Deploy ready Django application on Heroku servers

I have already developed an application with Python Django and it's working, I am new to Python Django and now I need to deploy it on heroku servers, there are so many blogs and websites including heroku site that explains deploying a django app on heroku from scratch I haven't found any which talks about a running app

for example all of them need installing django which makes me confused,

this is the folder structure of my app:

 myapp
 |_my_app
 | |_Settingd.py
 | |_urls.py
 | |_wsgi.py
 |__webapp
    |_statics(folder) 
    |_admin.py
    |_models.py
    |_views.py

The app is connecting to mysql server locally

Question(s):

Now I am totally confused, how do I have to deploy my running app on heroku? among the steps to deploy an app on heroku provided below which ones are mandatory for me and which ones I can escape and according to my folder structure where should be the location of requirements.txt or Procfile and what should be the content of them?

https://devcenter.heroku.com/articles/getting-started-with-django

Do I have to install virtualenv? and yes where should I run this command(in which folder) I think I don't have to install django or any database api or driver for django? since they are all already installed

So the first question of yours is why the app should be running inside Virtualenv?

what's the first step? Install Django, right? Not quite. One common problem with installing packages directly to your current site-packages area is that, if you have more than one project or use Python on your machine for things other than Django, you may run into dependency issues between your applications and the installed packages. For this reason, we'll be using virtualenv to manage our Django installation. This is common, and recommended, practice among Python and Django users.

Then install and activate your virtualenv using this command...

$ virtualenv env

$ source env/bin/activate

And finally we activated the environment. Now it'll look like this

(env)rs@rajasimon-desktop:~/studio/Project$

Then i guess your second doubt what is the purpose to install django-toolbelt ?

If you are installing django-toolbelt it will install all the dependencies or package need.

it contains Django, psycopg2, gunicorn, dj-database-url, dj-static, static

Firstly Heroku natively uses postgres. Life will be easier for you if you use that locally.

If you really want to use mysql, you have two paths to follow.

1) Run mysql locally, but convert to postgres when migrating to Heroku using the mysql2psql gem, as described here: https://devcenter.heroku.com/articles/heroku-mysql

2) Use a mysql addon like https://addons.heroku.com/cleardb

However my recommendation would be to use postgres end to end, as it is baked into Heroku, and you'll be working with the default ways of using Heroku, not against the

This is my project package i am currenlty working 

(env)ri@rajasimon-desktop:~/studio/project$ pip freeze
Django==1.6.5
MySQL-python==1.2.5
Pillow==2.5.3
argparse==1.2.1
django-ckeditor-updated==4.2.8
wsgiref==0.1.2

where should be the location of requirements.txt & Procfile ?

How to make requirements.txt file ?

By running below command will automatically include all packages inside txt file.

pip freeze > requirements.txt

Declare process type with Procfile

The procfile is for starting the dyno when in productioin. I always right like this..

web: gunicorn project.wsgi

So finally your project structure will look like this

myapp
 |_my_app
 | |_Settingd.py
 | |_urls.py
 | |_wsgi.py
 |__webapp
 |   |_statics(folder) 
 |   |_admin.py
 |   |_models.py
 |   |_views.py
 |__manage.py
 |__requirements.txt
 |__Procfile
