存在模板时的 Django 3.1 TemplateNotFound 异常

Question

我正在努力部署我的应用程序并在 Windows 上完成了我的大部分工作。但是，现在我已将其移至 AWS，它不再工作了。

在任何人链接其他文章之前，这里是我尝试过的所有事情的列表：

• 将os.path.join(BASE_DIR,'templates') 添加到TEMPLATE_DIR
• 更改我的模板的权限
• 我的应用在我的 INSTALLED_APPS 变量中
• 我检查了我所有的render 方法的格式是否正确
• 完全重新下载了我的项目

就像我之前说的，它可以在我的 Windows 机器上运行，但不能在 AWS 或我的 Mac 上运行。更奇怪的是错误说

Django tried loading these templates, in this order:

Using engine django:
    * django.template.loaders.filesystem.Loader: /opt/bitnami/apps/django/django_projects/goFiles/uploads/templates/uploads/base.html  (Source does not exist)
    * django.template.loaders.app_directories.Loader: /opt/bitnami/apps/django/django_projects/goFiles/uploads/templates/uploads/base.html  (Source does not exist)
    * django.template.loaders.app_directories.Loader: /opt/bitnami/python/lib/python3.8/site-packages/django/contrib/admin/templates/uploads/base.html  (Source does not exist)
    * django.template.loaders.app_directories.Loader: /opt/bitnami/python/lib/python3.8/site-packages/django/contrib/auth/templates/uploads/base.html  (Source does not exist)

/opt/bitnami/apps/django/django_projects/goFiles/uploads/templates/uploads/base.html 是我正在寻找的模板的正确绝对路径。如果我尝试使用该绝对路径cat 那个文件，它会打印到stdout。话虽如此，我将包含我的一些代码以供严格审查。

views.py

def get(self, request, *args, **kwargs):
        paste = None
        return render(request, 'uploads/index.html', {'paste': paste})

    def post(self, request, *args, **kwargs):
        paste = request.POST
        if is_post_valid(request):
            return upload(request)
        return render(request, 'uploads/index.html', {'paste': paste})

INSTALLED_APPS

INSTALLED_APPS = [
    'uploads.apps.UploadsConfig',

    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

模板

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['/opt/bitnami/apps/django/django_projects/goFiles/uploads/templates/uploads/'],

                'django.contrib.messages.context_processors.messages',

如果我需要提供更多信息，我很乐意这样做。任何帮助将不胜感激。

##django模板根目录可以使用子目录模板文件

settings.py

确保使用前定义的“BASE_DIR”

在项目内部构建路径，如下所示：BASE_DIR / 'subdir'。

BASE_DIR = Path(__file__).resolve().parent.parent

更新'DIRS'：[BASE_DIR,'templates'],

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR ,'templates'],
        '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',
            ],
        },
    },
]

在您的项目根文件夹中创建模板目录。

在模板文件夹中创建子目录。 “blogs”是我的子目录

view.py

def post_list(request):
    posts = Post.published.all()
    return render(request,'blogs/post_list.html',{'posts':posts})

你在扩展的末尾添加了额外的空间，我手动尝试了 django 不允许任何额外的空间

from:
    {% extends "uploads/base.html "%} 
                                 ^
to:
    {% extends "uploads/base.html" %} 
                                 ^
