Question

我知道有人问过，但是，这有所不同，请看下面：我刚刚创建了一个非常简单的测试项目，文件夹结构是这样的：

忽略红色标记，这是因为，据说它没有检测到元编程问题。

为了简单起见，我已经在主页本身调用了视图，主要项目urls.py有网址：

"""testproject URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, re_path
from test1.views import test1_detail

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path('^$', test1_detail)
]

tag_detail1视图文件就是这样：

from django.shortcuts import render

from test1.models import model_test1 as Model
from django.shortcuts import render

def test1_detail(request):

    tag = Model.objects.get(name__iexact='birlaman')
    return render(request,
            'test1/test.html',
            {'tag':tag})

模型数据库只是一个简单的数据库：

from django.db import models


class model_test1(models.Model):

    name = models.CharField(max_length=31)
    age = models.TextField()

我在数据库中创建了一些数据：

settings.py是：

base.html位于模板文件夹中，配置如下： os.path.join（BASE_DIR，'template'）。它包含简单的html：

<!DOCTYPE html>

    <title>
        <head>Some head title</head>
    </title>

    <body>
        {%block content%}
            Some default content
        {%endblock%}
    </body>

</html>

base_test1.html只有一行：

{%extends parent_template|default:"base.html"%}

而且test.html只有：

{%extends parent|default:"test1/base_test1.html"%}

{% block content %}
    <h1>test succeeded</h1>
    <p>
        The tag is: {{tag.name}}
    </p>
{% endblock %}

现在，与项目运作相关的每个文件都完全在上面给出，您可以验证的所有文件都在正确的位置。现在，如果它是django 2.0中的一个错误，它将是一个不同的东西，但是在我点击之后，世界上的什么给了我以下错误：./ manage.py runserver

Template loader postmortem
Django tried loading these templates, in this order:

Using engine django:
    * django.template.loaders.filesystem.Loader: /home/liz/Documents/testproject/templates/test1/test.html (Source does not exist)
    * django.template.loaders.app_directories.Loader: /home/liz/DocFolder1/DocFolder1/Environments/django2/lib/python3.5/site-packages/django/contrib/admin/templates/test1/test.html (Source does not exist)
    * django.template.loaders.app_directories.Loader: /home/liz/DocFolder1/DocFolder1/Environments/django2/lib/python3.5/site-packages/django/contrib/auth/templates/test1/test.html (Source does not exist)

请告诉我问题是什么，已经有2天我试图解决这个问题，我已经多次重新制作了这个项目，但它并没有让步。网上有类似的问题，但提到的解决方案不起作用。

EDIT ---------------------------------------------- --- 我在test1文件夹下添加了一个urls.py并添加了代码：

from django.urls import re_path
from organizer.views import test1_detail



urlpatterns = [
    re_path('^$', tag_detail)
]

并且在主urls.py中我使用了这个：

from django.contrib import admin
from django.urls import path, re_path
from django.urls import re_path, include
from test1 import urls as test1_url

urlpatterns = [
    re_path('admin/', admin.site.urls),
    re_path('^', include(test1_url))

]

但是，它仍然无法解决问题。

Answer 1

您尝试从主urls.py加载模板，而不是从test1 app urls.py中加载模板。因此，模板加载器不会查看test1 / templates。

请注意错误消息：

django.template.loaders.filesystem.Loader: /home/liz/Documents/testproject/templates/test1/test.html (Source does not exist)

从应用程序中调用视图或将模板移动到testproject / templates文件夹。

模板不存在。一切都是正确的但是没有工作
