python - Serve static files on heroku using AWS S3 for django?

Question

i'm deploying a django application using heroku and AWS S3 for static files, the problem is that i haven't found information on how to link the Postgres DB of heroku with the S3 service.

I've already set the AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, S3_BUCKET, Add CORS Configuration, but my question is how can i link the S3 storage with the postgres DB of Heroku? Is this possible?

This is how my model looks in the admin, but if i upload the images here, after 5 minutes disappears. Image Upload for the model http://ishopss.com/imageUpload.png

Of course i can use static urls like this, but the problem is that i want to display different images for very course, not the same image for all. serve in the db http://ishopss.com/for.png

So my code needs to be like this, to serve different images aws static file http://ishopss.com/course.png

I hope some one could help me, Thanks.

I found the solution in this posts:

https://devcenter.heroku.com/articles/s3

Basically i need to download boto (pip install boto) and put it in requirements.txt(pip freeze > requirements.txt), and in settings.py add:

INSTALLED_APPS = ('storages',)

AWS_ACCESS_KEY_ID = 'xxxxxx'
AWS_SECRET_ACCESS_KEY = 'xxxxxxx'
AWS_STORAGE_BUCKET_NAME = 'bucket_name'


STATICFILES_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'

STATIC_URL = 'http://s3.amazonaws.com/%s' % AWS_STORAGE_BUCKET_NAME + '/'

Then you need to set 'AWS_ACCESS_KEY_ID', 'AWS_SECRET_ACCESS_KEY', 'AWS_STORAGE_BUCKET_NAME'

using

$ heroku config:set AWS_ACCESS_KEY_ID=xxx AWS_SECRET_ACCESS_KEY=yyy
$ heroku config:set S3_BUCKET_NAME=appname-assets

Update the src and href in your html:

url http://ishopss.com/url.png

Finally you need to update the permissions in https://console.aws.amazon.com/
