Heroku not authenticating; deploying heroku server issues; what's happening? - ruby-on-rails

Question

I am having serious problems getting Heroku and github to work with me.
I notice that I do not get an authentication from Heroku once I put in my log in information:
heroku login
Enter your Heroku credentials.
Email: blank#gmail.com
Password (typing will be hidden):
Logged in as blank#gmail.com
I do not get an authentication message, something my instructor said was very important. I have no idea why. I have everything set up correctly, including the proper ssh key, which I got via:
heroku keys:add
Then
heroku create
This is where things start really going wrong. I never get
Git remote heroku added
Instead, I just get
Creating app... done, stack is cedar-14
https://agile-lake-38079.herokuapp.com/ | https://git.heroku.com/agilelake-38079.git
With no indication of anything added.
After
git push origin master
and
git push heroku master
I get this same error every single time:
'Counting objects: 66, done.

Compressing objects: 100% (55/55), done.

I have tried altering the application.rb file, just in case, and I have also tweaked my Gemfile to make sure it has:
group :production do
gem 'pg'
gem 'rails_12factor'
end
Neither have worked. Thanks to anyone who can help.

Your authentication is fine :)
When you push to Heroku, it creates a slug of your application — think of it like a compressed, production-ready and production-tuned package.
Your problem lies when Heroku tries to create this slug. Your log outputs this line:
remote: NoMethodError: undefined method `raise_in_transactional_callbacks=' for ActiveRecord::Base:Class
Models inherit from ActiveRecord::Base, so that should tell you that it's something (very likely) in your model code.
Locally, you can run rake assets:precompile RAILS_ENV=production to see how Heroku would treat app.
