Rails 4 on Heroku with 'protected_attributes' gem - ruby-on-rails

Question

I don't know where else to turn with this: I have spent many hours on my project, a recruiting events website for college students, but have reached quite the impasse.
In short, I plodded along in localhost - adding components like Devise; Omniauth authentication via providers Facebook, LinkedIn, and Google - building a website I was proud of along the way. Everything appeared to be working just fine, but once I pushed to 'heroku master' things started breaking big time.
I think the issues are most likely in or around:I have an Authentication model to keep track of a single user's authentication providers, alongside the User model (where all the oauth code is kept).
Without further ado, here is my app's heroku domain and my code:
http://lit-everglades-7633.herokuapp.com/
https://gist.github.com/mecampbellsoup/6357855
The things breaking which I suspect are related:
'heroku run rake db:seed' following 'pg:reset' & 'rake db:migrate'... instead of seeding with the contents of the seed file itself, a single blank Event and Company are created; more on this below
the routing and action relating to the omniauth request seems to be working just fine, according to the heroku logs (below) but no user nor authentication is actually created:
when, after resetting postgres db, I try to run 'heroku run rake db:create' or 'db:setup' I am whined at as follows:
☁ duke_recruits [master] heroku run rake db:setup
Running rake db:setup attached to terminal... up, run.5886
FATAL: permission denied for database "postgres"
DETAIL: User does not have CONNECT privilege.
also, 'heroku run rake db:seed' appears to be doing its thing, but then my db only has 1 empty Event and 1 empty Company:
☁ duke_recruits [master] heroku run rake db:seed
Running rake db:seed attached to terminal... up, run.1767
☁ duke_recruits [master] heroku run rails c
Running rails c attached to terminal... up, run.6135

Please let me know what questions you have for me and if I can clarify anything at all. I really appreciate your time & help SO!

Answer 1

After a pg:reset, you can run the create command, but it usually gives you output like:
slkdjfs0dslkd already exists
So then you'll know that your database is created and ready to be used. Before you can seed though make sure you migrate. Just the standard heroku way
heroku run rake db:migrate
Then seed as normal
heroku run rake db:seed
