python - Django渲染无法找到实际存在的模板

Question

我的 Django 项目中有以下 View :

import os
from django.shortcuts import render
from JumboDjango import settings

# Create your views here.
def index(request):
    filename = os.path.join(settings.BASE_DIR, 'frontend/source/public/index.html')
    return render(request, filename)

但是，当调用它时，它会引发以下异常:

Internal Server Error: /
Traceback (most recent call last):
  File "/Users/hugovillalobos/Documents/Code/JumboDjangoProject/JumboDjangoVenv/lib/python3.7/site-packages/django/core/handlers/exception.py", line 34, in inner

    content = loader.render_to_string(template_name, context, request, using=using)
  File "/Users/hugovillalobos/Documents/Code/JumboDjangoProject/JumboDjangoVenv/lib/python3.7/site-packages/django/template/loader.py", line 61, in render_to_string
    template = get_template(template_name, using=using)
  File "/Users/hugovillalobos/Documents/Code/JumboDjangoProject/JumboDjangoVenv/lib/python3.7/site-packages/django/template/loader.py", line 19, in get_template
    raise TemplateDoesNotExist(template_name, chain=chain)

您可以在下图中看到 /Users/hugovillalobos/Documents/Code/JumboDjangoProject/JumboDjango/frontend/source/public/index.html 实际存在:

我不知道我是否缺少任何 Django 配置或其他内容。

这是我的模板设置:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

首先，您应该始终将 html 文件和静态文件(css、js、json)分开。

这对我来说是一个很好的方法，我一直使用。对于 HTML 文件，在项目文件夹中定义模板目录。

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        .
        .
        .

    },
]

此templates文件夹应位于项目目录中。在此文件夹中，您可以为您的应用程序或任何内容创建文件夹。就像当前的情况一样，templates 中有一个 public 文件夹，里面有 html 文件。您可以像这样访问该文件:

return render(request, 'public/index.html')

---编辑------

对于这个问题的条件，如果public是我们将拥有所有html文件的文件夹，并且JumboDjango是项目目录，那么:

settings.py

TEMPLATES = [
        {
            'BACKEND': 'django.template.backends.django.DjangoTemplates',
            'DIRS': [os.path.join(BASE_DIR, 'frontend/source/public/')],
            .
            .
            .

        },
    ]

views.py

return render(request, 'index.html')

如果我们在 public 中创建另一个文件夹，例如 folder1，那么

return render(request, 'folder1/index.html')

但是静态文件需要单独的文件夹。
