How do I ignore folders and files when pushing to Heroku with a Rails app?

I have a Rails 3.2.8 application and I don't want to push my spec folder and test log to Heroku. How would I do this? What about with a staging remote?

Thanks.

Which type of database Cannot be used to deploy your Rails app to Heroku?

So, the reason why you cannot use SQLite on Heroku is because SQLite stores all database information in a file on disk, and because Heroku will delete the files on your disk, this won't work.

You could put them in .gitignore, but that will exclude them from your repository as a whole.

The better solution is to push them to Heroku but prevent Heroku from deploying them to your dynos. You can configure that with a .slugignore file.
