Django:/ Login /上的TemplateDoesNotExist(源不存在)

时间:2018-03-03 13:25:05

标签: python django templates login

我试图进入Django并且我在这里和那里按照教程进行操作。我试图从官方的Django教程中添加一个登录页面到轮询应用程序,但即使我在this simple tutorial跟随这封信,我收到了TemplateDoesNotExist错误。据我所知,Django正在寻找正确目录中的login.html并给出消息Source不存在。

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

Using engine django:

django.template.loaders.filesystem.Loader: /home/kostis/PycharmProjects/secvot/templates/registration/login.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/kostis/PycharmProjects/secvot/voting/templates/registration/login.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/kostis/.virtualenvs/secretvoting/local/lib/python2.7/site-packages/django/contrib/admin/templates/registration/login.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/kostis/.virtualenvs/secretvoting/local/lib/python2.7/site-packages/django/contrib/auth/templates/registration/login.html (Source does not exist)

据我所知,Django尝试加载正确的模板,查看正确的文件夹,但显示错误&#34; Source不存在&#34;事件,虽然模板在那里。

关于我可能做错的任何想法?

2 个答案:

答案 0 :(得分:2)

'DIRS': [os.path.join(BASE_DIR, 'templates')],

这告诉Django在项目目录中查找templates目录(包含manage.py的目录。但是你的模板目录在你的内部项目目录中(包含settings.py的目录)。

您可以通过执行以下操作之一来解决此问题:

  1. 移动模板目录
  2. DIRS设置更改为指向模板目录的当前位置。

    'DIRS': [os.path.join(BASE_DIR, 'secvot', 'templates')],
    
  3. secvot添加到INSTALLED_APPS,以便app_directories加载程序找到模板目录。如果您这样做,可以将DIRS更改为[]

答案 1 :(得分:0)

这是拼写错误!

在我的情况下,错误是

异常类型:TemplateDoesNotExist

异常值:blog / blog_form.html

奇怪的是,我什至没有创建这个blog_form.html文件。

那是什么愚蠢的错误?

我在views.py文件中提到了template_name为tempplate_name(参见拼写)。

我花了30多分钟才发现这个错误,因为大多数人都有快速阅读的习惯(而不是逐字阅读)。我也找不到那个blog_form.html文件(甚至不存在,并且大部分时间都因为这个文件而浪费了)。因此,我建议您返回并发现该拼写错误。它对我有用,我希望它也对您有用,因为我知道它令人沮丧。
