TemplateDoesNotExist Error in django on a simple hello world project

I have a problem using templates in django. I believe I have the template in the right spot and after looking at the path from the error log, the file is there. I also have it working without using render(). But I have tried multiple things and in the error log it shows a path that I can follow to the html file that I am trying to render.
Here is the file structure of my project (Note: this file structure is actually inside C:\my_website)
Relevant code:
Below is my view from the hello app I created. How it is currently there is an error but if I comment out the render() call and use the uncommented code It displays the contents of index.html
C:\my_website\my_website\hello\views
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
import os
import logging #MS ADDED
logger = logging.getLogger(__name__)#MS ADDED
def index(request):
#!!! It works with this stuff uncommented
#index_path = os.path.join(os.path.dirname(os.path.dirname(__file__)),'hello\\templates\\hello\\index.html')
#logger.error('Views - index_path is ' + index_path) # MS ADDED
#with open(index_path) as f:
# html_string = f.read()
#return HttpResponse(html_string)
return render(request, 'hello/index.hmtl')
Below is everything that I have changed in the settings. I read in the Django docs that if you didnt specify a path it would look in a templates directory in the app you create (hello). But leaving DIRS empty in TEMPLATES did gave a TemplateDoesNotExist exception. So I tried a few other things that did not work shown below.
C:\my_website\my_website\my_website\settings
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'hello.apps.HelloConfig',
]
SETTINGS_PATH = os.path.dirname(os.path.dirname(__file__))#MS ADDED
Temp_Path = os.path.realpath('.')# MS ADDED
index_path = os.path.join(os.path.dirname(os.path.dirname(__file__)),'hello/templates')#MS ADDED
#MS Note: I tried for DIRS below os.path.join(SETTINGS_PATH,'templates')
#MS Note: I tried for DIRS below Temp_Path + "hello/templates"
#MS Note: I tried for DIRS Below os.path.join(os.path.dirname(os.path.dirname(__file__)),'hello/templates')

Template loader postmortem
Django tried loading these templates, in this order:
Using engine django:

In the error log it says this
C:\my_website\my_website\hello\templates\hello\index.hmtl (Source does not exist)
But it does exist and it contains just
<h1>Hello World! aafa</h1>
With the commented out code in the view, the app displays:
I am using django version 3.1.2 and python version 3.8.6
any help would be greatly appreciated

In the render function you're passing "index.hmtl" instead of "index.html"

TypeError at /registration/login/ sequence item 0: expected string or Unicode, function found in Django 1.11

I am modifying Gitstack, a 32bit Python2.7-based Git Web Application (available here) for my 64bit Python installation.
In the process, I also had to modify all the Django codes e.g. urlpatterns, etc.
While I managed to adapt it to my Apache/PHP environment, I ended up with this Django issue.
The error is as below while trying to access /gitstack location

I could not make any useful insight from the traceback below with my little head. The traceback just ends inside Django which seems very little helpful.

Below is my modified app\urls.py:

url(r'^gitstack/', include('gitstack.urls')),
# url(r'^rest/', include('rest.urls')),
]
Here is my modified gitstack/urls.py
from django.conf.urls import url, include
from .views import index, users, groups, repository_permission, add_repo_user_dialog, add_repo_group_dialog, group_user, add_group_user_dialog, settings_general, settings_authentication, settings_security, log_me_out
urlpatterns = [
# standard user interface
url(r'^$', index, name='index'),
url(r'^users/', users, name='users'),
url(r'^groups/', groups, name='groups'),
url(r'^repository/(?P<repo_name>.+)/permission/$', repository_permission, name='repository_permission'),
# add users dialog
url(r'^repository/(?P<repo_name>.+)/permission/adduser/$', add_repo_user_dialog, name= 'add_repo_user_dialog'),
url(r'^repository/(?P<repo_name>.+)/permission/addgroup/$', add_repo_group_dialog, name='add_repo_group_dialog'),

url(r'^settings/general/', settings_general, name='settings_general'),
url(r'^settings/authentication/', settings_authentication, name='settings_authentication'),
url(r'^settings/security/', settings_security, name='settings_security'),
url(r'^logout/', log_me_out, name='log_me_out'),
]

urlpatterns should be a Python list of url() instances. So you need to remove 'gitstack.views', from urlpatterns in gitstack/urls.py
UPD
Also you have problem with login pattern. Name should be string. Change url(r'^registration/login/$', login, name=login) to url(r'^registration/login/$', login, name='login')

I have a problem with django-comments-xtd when I try to work with django 1.9. I'm following this tutorial. When I work with Django 1.8 everything is fine. But if I use Django 1.9 I get the error when I send a message.

