【中文标题】TemplateDoesNotExist at /base/index.html 部署到heroku时【英文标题】:TemplateDoesNotExist at / base/index.html when deploying to heroku 【发布时间】:2016-12-07 02:48:46 【问题描述】:我已经研究这个问题好几天了,我真的很想在这里得到一些真正的帮助! :)
我是 Python、Django 和 *** 的新手,所以请告诉我更多信息或其他格式是否会有所帮助。
我正在尝试在 Heroku 上部署我的应用程序。它在本地运行,但是当我尝试
heroku 打开
我收到以下错误:
模板不存在于 / 基础/index.html
我已经看到其他人发生这种情况,并且我尝试了以下没有奏效的修复:
通过将 index.html 直接放入模板而不是模板来更改文件夹结构>base>index.html (TemplateDoesNotExist when base template is in root folder) - 这会导致应用程序停止在本地运行 通过添加 将模板添加为已安装的应用程序(就像我为核心所做的那样)(r'', 包括('templates.urls')),
到我的 urls.py
并添加了
'模板'
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。
将我的 views.py 更改为: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
检查以确保我有标准的 Django 1.8x 模板设置 (TemplateDoesNotExist at / base/index.html) 尝试将我的 views.py 更改为: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')],
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)
我在想我可能需要定义一个 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。

【问题讨论】:
【参考方案1】:在您的TEMPLATES
设置中,尝试将您的DIRS
设置更改为:
'DIRS': [os.path.join(BASE_DIR, 'templates')],
这是通常的方法,我看不出有任何理由像你现在那样使用MAIN_DIR
。
保持模板为
template_name = "base/index.html"
【讨论】:
非常感谢!!!那行得通!在 Heroku 上没有 CSS 的情况下它会通过,但我可能会弄清楚如何解决这个问题。非常感谢!!!!【参考方案2】:我遇到了这个问题,因为我在我的 HTML 模板名称中使用了驼峰式,但是用小写字母来调用它。将模板名称更改为小写,并且有效。
【讨论】:
【参考方案3】:我也有这个问题。问题是我有:
'DIRS': [os.path.join(BASE_DIR, 'templates')],
在我的 settings.py 中,而不是:
'DIRS': [os.path.join(BASE_DIR, 'Templates')],
模板目录有一个大写的 T,但我在 settings.py 中输入了一个小写的 t。
