Django无法找到模板

问题描述

所以，试图设置一个django设置模块来检查环境变量和加载设置。

我的设置模块看起来像

  / templates 
 home.html 
 
 / settings 
 base.py 
 prod.py 
 dev.py 
 test.py 
  

base.py

  PROJECT_ROOT = os.path.abspath（os.path.dirname（__ file__））
 
 TEMPLATE_DIRS = [
 os.path.join（PROJECT_ROOT，templates），
] 
 
 urls.py 
 
 from django.views.generic.simple import direct_to_template 
 
 urlpatterns = patterns（''，
 url ^ $，direct_to_template，{'template'：'home.html'}，name =home），
）
  

当我将所有的设置都放在一个文件中时，这个功能很好，但是由于我把这些文件分开，我得到错误：

/

home.html

模板加载程序postmortem

Django尝试加载这些模板，按此顺序：
使用加载器django.template.lo aders.filesystem.Loader：
/Users/Tulsa/Apps/tulsa-applications-co/tulsa/tulsa/settings/templates/home.html（文件不存在）
使用加载器django.template。 loaders.app_directories.Loader：
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/django/contrib/auth/templates/home.html（档案不存在）
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/django/contrib/admindocs/templates/home.html（档案不存在）
/Users/Tulsa/.Apps/ tulsa_io / lib / python2.7 / site-packages / grappelli / templates / home.html（文件不存在）
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/django /contrib/admin/templates/home.html（文件不存在）
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/pagination/templates/home.html（File does不存在）
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/djangosaml2/templates/home.html（文件不存在）
/ Users / Tulsa / Apps /塔尔萨应用-CO /塔尔萨/塔尔萨/应用/型材/模板/坎e.html（文件不存在）
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/debug_toolbar/templates/home.html（文件不存在）

使用加载器django.template.loaders.eggs.Loader：

我在这里缺少什么

解决方案

将您的 PROJECT_ROOT 更改为：

  PROJECT_ROOT = os.path.dirname（os.path.dirname（os.path.abspath（__ file__）））
  

并确保您的 TEMPLATE_LOADERS 变量设置正确。

说明：

abspath base.py 的完整路径，即 /home/some-path/project-folder/settings/base.py

因此，首先 dirname 为您提供给定路径的路径名（以上获得），即， / home / some-path / project-folder / settings /

然后，第二个 dirname 给你给定路径的路径名（上面获得），即 / home / some-path / project-folder /

所以，现在当你加入这个路径到 templates 时，一切都开始工作正常。

So ive been trying to setup a django settings module that will check the environment variable and load settings.

Heres what my settings module looks like

/templates
    home.html

/settings
    base.py
    prod.py
    dev.py
    test.py

base.py

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))

TEMPLATE_DIRS = [
os.path.join(PROJECT_ROOT, "templates"),
]

urls.py

from django.views.generic.simple import direct_to_template

urlpatterns = patterns('',
url(r"^$", direct_to_template, {'template' : 'home.html' }, name="home"),
)

When I had all of my settings in one file, this worked just fine, but since I split the files up I get the error:

TemplateDoesNotExist at /

home.html

Template-loader postmortem

Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:
/Users/Tulsa/Apps/tulsa-applications-co/tulsa/tulsa/settings/templates/home.html (File does not exist)
Using loader django.template.loaders.app_directories.Loader:
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/django/contrib/auth/templates/home.html (File does not exist)
/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/django/contrib/admindocs/templates/home.html (File does not exist)

/Users/Tulsa/.Apps/tulsa_io/lib/python2.7/site-packages/debug_toolbar/templates/home.html (File does not exist)

Using loader django.template.loaders.eggs.Loader:

what am i missing here?

解决方案

Change your PROJECT_ROOT to:

PROJECT_ROOT = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

And make sure your TEMPLATE_LOADERS variable is set properly.

Explanation:

abspath gives you the full path of the base.py, i.e., /home/some-path/project-folder/settings/base.py

Therefore, first dirname gives you the dir path name of the given path (obtained above), i.e., /home/some-path/project-folder/settings/

And then, the second dirname gives you the dir path name of the given path (obtained above), i.e., /home/some-path/project-folder/

So, now when you join this path to templates, everything starts working fine.