In theory django-comments-xtd is compatible with django 1.9
I've got the same issue when I work with my own project (dj 1.9). And even when I run the example (dj 1.9) for tutorial. Everything is fine until I send a message.
Here is forms.py of my own app.

I guess that link can help you. I have the same error and it disappeared when I added **kwargs to custom get_comment_create_data() method, as claudep said.

I just did few modifications on the text of /domiciliaciones.html processed the .po translation files and overwritted the translation files and the .html
I tried to fix the page returning to the original (without my changes) but it doesn't work neither.
If someone could help it would be great, I'm kind of desperate to fix that.
I don't know if you need more information about the app, just let me know!
Many thanks in advance!

Maybe I can answer your question! In Django 1.8.2, Deprecated since version 1.8: Set the DIRS option of a DjangoTemplates backend instead.,so,you should not set TEMPLATE_DIRS,In my opintion,you should set
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': ['templates'],
'APP_DIRS': True,
}
]
I spent a half of day to solve this problem in my WebApp! I guess this will help you!

template not found for Django homepage

I'm still new to Django and I am trying to create a small website as practice. However I am currently running into this error. If someone could explain where I went wrong and teach me how I can fix this that would be great! I'm new and the Documentation can be hard to read sometimes =[
Please let me know if there is anything else I need to add!

Please do not include the full path in settings as the accepted answer suggests. This is the "anti-django" way of doing things, even if it does work.
In Django you can either have one templates folder for a project or one templates folder per app. The latter allows you to move apps from project to project (which is how they are supposed to work) but the former can provide simplicity for monolithic once-off projects.
You DO NOT need to and should not specify the absolute path. In your settings, if you want a single templates directory for your project use something like:
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATE_DIRS = (
os.path.join(BASE_DIR, 'templates')
,)
This is basically saying your templates are in a folder called 'templates' that is in the main BASE_DIR path. In this example that would be the root directory where the manage.py resides. Now just make a folder called 'templates' in this root directory and throw your HTML in there (arranged in subfolders if you like).
Templates can then be loaded as simply as
templt = get_template('mytemplate.html)
Where it is presumed that mytemplate.html file resides directly in the templates/ folder off the root directory. You can use subfolders and if you do you should specify them in the quotes e.g. 'mysubdir/mytemplate.html'
As an alternative, you can allow each app to have its own templates
In this case you must have the following in settings:
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',
],
},
},
]
The key here is
'APP_DIRS': True,
This (according to the Django docs) instructs the system to look in each app for a 'templates' folder. Your project would then look something like (presuming a project name of mybigproject)
/home/myaccount/mybigproject/myapp1/templates/
and
/home/myaccount/mybigproject/myapp2/templates/
By contrast in the first scenario (single templates folder) it would just be
/home/myaccount/mybigproject/templates/
However the important thing to take away is that you STILL REFERENCE IT AS:
templt = get_template('mytemplate.html)
Django will search through all the app folders for you.
If it still gives you a file not found error it is a configuration thing.
If you specify a full path, now you need to change that path as you move PC's (e.g. shared projects), projects or apps which is a disaster.

In your settings.py file you should use below code.
#settings.py
import os
# Full filesystem path to the project.
PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))
TEMPLATE_DIRS = (os.path.join(PROJECT_ROOT, "templates"),)

You don't show the value of your TEMPLATE_DIRS setting. But looking at the error message, it looks like you're using ~/... there. Don't do that: use the full path - /home/bradford/Development/Django/pub_pic/templates.
