additional information:

db
your problem db related (as you've suggested)
heroku has 2 types of error - standard "rails" errors & heroku platform errors:
rails error
heroku error
--
error
these errors standard rails apps running on heroku - difference rails error 1 derived rails app itself; heroku error raised heroku platform
heroku errors mean application cannot load reason; typically because it's unable connect db, or db doesn't have right data tables.
to fix this, first need ensure you're using database in production (heroku's postgres db highly recommended):
#config/database.yml production: .... after have set & pushed heroku, need ensure db populated right tables. this, run heroku run rake db:migrate in local cmd
update
the way make sure have production db use heroku postgres db, should come standard in heroku app dashboard
if need add heroku postgres db dashboard, need add add-on here
once db in dashboard, click on & should come postgres interface. can see how connect db in ruby here; should use details provided postgress add-on in app's dashboard
typically, heroku-compatible database.yml this:
#config/database.yml production: adapter: postgresql encoding: utf8 database: ********* pool: 5 username: ********* #-> *** data heroku's postgres user details page password: ****** host: ******
