I am very new to Django. I am facing an exception TemplateDoesNotExist at /. I guess there is some problem with my template DIR.

Here is the URL:

from django.conf.urls import url
from first_app import views

urlpatterns= [
    url(r'', views.index, name='index'),
]

Here is the view:

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)

Here is my Settings:

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)
ALLOWED_HOSTS = []

Change Twenty3rdMarch/first_app/templates/index.html to index.html. You don't need full path when referencing templates from APP_DIRS.

However I suggests you to namespace your templates dirs properly. Simply putting index.html in app's template dir can cause template overriding. You should create directory inside app's template dir with same name like this.

myapp
  templates
    myapp
      index.html

and then reference it like myapp/index.html

For more information, please read this doc.

You can create the templates folder under your main project's folder and make this change to your settings.py 

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