python - 即使在 BASE_DIR 与 settings.py 中的模板连接后，如何修复 TemplatesDoesNotExist 错误？

Question

图 1- 错误

我notice Exception Value: registration/login.html ，我什至没有在模板中，相反，我有 sign-in.html，我不知道为什么它提到 login.html。请在下面查看我的模板文件夹作为图像 3-模板。

1. 我正在尝试修复上述错误。我的项目路径看起来像

图 2- 项目路径

图 3- 模板

1. 上图 2 显示我的模板文件夹位于 foodtaskerapp 文件夹中
2. 在 settings.py 中，我已'DIRS': [os.path.join(BASE_DIR, 'templates')],在 TEMPLATES 部分添加。
3. 我认为有一个错误，因为在我们可以从 BASE_DIR 获取模板之前，我们需要通过 foodtaskerapp。这导致我进入以下步骤
4. 在 settings.py 我尝试'DIRS': [os.path.join(BASE_DIR, 'foodtaskerapp','templates')],替换第 2 步
5. 完成上述步骤后，我也尝试了'DIRS': [os.path.join(BASE_DIR, 'foodtaskerapp\\templates')],. 我在这里使用了两个斜杠，因为当我使用交互式控制台中的打印命令时，我看到路径是以那种格式给出的。
6. 我还尝试将我的模板文件夹从 foodtaskerapp 移动到根文件夹，然后我检查如下以确认我是否在正确的路径中：

from django.conf import settings

print(settings.TEMPLATES)

然后我得到了

'DIRS': ['C:\\Users\\simple_tech\\Desktop\\foodtasker-master\\foodtasker-master\\templates']

以上表明我走在正确的道路上。

但是每当我在运行后单击服务器 URL 时，我仍然收到错误“TemplatesDoesNotExist”

python manage.py runserver

Django 没有“默认” login.html模板。在这里查看更多

登录视图 使用该 模板registration/login.html，就像您项目中的任何其他应用程序、第三个应用程序或在本例中为一个 contrib（内置）应用程序一样。您需要在已知路径中创建模板。在这种情况下路径 =registration/login.html

您所要做的就是，在您的模板根目录中创建另一个具有名称registration的目录，并在其中创建一个名为的模板文件login.html
