如何使用app_name = 'scrumboard'
将django urlpatterns与DRF路由器结合在一起?我尝试了DRF documentation解释过的所有方法,但仍然无法解决这个问题。到目前为止,我有以下urls.py文件:
#scrumboard/urls.py
from rest_framework.routers import DefaultRouter
from .api import ListViewSet, CardViewSet
from django.urls import re_path, path, include
from . import views
router = DefaultRouter()
router.register(r'lists', ListViewSet)
router.register(r'cards', CardViewSet)
app_name = 'scrumboard'
urlpatterns = [
path('', views.index, name="index"),
re_path(r'^api/', include((router.urls))),
]
这是我的项目urls.py:
#project/urls.py
from django.contrib import admin
from django.urls import include, path, re_path
#Add URL maps to redirect the test URL to our application
from django.views.generic import RedirectView
# Use static() to add url mapping to serve static files during development (only)
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('', include('home.urls')),
path('admin/', admin.site.urls),
path('accounts/', include('django.contrib.auth.urls')),
path('test/', RedirectView.as_view(url='/catalog/', permanent=True)),
path('polls/', include('polls.urls')),
path('blog/', include('blog.urls')),
path('catalog/', include('catalog.urls')),
path('scrumboard/', include('scrumboard.urls'))
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
在我的模板中,我将有机会定义动态网址,如下所示:
<li><a href="{% url 'scrumboard:index' %}">Scrumboard</a></li>
将把我带到我的Scrumboard应用程序。

我们如何期望/scrumboard/
匹配第一个正则表达式?是否有一个外部urls.py
文件,其中包含您提到的文件?
如果没有更多信息,这是否有效?
urlpatterns = [
path('^scrumboard/?$', views.index, name="index"),
re_path(r'^api/', include((router.urls))),
]

我只是想删除这个问题,但我想也许其他人会反对这一点并决定描述问题究竟是什么。
由于经验不足,我在错误的地方寻找问题。
按照主页模板上的链接:
<li><a href="{% url 'scrumboard:index' %}">Scrumboard</a></li>
#scrumboard/urls.py
from django.urls import re_path, path, include
from . import views
app_name = 'scrumboard'
urlpatterns = [
path('', views.index, name="index"),
]
我们运行了一个在view.py中定义的函数,该函数接受此请求并在scrumboard/index.html
下呈现模板
#scrumboard/views.py
def index(request):
return render(request, 'scrumboard/index.html', {})
这里有错误。
Exception Type: NoReverseMatch at /scrumboard/
Exception Value: Reverse for 'lists' not found. 'lists' is not a valid view function or pattern name.
我使用了django Reversing namespaced URLs,因为我有几个应用程序,每个应用程序都有自己的index.html模板。我不得不猜测问题出在这个模板的某个地方:
{% extends 'base.html' %}
{% load static %}
{% block title %}
<title>Scrumboard</title>
{% endblock %}
{% block extracss %}
<link rel="stylesheet" href="{% static 'scrumboard/css/main.css' %}" />
{% endblock %}
{% block content %}
<a href="{% url 'scrumboard:lists' %}" target="_blank" class="top-menu">Lists</a><br>
<a href="{% url 'scrumboard:cards' %}" target="_blank" class="top-menu">Cards</a>
<hr>
<div ng-app="scrumboard.demo">
{% verbatim %}
<div ng-controller="ScrumboardController">
<div ng-repeat="list in data">
<h3>{{list.name}}</h3>
<ul>
<li ng-repeat="card in list.cards">{{card.title}}</li>
</ul>
<div class="input-group">
<input type="text" ng-model="new_title">
<button class="btn btn-outline-secondary" ng-click="add(list, new_title)">+</button>
</div>
</div>
</div>
{% endverbatim %}
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<script type="text/javascript" src="{% static 'scrumboard/js/scrumboard.js' %}"></script>
</div>
{% endblock %}
看到这些界限,我认为问题可能在于:
<a href="{% url 'scrumboard:lists' %}" target="_blank" class="top-menu">Lists</a><br>
<a href="{% url 'scrumboard:cards' %}" target="_blank" class="top-menu">Cards</a>
我决定只评论他们。在认为问题已经解决之后,我重新加载了页面,但错误仍然会再次出现。
<!-- <a href="{% url 'scrumboard:lists' %}" target="_blank" class="top-menu">Lists</a><br>
<a href="{% url 'scrumboard:cards' %}" target="_blank" class="top-menu">Cards</a> -->
但是django忽略了通常的html注释并尝试阅读注释代码。所以我的错误没有消失,我开始在其他地方寻找问题。 由于缺乏经验,我问了一个不正确的问题。 只需删除此行即可解决我的问题。
