模板不存在 django

Question

在此处输入图像描述我目前正在参加有关 django 的在线课程，并且现在正在处理第 3 部分中的模板，我按照说明进行操作，但每次我去mysite/polls， 我收到“不存在模板”错误。
这是我的投票/view.py。

from django.http import HttpResponse

from .models import Question

from django.shortcuts import render

from django.http import Http404



def index(request):
    latest_question_list = Question.objects.order_by('-pub_date')[:5]
    context = {'latest_question_list': latest_question_list}
    return render(request, 'polls/index.html', context)
def owner(request):
 return HttpResponse("Hello, world. 9d5a197b is the polls index.")

def detail(request, question_id):
    try:
        question = Question.objects.get(pk=question_id)
    except Question.DoesNotExist:
        raise Http404("Question does not exist")
    return render(request, 'polls/detail.html', {'question': question})

def results(request, question_id):
    response = "You're looking at the results of question %s."
    return HttpResponse(response % question_id)

def vote(request, question_id):
    return HttpResponse("You're voting on question %s." % question_id)

/polls/urls.py

from . import views

urlpatterns = [
    # ex: /polls/
    path('', views.index, name='index'),
    # ex: /polls/5/
    path('<int:question_id>/', views.detail, name='detail'),
    # ex: /polls/5/results/
    path('<int:question_id>/results/', views.results, name='results'),
    # ex: /polls/5/vote/
    path('<int:question_id>/vote/', views.vote, name='vote'),
    path('owner', views.owner, name='owner'),

Answer 1

添加模板 -包含您的HTML页面的目录-到DIRS。

看起来像这样：

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

]

Answer 2

首先你必须在你的 setting.py 中告诉 django 在你的项目中寻找模板的路径

在你的 settings.py 中输入路径

BASE_DIR = Path(__file__).resolve().parent.parent
TEMPLATES_DIR = BASE_DIR / 'templates'

然后在

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

在您的模板设置中像这样传递您的模板路径，然后在 manage.py 退出的同一文件夹中创建一个文件夹名称模板并将所有模板复制粘贴到那里 然后你就可以继续下去了 告诉我你是否还有错误
