Django error saying TemplateDoesNotExist at/

I have an error on my Django Project. The templates folder doens't work. I have the project like this:
├── manage.py
├── myProjet
│ ├── __init__.py
│ ├── settings.py
│ ├── templates
│ ├── urls.py
│ ├── wsgi.py
│ └── wsgi.pyc
├── app1
├── templates
So, I want to use the templates forlder. The template filder is on "/myProjet/templates", not on: "/myProjet/myProjet/templates." The settings.py file is this:
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'app1',
]
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [ os.path.join( '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',
],
},
},
]
And, the error is raised on the signup function. The singup function is:
def SignupPage(request):
if request.method=='POST':
uname=request.POST.get('username')
email=request.POST.get('email')
pass1=request.POST.get('password1')
pass2=request.POST.get('password2')
if pass1!=pass2:
return HttpResponse("Your password and confrom password are not Same!!")
else:
my_user=User.objects.create_user(uname,email,pass1)
my_user.save()
return redirect('login')
return render (request,'signup.html')
The error information is this. I have tried to change the base_path in a lot of ways but I always have this error :
TemplateDoesNotExist at /
signup.html
Request Method: GET
Request URL: http://127.0.0.1:8000/

'/home/myPC/myProject/my_env/lib/python3.8/site-packages']
I don't know how to correct the erorr. I have a 3.8 python version and 4.1.6 DJango version.

You can use separate folder for templates but you need to probably fix the DIR in TEMPLATES as follows:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [ os.path.join(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',
],
},
},
]

try
'DIRS': [ os.path.join(BASE_DIR,'templates')],
or at least give the full path depending where templates should be.
By the way: the error message "TemplateDoesNotExist at /" is missleading as the "/" is not a search path. You always get that message whenever a template is missing that you address like "xyz.html".
TemplateDoesNotExist at /
signup.html
Below the error message that you have posted you should get the info about where the template has been searched for ... something like this:
Template-loader postmortem
Django tried loading these templates, in this order:
Using engine django:
django.template.loaders.filesystem.Loader: C:\ ..... # because of 'DIRS': ...
django.template.loaders.app_directories.Loader: C:\ ..... # because of 'APP_DIRS': True,
django.template.loaders.app_directories.Loader: C:\ ..... # because of 'APP_DIRS': True,

TemplateDoesNotExist at / Exception Value: index.html django

welcome
i make a new project and i put index.html in templates dirctory and when i runserver i got the message TemplateDoesNotExist at / where the mistake i done
there is the views.py
from django.shortcuts import render, redirect
def index(request):
return render(request,'index.html')
there is the urls.py
from django.contrib import admin
from django.urls import path
from . import views
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.index,name='index'),
]
and there is the sitting.py
import os
from pathlib import Path
# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent
TEMPLATES_DIR = os.path.join(BASE_DIR, 'templates')
STATIC_DIR = os.path.join(BASE_DIR, 'static')
the templates_dir and static_dir i add it after make project

just add TEMPLATES_DIR inside TEMPLATES in settings.py file.
Example:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [TEMPLATES_DIR], #Added here
'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',
],
},
},
]
And see if it solves that error

How can I view my HTML page in Python using Django

I'm new into creating projects in Python using Django.
I'm creating a website in Python using the Django framework.
I've created an "index" function in the "views.py" file to render the "index.html" file present in the "templates" folder.
Below is the code for the "views.py" file.
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def index(request):
return render(request,"index.html",{})
I've also added the navigation for the "index" page.
Below is the code for "urls.py" file.
from django.contrib import admin
from django.urls import path
from gallery import views
urlpatterns = [
path('admin/', admin.site.urls),
path('index/', views.index,name="index")
]
Below is the code of templates section in settings.py file.
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR,'templates'),], #path to templates folder in local system.
'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',
],
},
},
]
But when I try to open the "index" page URL, I'm not able to view the page.
Error screenshot for reference
Folder structure for reference:-
Gallery_Website
|--gallery
|_ __init__.py
|_ admin.py
|_ apps.py
|_ models.py
|_ tests.py
|_ views.py
|--Gallery_Website
|_ __init__.py
|_ settings.py
|_ urls.py
|_ wsgi.py
|--templates
|_ index.html
|--db.sqlite3
|--manage.py
What could be wrong while defining the navigation for the "index" page?
Let me know if any other information is required.

