I was trying to add templates to my Django project but it returns an error: TemplateDoesNotExist at /

I get a mistake when tying to add templates to my Django project.
settings.py :
TEMPLATE_DIRS = (
os.path.join(os.path.dirname(__file__), 'templates'),
)
views.py:
def index(request):
a = models.User.objects.get()
return render(request, "main/list.html", {"list": a})
and list.html:
{% extends "base.html" %}
{% block title %}Chats{% endblock %}
{% block content %}
{% if list%}
{% for i in list%}
<h2>{{i.usrname}}</h2>
{% endif %}
The project folder itself looks like this:
Main folder is app.
Thanks for your help!

You should include the os.path.join(...) in the Template 'DIRS'
Example:
In settings.py
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, '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 in your folder structure, you should have
app_name (main app folder) --> templates --> app_name(again) --> templates go here.
EDIT: I forgot to mention that in order to do this you must import os

treid change TEMPLATE_DIRS completly with this
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',
],
},
},
]

How to make Django use current application's templates folder?

Right now I have a Django project with three apps. In my last app, the index.html loaded by my views.py is the index.html in another app's templates folder. Note this is how it is actually loading it, but not how I intend it load. The index.html in templates where the corresponding views.py is defined is not used. What I am wondering is how I define my settings so that the templates folder for the current application directory is used. This is my settings.py with respect to templates:
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',
],
},
},
]
This is the call to index.html
def indexView(request):
form = FriendForm()
friends = Friend.objects.all()
return render(request, "index1.html", {"form": form, "friends": friends})

A good practice is that from the inside of your urls.py from your app, you add :
app_name = 'your_app_name' # Now, you can call this app from the {% url tag %}
And your template structure should contain app directories, and when you want to render to a different template you can use :
return render(request, 'myApp1/index.html')
return render(request, 'myApp2/index.html')
But remember, in your main templates folder, you need to add 2 directories,
templates/myApp1/index.html,
and
templates/myApp2/index.html
And finally, did you added app_name to your apps URLs? And after that try with the first one, or with the full path.
{% url 'myApp1:post_friend' %} or full path {% url 'myApp1/index.html' %}

Using the template folder from another module in my django app

I am trying to use the postman module that is used for user to user messages in django and I have installed the app and set up the urls for it but whenever I click the link I get this error.
as far as I can tell the templates are there but django cant seem to find them. Could anyone tell me where I am going wrong?
Here's some of my code that might help too,
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav ">
<li>MyCourse</li>
<li>Timetable</li>
<li>logout</li>
<li>Messages</li>
</ul>
</div>
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'login/../login/../login/templates'), os.path.join('C:/Python27/Lib/site-packages/django-postman-3.3.1/postman/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',
],
},
},
]
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('login.urls')),
url(r'^messages/', include('postman.urls', namespace="postman")),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

The postman app comes with a postman/base.html template, which extends base.html. You are expected to create this base.html template, and include certain blocks in it.
See the docs for more info.

How can i change django admin to rtl style

First of all i'm new to django . and i'm amazing from this cool framework (not in database part and mysql connector)
And When i looking to django admin style folder in css folder ,
i see rtl css , but now i don't know how can i change admin style to rtl .
This is screen shot from my folders
Thank's

Try setting your language code in settings:
LANGUAGE_CODE = 'fa-ir'
for further reading on translating, rtl, changing date format and other localization things read this django doc.

Django looks at the TEMPLATES setting to find order to check for templates to render. As such, you can add rtl.css to the head of the base admin template in order to load the right-to-left css.
In a templates sub-directory of your main project directory, create dir admin and file base.html. Copy the contents of 'django/contrib/admin/templates/base.html' from Django's source to the newly created file.
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')], # <- add this line
'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',
],
},
},
]
In the template, you'll see {% block extra_head %}{% endblock %}. Insert the stylesheet link here, like this-
{% block extra_head %}
<link rel='stylesheet' href='{% static 'admin/css/rtl.css' %}' />
{% endblock %}
Now rtl.css will be loaded whenever any admin page is loaded.

Path to template directory not working in settings.py

Currently created a templates folder inside my project folder.
Then I added the admin folder and the file base_site.html to be able to change the Django admin title:
Home / Django / mysite / templates / admin / base_site.html
However, it doesn't change. My settings.py file 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',
],
},
},
]
Of Avinash Raj's request:
urls.py:
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
]
views.py:
from django.shortcuts import render

Since Django 1.7 you do not need to rewrite any templates to change admin title or header but just set site_header, site_title, and index_title in admin.py & then hook them in urls.py. Look here: https://stackoverflow.com/a/24983231/5253807
