Question

我已经在这个问题上工作了好几天，我真的很想在这里得到一些真正的帮助！：）

我是Python，Django和stackoverflow的新手，所以如果有更多信息或其他格式有用，请告诉我。

我试图在Heroku上部署我的应用。它在本地运行，但是当我尝试

时

heroku open

我收到以下错误：

在/的TemplateDoesNotExist 碱/ index.html中

我已经看到这种情况发生在其他人身上，而且我已经尝试了以下修复工具：

通过将index.html直接放入模板而不是模板＆gt; base＆gt; index.html来更改文件夹结构（TemplateDoesNotExist when base template is in root folder） - 这会导致应用停止在本地运行
- 通过添加

（r＆＃39;＆＃39;，include（＆＃39; templates.urls＆＃39;）），

到我的urls.py

并添加了

＆＃39;模板＆＃39;

到我的settings.py。这导致应用程序停止在本地运行，因此我将其更改回来。

改变了我的views.py：

from django.shortcuts import render from django.views.generic.base
import TemplateView
# Create your views here. class LandingView(TemplateView):
   template_name = "base/index.html"

到

from django.shortcuts import render
from django.views.generic.base import TemplateView
# Create your views here.
class LandingView(TemplateView):  
    template_name = [os.path.join(MAIN_DIR, 'coffeedapp2/templates')],

检查以确保我有标准的Django 1.8x模板设置（TemplateDoesNotExist at / base/index.html）
- 尝试更改我的views.py：

from django.shortcuts import render
from django.views.generic.base import TemplateView
# Create your views here.
class LandingView(TemplateView):
  template_name = "base/index.html"

到

from django.shortcuts import render
from django.views.generic.base import TemplateView
# Create your views here.
class LandingView(TemplateView):
  template_name = "base/index.html"

（TemplateDoesNotExist at / at templates/index.html）

我认为我可能需要定义SITE_ROOT或其他东西，但每当我尝试这样做时它就会停止在本地运行。

Answer 1

在TEMPLATES设置中，尝试将DIRS设置更改为：

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

这是通常的方法，我看不出你目前使用MAIN_DIR的任何理由。

将模板保留为

template_name = "base/index.html"

Answer 2

我遇到了这个问题，因为我在 HTML 模板名称中使用了驼峰命名法，但使用小写法调用它。将模板名称更改为小写并且它起作用了。

部署到heroku时，/ base / index.html上的TemplateDoesNotExist