You have to remove 'index/' in urls.py
Correct Code:
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.index,name="index")
]

In your settings.py file, add a value to you template dictionary key -- DIRS=[]
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(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',
],
},
},
]
then create a folder "templates" where "manage.py" file resides. And in that templates folder, create a file "index.html". Then you will be a able to see your html page.

How do I properly structure Templates and include them in the settings in Django 1.8.6?

So, here is my current structure:
django_project/
home_app/
__init__.py
migrations/
templates/
home_app/
base.html
admin.py
models.py
views.py
project_backend/
__init__.py
settings.py
url.py
wsgi.py
Now in home_app/views.py I have this very simple piece of code:
from django.views.generic import TemplateView
class HomeView(TemplateView):
template_name = "home/base.html"
and in the settings.py I set up my templates like this:
import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [
os.path.join(BASE_DIR, 'home_app', 'templates'),
# os.path.join(BASE_DIR, 'app_name', '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',
],
},
},
]
This works fine, and I am quite happy using the app/templates/app/some_temp.html approach, but this only works when I include the OS.path.joins for all the apps and templates, as far as I can see. Is there a way to register this structure in the settings by default and I am just overlooking it?
This is just no very pretty and I feel like it would be bad practice to write that down for every single app.:
os.path.join(BASE_DIR, 'home_app', 'templates')

You have 'APP_DIRS': True, so you shouldn't have to edit DIRS to use templates in the home_app/templates/ directory, as long as home_app is in your installed apps.
If you have a template,
home_app/templates/home_app/base.html
then you should use it with:
template_name = "home_app/base.html"
You currently have,
template_name = "home/base.html"
which isn't consistent.

Django TemplateDoesNotExist?

My local machine is running Python 2.5 and Nginx on Ubuntu 8.10, with Django builded from latest development trunk.
For every URL I request, it throws:
TemplateDoesNotExist at /appname/path appname/template_name.html
Django tried loading these templates, in this order:
* Using loader django.template.loaders.filesystem.function:
* Using loader django.template.loaders.app_directories.function:
TEMPLATE_DIRS
('/usr/lib/python2.5/site-packages/projectname/templates',)
Is it looking for /usr/lib/python2.5/site-packages/projectname/templates/appname/template_name.html in this case? The weird thing is this file does existed on disk. Why can't Django locate it?
I run the same application on a remote server with Python 2.6 on Ubuntu 9.04 without such problem. Other settings are the same.
Is there anything misconfigured on my local machine, or what could possibly have caused such errors that I should look into?
In my settings.py, I have specified:
SETTINGS_PATH = os.path.normpath(os.path.dirname(__file__))
# Find templates in the same folder as settings.py.
TEMPLATE_DIRS = (
os.path.join(SETTINGS_PATH, 'templates'),
)
It should be looking for the following files:
/usr/lib/python2.5/site-packages/projectname/templates/appname1/template1.html
/usr/lib/python2.5/site-packages/projectname/templates/appname1/template2.html
/usr/lib/python2.5/site-packages/projectname/templates/appname2/template3.html
...
All the above files exist on disk.
Solved
It works now after I tried:
chown -R www-data:www-data /usr/lib/python2.5/site-packages/projectname/*
It's strange. I don't need to do this on the remote server to make it work.

First solution:
These settings
TEMPLATE_DIRS = (
os.path.join(SETTINGS_PATH, 'templates'),
)
mean that Django will look at the templates from templates/ directory under your project.
Assuming your Django project is located at /usr/lib/python2.5/site-packages/projectname/ then with your settings django will look for the templates under /usr/lib/python2.5/site-packages/projectname/templates/
So in that case we want to move our templates to be structured like this:
/usr/lib/python2.5/site-packages/projectname/templates/template1.html
/usr/lib/python2.5/site-packages/projectname/templates/template2.html
/usr/lib/python2.5/site-packages/projectname/templates/template3.html
Second solution:
If that still doesn't work and assuming that you have the apps configured in settings.py like this:
INSTALLED_APPS = (
'appname1',
'appname2',
'appname3',
)
By default Django will load the templates under templates/ directory under every installed apps. So with your directory structure, we want to move our templates to be like this:
/usr/lib/python2.5/site-packages/projectname/appname1/templates/template1.html
/usr/lib/python2.5/site-packages/projectname/appname2/templates/template2.html
/usr/lib/python2.5/site-packages/projectname/appname3/templates/template3.html
SETTINGS_PATH may not be defined by default. In which case, you will want to define it (in settings.py):
import os
SETTINGS_PATH = os.path.dirname(os.path.dirname(__file__))

