我只是不知道发生了什么

I just dont get what's happening

您可以在此处看到完整的代码:

You can see full code here:

github/AngelQuesada/videoclub_django

这是失败的部分(base_generic.html)

This is the part where it fails (base_generic.html)

<div class="collapse navbar-collapse" id="navbarNavDropdown"> <ul class="navbar-nav"> <li class="nav-item active"> <a class="nav-link" href="{% url 'index' %}">Inicio <span class="sr-only">(current)</span> </a> </li> <li class="nav-item"> <a class="nav-link" href="{% url 'peliculas' %}">Peliculas</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Directores</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Actores</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Géneros</a> </li> <li class="nav-item"> <a class="nav-link" href="127.0.0.1:8000/admin/">Administración</a> </li> </ul> </div>

我的urls.py文件:

My urls.py file:

from django.contrib import admin from django.urls import path, include, re_path from django.conf.urls import url from . import views app_name = "videoclub" urlpatterns = [ path('', views.index, name="index"), url(r'^peliculas/$', views.PeliculaListView.as_view(), name='peliculas'), # url(r'^pelicula/(?P<pk>\d+)$', views.DetailPeliculaView.as_view(), name='detalle-pelicula'), ]

先谢谢大家！

推荐答案

您已在 videoclubs 应用程序中为URL命名空间.因此，您应该使用 {％url'videoclub:peliculas'％}

You've namespaced your URLs in the videoclubs app. So rather than just {% url 'peliculas' %} you should use {% url 'videoclub:peliculas' %}
