Django模板不存在不检查顶级.html吗？

Question

我试图将Django指向mysite的顶级about.html，但是Django似乎并未在mysite / about.html，mysite / templates / about.html或mysite / templates / mysite /中检查文件about.html（我在所有这3个地方都放了about.html）

我收到TemplateDoesNotExist错误：

Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:
Using loader django.template.loaders.app_directories.Loader:
c:\users\jerry hou\documents\projects\django-trunk\django\contrib\admin\templates\about.html (File does not exist)
c:\users\jerry hou\documents\projects\django-trunk\django\contrib\auth\templates\about.html (File does not exist)
c:\Users\Jerry Hou\Documents\Projects\mysite\polls\templates\about.html (File does not exist)
 #Why doesn't check inside mysite\mysite\ but only in mysite\polls\?

这是Django mysite的文件目录结构：

mysite/
        manage.py
        polls/
        __init__.py
        admin.py
        migrations/
            __init__.py
        models.py
        tests.py
        views.py
        mysite/
            __init__.py
            settings.py
            urls.py
            wsgi.py

mysite / mysite / urls.py：

from django.conf.urls import include, url
from django.contrib import admin
from mysite import views

urlpatterns = [
    # Examples:
    url(r'^$', 'mysite.views.index', name='mysite_home'),
    url(r'^about/$', views.AboutView.as_view(), name='mysite_about'),
    url(r'^polls/', include('polls.urls', namespace = "polls")),
    url(r'^admin/', include(admin.site.urls)),

]

Answer 1

您应该在项目根目录中创建templates目录，并将以下设置添加到mysite/settings.py ：

TEMPLATE_DIRS = (
    os.path.join(BASE_DIR, 'templates'),
)

TEMPLATE_DIRS文档在这里 。

以下为我工作：

mysite/

├── manage.py
├── mysite
│   ├── __init__.py
│   ├── __pycache__
│   │      ...<omitted>...
│   ├── settings.py
│   ├── urls.py
│   ├── views.py
│   └── wsgi.py
└── templates

    url(r'^$', views.index),

    url(r'^admin/', include(admin.site.urls)),
)

为什么不检查mysite \\ mysite \\内部？

您可以通过将settings.py更改为django来做到这一点：

...

TEMPLATE_DIRS = (
    os.path.join(BASE_DIR, 'mysite/templates'),
)

...

...并在此处添加模板目录：

mysite
├── db.sqlite3
├── manage.py
├── mysite
│   ├── __init__.py
│   ├── __pycache__
│   │   ...<omitted>...
│   ├── settings.py
│   ├── templates
│   │   └── index.html

他们mysite / mysite / views.py看起来像这样：

from django.http import HttpResponse
from django.template import Context, loader

def index(request):
    #return HttpResponse('hello world')

    templ = loader.get_template('index.html') #Use the path within the templates dir 
    context = Context(
        {'planet': 'world'}
    )
    return HttpResponse(
        templ.render(context)
    )