Find this tuple:
import os
SETTINGS_PATH = os.path.dirname(os.path.dirname(__file__))
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',
],
},
},
]
You need to add to 'DIRS' the string
os.path.join(BASE_DIR, 'templates')
So altogether you need:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(SETTINGS_PATH, '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',
],
},
},
]

If you encounter this problem when you add an app from scratch. It is probably because that you miss some settings. Three steps is needed when adding an app.
1、Create the directory and template file.
Suppose you have a project named mysite and you want to add an app named your_app_name. Put your template file under mysite/your_app_name/templates/your_app_name as following.
├── mysite
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── your_app_name
│   ├── admin.py
│   ├── apps.py
│   ├── models.py
│   ├── templates
│   │   └── your_app_name
│   │   └── my_index.html
│   ├── urls.py
│   └── views.py
2、Add your app to INSTALLED_APPS.
Modify settings.py
INSTALLED_APPS = [
...
'your_app_name',
...
]
3、Add your app directory to DIRS in TEMPLATES.
Modify settings.py.
Add os import
import os
TEMPLATES = [
{
...
'DIRS': [os.path.join(BASE_DIR, 'templates'),
os.path.join(BASE_DIR, 'your_app_name', 'templates', 'your_app_name'),
...
]
}
]

In setting .py remove TEMPLATE_LOADERS and TEMPLATE DIRS Then ADD
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': ['/home/jay/apijay/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',
],
},
},
]

I had an embarrassing problem...
I got this error because I was rushing and forgot to put the app in INSTALLED_APPS. You would think Django would raise a more descriptive error.

As of Django version tested on version 3, You need to add your new app to installed app. No other code change is required for a django app
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'addyourappnamehere'
]

For the django version 1.9,I added
'DIRS': [os.path.join(BASE_DIR, 'templates')],
line to the Templates block in settings.py
And it worked well

Django TemplateDoesNotExist error means simply that the framework can't find the template file.
To use the template-loading API, you'll need to tell the framework where you store your templates. The place to do this is in your settings file (settings.py) by TEMPLATE_DIRS setting. By default it's an empty tuple, so this setting tells Django's template-loading mechanism where to look for templates.
Pick a directory where you'd like to store your templates and add it to TEMPLATE_DIRS e.g.:
TEMPLATE_DIRS = (
'/home/django/myproject/templates',
)

May, 2022 Update:
As long as you follow this tutorial properly, you don't need to change(touch) the default settings of "TEMPLATES" in "settings.py" as shown below:
# "core/settings.py"
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",
],
},
},
]
And again, as long as you follow this tutorial properly, "templates" can be read properly under application folders as shown below:
root
├── core
│   ├── settings.py
│   ├── urls.py
│   ...
├── myapp1
│   ├── templates
│   │   └── myapp1
│   │   └── myapp1.html
│   ├── urls.py
│   ├── views.py
│ ...
├── myapp2
│   ├── templates
│   │   └── myapp2
│   │   └── myapp2.html
│   ├── urls.py
│   ├── views.py
│ ...
And "templates" can be read properly under a root django project folder as shown below:
root
├── core
│   ├── settings.py
│   ├── urls.py
│   ...
├── myapp1
│   ├── urls.py
│   ├── views.py
│ ...
├── myapp2
│   ├── urls.py
│   ├── views.py
│ ...
├── templates
│   ├── myapp1
| | └── myapp1.html
| └── myapp2
| └── myapp2.html
So, the key things which you need to do are just don't change(touch) the default settings of "TEMPLATES" in "settings.py" as shown below:
# "core/settings.py"
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",
],
},
},
]
Then, set "myapp1" and "myapp2" applicatons to "INSTALLED_APPS" in "core/settings.py" as shown below:
# "core/settings.py"
INSTALLED_APPS = [
...
"myapp1",
"myapp2",
]
Then, write each "views.py" of "myapp1" and "myapp2" applications as shown below. Be careful, you need to write each "templates" path "myapp1/myapp1.html" and "myapp2/myapp2.html" instead of just writing each "templates" path "myapp1.html" and "myapp2.html" in "render()" as shown below:
# "myapp1/views.py"
from django.shortcuts import render
def myapp1(request): # Don't write just "myapp1.html"
return render(request, "myapp1/myapp1.html")
# "myapp2/views.py"
from django.shortcuts import render
def myapp2(request): # Don't write just "myapp2.html"
return render(request, "myapp2/myapp2.html")
Then, set each "views.py" path of "myapp1" and "myapp2" applications as shown below:
# "myapp1/views.py"
from django.urls import include, path
from . import views
urlpatterns = [
path("", views.myapp1, name='myapp1'), # Here
]
# "myapp2/views.py"
from django.urls import include, path
from . import views
urlpatterns = [
path("", views.myapp2, name='myapp2'), # Here
]
Then, set each path to "urls.py" of "myapp1" and "myapp2" applications in "core/urls.py" as shown below. Finally, The templates of "myapp1" and "myapp2" applications will be read without any errors:
# "core/urls.py"
from django.urls import include, path
urlpatterns = [
...
path("myapp1/", include('myapp1.urls')), # Here
path("myapp2/", include('myapp2.urls')), # Here
]

