I often find People find hard when it comes to manual deployment but we must always deploy manually as its good practice to do that, It's just like using git bash/shell for commands instead of using Github Desktop as its talking to computer in his language and most importantly learning out about logs and errors in that. Read Further....

Prerequisites:-

A system loaded with any OS for a test Django App for deployment, A GitHub Account, A Heroku account.

Step by step guide for deployment of django APP on heroku

step1 :

Create Procfile often get error just replace P with lowercase p.

Note: as in my case happend it.

Replace with your project name

web: gunicorn You_ProjectName.wsgi --log-file -

step2 :

Install gunicorn

pip install gunicorn

step3 :

Prepare a requirements.txt okkkk...Now You want to tell server what you have & it must dowload for you. This file in your project is used to tell the server what dependencies.

pip freeze > requirements.txt

and Update settings.py file Set the following changes.

DEBUG = False

ALLOWED_HOSTS = ['127.0.0.1','sampledomain.com']

step4 : Update

Original Middle ware Code

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',
]

Updated Middle ware Code

Install whitenoise dependency

pip install whitenoise

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    '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',
]

step3 : Update

Original urls.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include("Home.urls")),
]

Updated urls.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include("Home.urls")),

    url(r'^media/(?P<path>.*)$', serve,{'document_root':       settings.MEDIA_ROOT}), 
    url(r'^static/(?P<path>.*)$', serve,{'document_root': settings.STATIC_ROOT}), 
]

Also don't Forget to

from django.views.static import serve
from django.conf.urls import url

You have done most of the part just open heroku account do following: Importantanly commit all changes to github.

By clicking on “New” you can open the Create New App. -> Now switch to deploy panel -> Connect to github and select Repo -> Click “Deploy” under “Manual Deploy”
