I just installed a carrier wave and installed the rails 4 app for storing images on Amazon s3 through fog. The application worked and was deployed to Heroku with Carrierwave (but images were cleared using dyno). After some initial problems, I started working on my local host (as far as I could tell).
Now I am having trouble pushing the new version on Heroku. I have a reset DATABASES. Precompiled assets and now trying to perform database migration. Below is the error I am getting.
Running `rake db:migrate` attached to terminal... up, run.6517
rake aborted!