Just a hunch, but check out this article on Django template loading. In particular, make sure you have django.template.loaders.app_directories.Loader in your TEMPLATE_LOADERS list.

Check permissions on templates and appname directories, either with ls -l or try doing an absolute path open() from django.

It works now after I tried
chown -R www-data:www-data /usr/lib/python2.5/site-packages/projectname/*
It's strange. I dont need to do this on the remote server to make it work.
Also, I have to run the following command on local machine to make all static files accessable but on remote server they are all "root:root".
chown -R www-data:www-data /var/www/projectname/*
Local machine runs on Ubuntu 8.04 desktop edition. Remote server is on Ubuntu 9.04 server edition.
Anybody knows why?

Make sure you've added your app to the project-name/app-namme/settings.py INSTALLED_APPS: .
INSTALLED_APPS = ['app-name.apps.AppNameConfig']
And on project-name/app-namme/settings.py TEMPLATES: .
'DIRS': [os.path.join(BASE_DIR, 'templates')],

I must use templates for a internal APP and it works for me:
'DIRS': [os.path.join(BASE_DIR + '/THE_APP_NAME', 'templates')],

See which folder django try to load template look at Template-loader postmortem in error page, for example, error will sothing like this:
Template-loader postmortem
Django tried loading these templates, in this order:
Using engine django:
django.template.loaders.filesystem.Loader: d:\projects\vcsrc\vcsrc\templates\base.html (Source does not exist)
In my error vcsrc\vcsrc\templates\base.html not in path.
Then change TEMPLATES in setting.py file to your templates path
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
# 'DIRS': [],
'DIRS': [os.path.join(BASE_DIR, 'vcsrc/templates')],
...

in your setting.py file replace DIRS in TEMPLATES array with this
'DIRS': []
to this
'DIRS': [os.path.join(BASE_DIR, 'templates')],
but 1 think u need to know is that
you have to make a folder with name templates and it should on the root path otherwise u have to change the DIRS value

add rest_framework to the INSTALLED_APPS if django rest framework. For my case I had missed adding it to the installed apps.
INSTALLED_APPS = [
'..........',,
'rest_framework',
'.........',
]

In my case it was enough just to include my application in INSTALLED_APPS in the settings.py file:
INSTALLED_APPS = [
"myapp",
"django.contrib.admin",
"django.contrib.auth",
"django.contrib.contenttypes",
"django.contrib.sessions",
"django.contrib.messages",
"django.contrib.staticfiles",
]
Also, remember that the template should be placed in your directory like so:
myapp/templates/myapp/template_name.html
but when you point at this template you do this like that:
template = loader.get_template("myapp/template_name.html")

django was configured to use templates in project_name/app_name/templates/app_name/template.html when referred with render(request, 'app_name/template.html', context)
If you got Template exception the reason is that you hadn't add app_name to installed_apps in settings.
I had the issue with django 4.1

Check that your templates.html are in /usr/lib/python2.5/site-packages/projectname/templates dir.

