TemplateDoesNotExist in Django views

I'm new to Django, currently following the tutorial on the Django site for polls:
https://docs.djangoproject.com/en/4.1/intro/tutorial03/
I'm not able to render my template when using polls/index.html. I have followed along verbatim, yet when i try to render the request in the views.py file, I am getting a TemplateDoesNotExist error, which states that the source is not found. What I don't understand is my index.html is located in the correct location (IE, mysite > polls > template > polls > index.html) and my main settings are exactly how the tutorial states. I've tried the frequently suggested (if dated) response of adding os.path.join(SETTINGS_PATH, 'templates'), however the issue persists.
I'm currently running Python 3.10 with Django 4.1, yet this shouldn't be the problem. I've confirmed that my index.html file is in the correct location, being stored in templates > polls > index.html.

Here is my directory structure (note that index.html resides in the proper subdirectory, 'polls'):

You have named the folder wrong. It should be plural - templates, not template.

TemplateDoesNotExist at /accounts/ (Django With Flutter)

I am trying to connect Flutter with Django. Flutter and Django alone seems to be fine,working without error. But when i am trying to combine both together, an error pops up that says:
TemplateDoesNotExist at /accounts/
Here is the cause of the problem
from django.shortcuts import render, HttpResponse
def home(request):
return render(request, '../screens/login_screen.dart')
It says that directory does not exists.
As you see above the directory exists. What is the problem can somebody help?
Template:
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',
],
},
},
]

What I can see is that the screens folder is on the root but not inside the accounts folder it's self.
For that you have to explicitly mention in the templates configurations within settings. You have to mention the "BASE_DIR, 'name of the folder where the templates are'". Here how it has to be written.
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR,'screens')],
'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',
],
},
},
]
Secondly, you have to give the path of the file within in the views in such manner.
return render(request, 'screens/login_screen.dart', context)
Hope that helps.

Django template Module Import Error

Using Django version 1.9.5 and Python 3.
Upon navigation to the url, I am getting the following error:
ImportError at /music/
No module named 'django.templates'
Request Method: GET
Request URL: http://localhost:8000/music/

Exception Type: ImportError
Exception Value:

'D:\\Program Files (x86)\\Python\\lib',
'D:\\Program Files (x86)\\Python',
'D:\\Program Files (x86)\\Python\\lib\\site-packages']
The error seems to be coming from the import line. Checked syntax and tried to explicitly provided the path under TEMPLATES at DIRS but same result. Anyone encountered a similar issue? Found some similar issues raised but in different languages.
Folder Structure for template: name_of_app/templates/inner_folder/html_file
music/templates/music/index.html
views.py
from django.http import HttpResponse
from django.template import loader # error gone if i remove this line
from .models import Album
def index(request):
all_albums = Album.objects.all()
template = loader.get_template('music/index.html')
context = {
'all_albums': all_albums
}
return HttpResponse('test test')
settings.py
TEMPLATES = [
{
'BACKEND': 'django.templates.backends.django.DjangoTemplates',
'DIRS': [],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.templates.context_processors.debug',
'django.templates.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]

This looks like the programmer's greatest nemesis: a typo. You can see midway in the 2nd code snippet a reference to django.templates..., but your 2nd line is importing from django.template.
Edit: From my testing, an incorrect import will fail in the shell, and an incorrect reference in context_processors will fail in the browser.

TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.contrib.auth.context_processors.auth',
'django.template.context_processors.debug',
'django.template.context_processors.i18n',
'django.template.context_processors.media',
'django.template.context_processors.static',
'django.template.context_processors.tz',
'django.contrib.messages.context_processors.messages',
],
},
},
]

Try to use this method to render your template using module django.shortcurt.render():
from django.shortcuts import render
from .models import Album
def index(request):
all_albums = Album.objects.all()
context = {
'all_albums': all_albums
}
return render(request, 'music/index.html',context=context)

Django Developments Template_DIRS setting failed

I was recently trying to learn Django for one of my private project.
When came to the Chapter on Template,the Django Book recommended setting template path in settings.py using the the following snippet
TEMPLATE_DIRS = (os.path.join(os.path.dirname(__file__),'templates').replace('\\','/'),)
However ,when I opened the file setting.py I found nothing like "TEMPLATE_DIR" but a list:
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(os.path.dirname(__file__), 'templates').replace('\\','/'),],
'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 the value related to the key "DIR",was a empty list. So I try to filled it with the content shown above.
And then, code something in the views.py(all the import was done )
def current_datetime(request):
now = datetime.datetime.now()
t = get_template("current_datetime.html")
html = t.render(Context({"current_date" : now}))
return HttpResponse(html)
And then mkdir templates in the same folder with setting.py , saved current_datetime.html in folder templates
Finally,run the project.and got the message in my terminal:
WARNINGS:
?: (1_8.W001) The standalone TEMPLATE_* settings were deprecated in Django 1.8 > and the TEMPLATES dictionary takes precedence. You must put the values of the > following settings into your default TEMPLATES dict: TEMPLATE_DIRS.

Django version 1.11.2, using settings 'mysite.settings'
Starting development server at 127.0.0.1:8000/
Quit the server with CONTROL-C.
When opened the address (127.0.0.1:8000/time/) in my Safari,here came the
error message:
enter image description here
Anyone help,please ??

There is a warning on TEMPLATE_DIRS, for that just be sure you don't have TEMPLATE_DIRS variable in your settings.py and restart development server.
Then for the error, you are actually using a Context object instead of a dict, you should render the template using a useful shortcut https://docs.djangoproject.com/en/1.11/topics/http/shortcuts/#example
from django.shortcuts import render
def current_datetime(request):
now = datetime.datetime.now()
return render(request, "current_datetime.html", {
'current_date' : now,
})

I think you have BASE_DIR in settings.py for define location so use like below
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',
],
},
},
DIRS should be like below
'DIRS': [os.path.join(BASE_DIR, 'templates'),],

How to integrate django-rest-swagger 2.0 with existing DRF application(Beginner)

I am trying to integrate swagger 2.0 with existing DRF application but it gives following error in browser after runningpython manage.py runserver:
TemplateDoesNotExist at /swagger rest_framework_swagger/index.html
Request Method: GET Request URL: http://127.0.0.1:8000/swagger
Django Version: 1.10 Exception Type: TemplateDoesNotExist Exception
Value: rest_framework_swagger/index.html Exception
Location: C:\Users\MHAZIQ~1\Desktop\Tkxel\mmg-git\venv\lib\site-packages\django\template\loader.py
in get_template, line 25
I have added following lines in
views.py:
from rest_framework_swagger.views import get_swagger_view
schema_view = get_swagger_view(title='Pastebin API')
And I have added following lines in
urls.py:
url(r'^swagger', views.schema_view),
I ve tried applying following solution:
TemplateDoesNotExist at /docs/ rest_framework_swagger/index.html
but it didnot solve my problem, Can anyone please help me in this regard?

Add 'rest_framework_swagger' to INSTALLED_APPS in Django settings.
settings.py
INSTALLED_APPS = [
...
'rest_framework_swagger',
]
https://django-rest-swagger.readthedocs.io/en/latest/

After several hours of research I have found the problem with my code, as I was adding swagger into an existing project, it didnt have following parameters in 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',
],
},
},]
Now swagger works absolutely fine!
