Ruby on rails problems on heroku

I've been working on a on uploading my RoR3 website onto Heroku.

Took me a while to get it up. Seems to work pretty good but when i try creating a project (my website manges donation projects) i get the next message:

We're sorry, but something went wrong. We've been notified about this issue and we'll t开发者_运维知识库ake a look at it shortly.

No idea what causes this it works fine on my localhost.

The normal Rails Error - Have a look at the Heroku Logs and check the Stack for more details then post them back on here.

Usually when I've had this problem, it's because I've forgotten to run db migrations at Heroku.

In terminal, in your rails app folder, run this:

heroku rake db:migrate