Hi guys I found a new solution. Actually it is defined in another template so instead of defining TEMPLATE_DIRS yourself, put your directory path name at their:

I'm embarrassed to admit this, but the problem for me was that a template had been specified as ….hml instead of ….html. Watch out!

I added this
TEMPLATE_DIRS = (
os.path.join(SETTINGS_PATH, 'templates'),
)
and it still showed the error, then I realized that in another project the templates was showing without adding that code in settings.py file so I checked that project and I realized that I didn't create a virtual environment in this project so I did
virtualenv env
and it worked, don't know why

I came up with this problem. Here is how I solved this:
Look at your settings.py, locate to TEMPLATES variable,
inside the TEMPLATES, add your templates path inside the DIRS list. For me, first I set my templates path as TEMPLATES_PATH = os.path.join(BASE_DIR,'templates'), then add TEMPLATES_PATH into DIRS list, 'DIRS':[TEMPLATES_PATH,].
Then restart the server, the TemplateDoesNotExist exception is gone.
That's it.

1.create a folder 'templates' in your 'app'(let say you named such your app)
and you can put the html file here.
But it s strongly recommended to create a folder with same name('app') in 'templates' folder and only then put htmls there. Into the 'app/templates/app' folder
2.now in 'app' 's urls.py put:
path('', views.index, name='index'), # in case of use default server index.html
3. in 'app' 's views.py put:
from django.shortcuts import render
def index(request): return
render(request,"app/index.html")
# name 'index' as you want

Works on Django 3
I found I believe good way, I have the base.html in root folder, and all other html files in App folders, I
settings.py
import os
# This settings are to allow store templates,static and media files in root folder
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATE_DIR = os.path.join(BASE_DIR,'templates')
STATIC_DIR = os.path.join(BASE_DIR,'static')
MEDIA_DIR = os.path.join(BASE_DIR,'media')
# This is default path from Django, must be added
#AFTER our BASE_DIR otherwise DB will be broken.
BASE_DIR = Path(__file__).resolve().parent.parent
# add your apps to Installed apps
INSTALLED_APPS = [
'main',
'weblogin',
..........
]
# Now add TEMPLATE_DIR to 'DIRS' where in TEMPLATES like bellow
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [TEMPLATE_DIR, BASE_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',
],
},

# On end of Settings.py put this refferences to Static and Media files
STATICFILES_DIRS = [STATIC_DIR,]
STATIC_URL = '/static/'
MEDIA_ROOT = [MEDIA_DIR,]
MEDIA_URL = '/media/'
If you have problem with Database, please check if you put the original BASE_DIR bellow the new BASE_DIR otherwise change
# Original
'NAME': BASE_DIR / 'db.sqlite3',
# to
'NAME': os.path.join(BASE_DIR,'db.sqlite3'),
Django now will be able to find the HTML and Static files both in the App folders and in Root folder without need of adding the name of App folder in front of the file.
Struture:
-DjangoProject
-static(css,JS ...)
-templates(base.html, ....)
-other django files like (manage.py, ....)
-App1
-templates(index1.html, other html files can extend now base.html too)
-other App1 files
-App2
-templates(index2.html, other html files can extend now base.html too)
-other App2 files

Simple solution
'DIRS': [BASE_DIR, 'templates'],

My problem was that I changed the name of my app. Not surprisingly, Visual Studio did not change the directory name containing the template. Manually correcting that solved the problem.

Another cause of the "template does not exist" error seems to be forgetting to add the app name in settings.py. I forgot to add it and that was the reason for the error in my case.
INSTALLED_APPS = [
'my_app',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]

in TEMPLATES :
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [r'C:\Users\islam\Desktop\html_project\django\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',
],
},
},
]
put the full directory of your templates file, then in views :
def home(request):
return render(request, "home\index.html")
start the path that after templates to the html file
in brief :
the full path is :
C:\Users\islam\Desktop\html_project\django\templates\home\index.html
C:\Users\islam\Desktop\html_project\django\templates
the full path to your template file will be in TEMPLATES in 'DIRS': [' ']
home\index.html the path that comes after template will be in render( )
