【问题描述】：

我有一个应用程序，根据其类别，租户可以通过/dashboard/templates/dashboard 或/dashboard2/templates/dashboard2 定向到应用程序（和模板）。

不知何故，对于dashboard2，Django 找不到该应用程序，它试图在dashboard 下找到这些模板。

这是一个dashboard2/views.py

@method_decorator(login_required, name='dispatch')
class SupplierPage2(LoginRequiredMixin,APIView):
    def get(self, request, *args, **kwargs):
        query = request.GET.get('search_ress', None)
        print(query)
        context = {}

        #if query and request.method == 'GET':
        Supplier = supplier2.objects.filter(supplier = query)
        print(Supplier)
       
        labels = Item2.objects.filter(fournisseur = query).values_list('reference', flat=True)[:10]
        print(labels)
        default_items = Item2.objects.filter(fournisseur = query).values_list('number_of_sales', flat=True)[:10]
        print(default_items)
        label1s = Item2.objects.filter(fournisseur = query).values_list('reference', flat=True)[:10]
        print(label1s)
        default_item1s = Item2.objects.filter(fournisseur = query).values_list('number_of_orders_placed', flat=True)[:10]
        print(default_item1s)
            
        context.update({'Supplier' : Supplier, 'labels':labels, 'default_items':default_items,'label1s':label1s, 'default_item1s':default_item1s})


        return render(request, 'Supplier2.html',context)

和错误：

TemplateDoesNotExist at /Supplier2.html
Supplier2.html
Request Method: GET
Request URL:    https://uname.website.net/Supplier2.html
Django Version: 3.0.5
Exception Type: TemplateDoesNotExist
Exception Value:    
Supplier2.html

和追溯：

Template-loader postmortem
Django tried loading these templates, in this order:

Using engine django:

django.template.loaders.filesystem.Loader: /home/ubuntu/website/dashboard/templates/dashboard/dashboard2/templates/dashboard2/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/website/customers/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/django/contrib/auth/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/website/dashboard/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/website/tenantlogin/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/website/uploadfiles/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/django_tenants/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/rest_framework/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/django_tables2/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/website/dashboard2/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/django/contrib/admin/templates/Supplier2.html (Source does not exist)
django.template.loaders.app_directories.Loader: /home/ubuntu/exo/lib/python3.6/site-packages/crispy_forms/templates/Supplier2.html (Source does not exist)

当尝试指定 /dashboard2/Supplier2.html 时，我仍然在 Django 中遇到同样的错误：

TemplateDoesNotExist at /Supplier2.html
/dashboard2/Supplier2.html

这是我在 settings.py 中的模板：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, "dashboard/templates/dashboard", "dashboard2/templates/dashboard2")],
        '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',
                'django.template.context_processors.i18n'
            ],
        },
    },
]

在这一点上，我不知道还能尝试什么

【问题讨论】：

此模板路径已磨损/home/ubuntu/website/dashboard/templates/dashboard/dashboard2/templates/dashboard2/Supplier2.htmt 提供模板设置定义可能会有所帮助。
刚刚添加了我在 settings.py 中关于模板的内容

标签： python django templates django-templates django-settings

【解决方案1】：

修正如下设置：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, "dashboard/templates/dashboard"), os.path.join(BASE_DIR,"dashboard2/templates/dashboard2")],
        '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',
                'django.template.context_processors.i18n'
            ],
        },
    },
]
