Question

I\'m having a problem deploying my Rails app to Heroku, where this error is thrown when trying to access the app:

PGError: ERROR: relation \"organiz

Answer 1

Are you using devise? I had this exact issue when upgrading to 2.0 - You have to manually change the migration file.

Answer 2

According to my experience (Rails 3.1, Sedar stack) after running pg:reset and db:migrate you might have to run heroku restart.

Answer 3

In my case, I also had to destroy and recreate my app. I had run a rake db:migrate with a migration file not committed and for whatever reason, the pg:reset wasn't working.

Answer 4

There may be many reasons for this error. For my app, however, the issue was that I hadn't logged out of the app before I ran the migration (?). So going to this path: http://name_of_my_app.herokuapp.com/logout fixed the problem for me.

Answer 5

Apparently deleting my entire app and then redeploying from scratch fixed it. I have no idea what the problem was.

Answer 6

I had a similar issue and ran heroku run rake db:reset and heroku run rake db:migrate to fix the issue. I guess that I just hadn't run the proper migrations to fix the problem.
