Update production.py with:

• first install the following packages in command promt

pip install psycopg2

change BASE_DIR to

BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))

import dj_database_url
db_from_env = dj_database_url.config()
DATABASES['default'].update(db_from_env)
DATABASES['default']['CONN_MAX_AGE'] = 500

MEDIA_URL = "/media/"
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

STATIC_URL = "/static/"
STATICFILES_DIRS = [os.path.join(BASE_DIR, "staticfiles")]
STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static-cdn-local")


CORS_REPLACE_HTTPS_REFERER      = True
HOST_SCHEME                     = "https://"
SECURE_PROXY_SSL_HEADER         = ('HTTP_X_FORWARDED_PROTO', 'https')
SECURE_SSL_REDIRECT             = True
SESSION_COOKIE_SECURE           = True
CSRF_COOKIE_SECURE              = True
SECURE_HSTS_INCLUDE_SUBDOMAINS  = True
SECURE_HSTS_SECONDS             = 1000000
SECURE_FRAME_DENY               = True

• run the following in terminal and replace with your secret key WITHOUT the quotes

heroku config:set SECRET_KEY=<your-django-secret-key>

then IN production.py replace SECRET_KEY = "XXXXXXXXXXXXXXXXXXX" with

SECRET_KEY = os.environ.get('SECRET_KEY')

local.py Updates:

• change BASE_DIR to

BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))

and also update the following

MEDIA_URL = "/media/"
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

STATIC_URL = "/static/"
STATICFILES_DIRS = [os.path.join(BASE_DIR, "staticfiles")]
STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static-cdn-local")


CORS_REPLACE_HTTPS_REFERER      = False
HOST_SCHEME                     = "http://"
SECURE_PROXY_SSL_HEADER         = None
SECURE_SSL_REDIRECT             = False
SESSION_COOKIE_SECURE           = False
CSRF_COOKIE_SECURE              = False
SECURE_HSTS_SECONDS             = None
SECURE_HSTS_INCLUDE_SUBDOMAINS  = False
SECURE_FRAME_DENY               = False

S3 Settings

• These are the settings we will use in S3 console

NB remember to replace <your_bucket_name> with your bucken name

• first install the following packages in command promt

pip install boto boto3 django-storages

• Update INSTALLED_APPS in production.py:

INSTALLED_APPS = [
   
    'storages',
    
]

• Create aws module in same directory as settings module:

inside the aws folder(which has a blank init.py file, create utils.py and conf.py files

-In utils.py add the following:

from storages.backends.s3boto3 import S3Boto3Storage

StaticRootS3BotoStorage = lambda: S3Boto3Storage(location='static')
MediaRootS3BotoStorage  = lambda: S3Boto3Storage(location='media')

• In your conf.py add the following:

NB: the AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY are gotten after we create a use in IAM

Make sure that S3DIRECT_REGION is correct and you've replaced AWS_STORAGE_BUCKET_NAME with your bucket name

import datetime
AWS_ACCESS_KEY_ID = "<your_access_key_id>"
AWS_SECRET_ACCESS_KEY = "<your_secret_access_key>"
AWS_FILE_EXPIRE = 200
AWS_PRELOAD_METADATA = True
AWS_QUERYSTRING_AUTH = True

DEFAULT_FILE_STORAGE = '<your-project>.aws.utils.MediaRootS3BotoStorage'
STATICFILES_STORAGE = '<your-project>.aws.utils.StaticRootS3BotoStorage'
AWS_STORAGE_BUCKET_NAME = '<your_bucket_name>'
S3DIRECT_REGION = 'eu-west-2'
S3_URL = '//%s.s3.amazonaws.com/' % AWS_STORAGE_BUCKET_NAME
MEDIA_URL = '//%s.s3.amazonaws.com/media/' % AWS_STORAGE_BUCKET_NAME
MEDIA_ROOT = MEDIA_URL
STATIC_URL = S3_URL + 'static/'
ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/'

two_months = datetime.timedelta(days=61)
date_two_months_later = datetime.date.today() + two_months
expires = date_two_months_later.strftime("%A, %d %B %Y 20:00:00 GMT")

AWS_HEADERS = { 
    'Expires': expires,
    'Cache-Control': 'max-age=%d' % (int(two_months.total_seconds()), ),
}

• then in your production.py file add this

from <your-project>.aws.conf import *

I really appreciate this lesson, nice work

nice work
