Answer 1

You need to go to Heroku dashboard settings .

Then just enter all your environment variables like AWS_ACCESS_KEY_ID , AWS_S3_CUSTOM_DOMAIN , AWS_SECRET_ACCESS_KEY and etc....

Now, in settings.py

DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage'
AWS_ACCESS_KEY_ID = os.environ.get("AWS_ACCESS_KEY_ID", "") 
AWS_SECRET_ACCESS_KEY = os.environ.get("AWS_SECRET_ACCESS_KEY", "")
AWS_STORAGE_BUCKET_NAME = os.environ.get("AWS_STORAGE_BUCKET_NAME", "")
AWS_QUERYSTRING_AUTH = False 
AWS_S3_CUSTOM_DOMAIN = os.environ.get("AWS_S3_CUSTOM_DOMAIN", "")
MEDIA_ROOT = os.environ.get("MEDIA_URL", "")
MEDIA_URL = '/media/'

This should work fine then.

You can follow Amazon S3 bucket for storing media files of Django app on Heroku blog written by me for further understanding.
