# Deploy Django App to Heroku

```sh 
pip install dj-database-url gunicorn whitenoise
```
```
sh pip freeze > requirements.txt
``` 
+ add `psycopg2==2.6.2` at the end in `requirements.txt`)
+ Create Procfile file for Heroku and add: 
 ```sh
 web: gunicorn mysite.wsgi 
 ```
+ Create runtime.txt then add python version which you are using (python-3.5.2) make sure `p` is not in Caps.
+ Create `local_settings.py` inside your main app, suppose you have main dir. named `maiProject` then you will have same dir. inside with same name along with `setting.py` file. Add following code.
```sh
import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}
DEBUG = True
```
+ Add following code inside `settings.py` file
 ```sh
import dj_database_url
DATABASES['default'] = dj_database_url.config()
SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')
ALLOWED_HOSTS = ['*']
DEBUG = False
try:
    from .local_settings import *
except ImportError:
    pass
 ```
 + Add code inside `wsgi.py`
  ```sh
from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(application)
  ```
