Static file image in not found - django

Question

I am very new to Django and trying to do some static file exercise.
Under the project Twenty3rdMarch I have created a folder static and under that one folder called images. In the images folder, I have placed a few images.
Here is my setting.py:
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)
STATIC_DIR=os.path.join(BASE_DIR,'static')
SECRET_KEY = 'mz^^exko#!2czk35u$w-qr&v8u(46(fp7#u41ctabvwf=mz9m&'
DEBUG = True
ALLOWED_HOSTS = []
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'first_app',
]
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
ROOT_URLCONF = 'Twenty3rdMrach.urls'
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [TEMPLATES_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',
],
},
},
]
WSGI_APPLICATION = 'Twenty3rdMrach.wsgi.application'
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'udemy',
'USER':'root',
'PASSWORD':'Ravi#go123',
'HOST':'localhost',
'PORT':'3306',
}
}
AUTH_PASSWORD_VALIDATORS = [
{
'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
},
]
LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True
STATIC_URL = '/static/'
STATICFILES_DIR=(STATIC_DIR,)
Here is my view:
from django.shortcuts import render
from django.http import HttpResponse
from django.template import loader
def index(request):
template=loader.get_template('first_app/index.html')
my_dict={'insert_me':"Hello I have created my first dynamic Template"}
return HttpResponse(template.render(my_dict,request))
def help(request):
template=loader.get_template('first_app/help.html')
context1={'help':'Helping Hand!!'}
return HttpResponse(template.render(context1,request))
Here is my Twenty3rdMarch\url.py:
from django.contrib import admin
from django.conf.urls import url
from django.conf.urls import include
from first_app import views
urlpatterns = [
url(r'', views.index, name='index'),
url(r'^first_app/',include('first_app.urls')),
url(r'^help/',include('first_app.urls')),
url(r'admin/', admin.site.urls)
]
Here is my first_app\url.py:
from django.conf.urls import url
from first_app import views
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
from django.conf.urls.static import static
urlpatterns= [
url(r'', views.index, name='index'),
url(r'help/',views.help,name='help'),]
urlpatterns+=staticfiles_urlpatterns()
whenever I am hitting the URL http://127.0.0.1:8000/static/images/dj.jpg it's throwing 404 error.
