模板不存在异常

Question

我对Django很陌生。我面临异常模板不存在在/处。我想我的模板目录有一些问题。

这是网址：

from django.conf.urls import url
from first_app import views
urlpatterns= [
    url(r'', views.index, name='index'),
]

以下是视图：

from django.shortcuts import render
from django.http import HttpResponse

def index(request):
    my_dict={'insert_me':"Hello I have created my first dynamic Template"}
    return render(request,'Twenty3rdMarch/first_app/templates/index.html',context=my_dict)

这是我的设置：

import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATES_DIR=os.path.join(BASE_DIR,'templates')
print(TEMPLATES_DIR)

请帮助我解决它。

Answer 1

将Twenty3rdMarch/first_app/templates/index.html更改为index.html。从 APP_DIRS 引用模板时不需要完整路径。

但是，我建议您正确命名模板目录。只需将index.html放入应用的模板目录中，就可能导致模板覆盖。您应该像这样在应用程序的模板目录中创建具有相同名称的目录。

myapp
  templates
    myapp
      index.html

然后像myapp/index.html一样引用它

您可以在主项目的文件夹下创建模板文件夹，并对settings.py进行此更改

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