Trouble with Heroku Deployment and Interpreting Heroku Log

Question

This is my last resort to figure this out. I've searched through stackoverflow and googled various topics, but it seems to come down to how to interpret/analyze my own Heroku log. There's so much going on that I'm not sure where to look first. I see things like eager_load and direction to files app/config/environment:rb:5 and there also seems to be issues with my Unicorn configurations and relationship associations. I've gone through my files and haven't been able to locate what my logs are referring to, up until now it's been really easy to interpret errors.

A little background: I had originally built my rails app with the default Sqlite3 settings and I have attempted to switch it to Postgres. So maybe there's some conflicts with that going on as well. I want to be able to read my Heroku Logs in the future on my own and know exactly where to look. So if someone could provide a good tutorial about reading Heroku Logs that would be great as well.

Here's where I've looked so far: I've looked on devcenter on heroku's website, but I'm not making the connection from their instructions, to the issue in my code. I'm just a that stuck point, but have been trying to figure it out for days! I'm worried that I'm just missing something basic, which is why I haven't been able to figure this out yet.

I've also looked at association_basics.html on ruby on rails guides because I've been having some syntax issues.

I've used foreman start to see if my Procfile is working and have gotten another huge list. I've also used heroku ps, which gives me web.1 crashed

Here's the Heroku Log that's also connected to my app's github page: https://github.com/jsmit032/seasons-app/issues/29

If any other information is required, please let me know and I'll edit my questions so hopefully this can help others as well.

Answer 1

So I got the whole app to deploy! Turns out it was a pre-complied issue.

So I went through the guide on Heroku for pre-compiling assets in Rails 4: https://devcenter.heroku.com/articles/rails-4-asset-pipeline

I also went through the heroku guide for prepping your rails 4 app: https://devcenter.heroku.com/articles/getting-started-with-rails4#migrate-your-database

Also went through the heroku guide for SQLite on Heroku and the Deploying Rails Applications with Unicorn guide.

Looking through the console errors on the actual site was a huge help. It's how we figured out that the assets pipeline might not be working.

Answer 2

2014-11-21T19:27:58.271705+00:00 app[web.1]: has_many :user, through :user_to_destinations

doesn't look right - it should be

has_many :user, through: :user_to_destinations

at /app/app/models/destination.rb:3
