，在你有 path(''notes/'', 的地方，它应该是 <a href="{% url ''notebooks:note-detail'' slug=note.slug %}">，因为它在循环内循环遍历 object_list。同样为了将来参考以使其更容易一些，您可以在模型对象上使用 get_absolute_url 。让您免于头痛。

您可以使用例如：

<a href="{% url ''notebooks:note-detail'' slug=item.slug %}">

仍然等价于：

<a href="{{ item.get_absolute_url }}">...</a>

这样既能完成工作，也更清晰易读。
