TemplateDoesNotExist位于/lab/

Question

在dashboar.html中，我扩展了base.html，它弹出一个错误，TemplateDoesNotExist at /lab/，如果我将{% TemplateDoesNotExist " base.html“%}去掉，它可以工作，假设我的base.html有问题。

这是我的目录

mysite/
  lab/
    templates/
      lab/
        base.html
        dashboard.html
        details/
          index.html
          login.html
    __init__.py
    # views.py; models.py etc.

base.html

<div id="header">
    <span class="logo">Bookmarks</span>
    {% if request.user.is_authenticated %} <ul class="menu">
        <li {% if section =="dashboard" %}class="selected"{% endif %}>
            <a href="{% url 'dashboard' %}">My dashboard</a>
        </li>
        <li {% if section =="images" %}class="selected"{% endif %}>
            <a href="#">Images</a>
        </li>
        <li {% if section =="people" %}class="selected"{% endif %}>
            <a href="#">People</a>
        </li> </ul> {% endif %}
    <span class="user">
{% if request.user.is_authenticated %}
    Hello {{ request.user.first_name }},
    <a href="{% url 'logout' %}">Logout</a>
    {% else %}
    <a href="{% url 'login' %}">Log-in</a>
    {% endif %}
    </span>
</div>

urls.py

from django.conf.urls import url
from . import views
from django.contrib.auth.views import login, logout, logout_then_login

urlpatterns = [
    # post views
    url(r'^login/$', login, name='login'),
    url(r'^logout/$', logout, name='logout'),
    url(r'^logout-then-login/$', logout_then_login, name='logout_then_login'),
    url(r'^$', views.dashboard, name='dashboard'),
]

更新：

我已经在我的settings.py中添加了以下内容

LOGIN_REDIRECT_URL = reverse_lazy('dashboard') 
LOGIN_URL = reverse_lazy('login')
LOGOUT_URL = reverse_lazy('logout')

Answer 1

解决方案:如下所示的扩展基本模板：{% extends 'lab/base.html' %}

说明：

如果您只编写{% extends 'base.html' %}，Django将在lab/templates/中查找base.html。但是在这个目录中没有。

实际上，base.html位于lab/templates/lab/目录中。这就是为什么您需要指定包含base.html的应用程序目录的名称
