    This is pretty similar to: Rails: exclude anything from version control? Here is my answer from that.

    DHH just posted on Twitter that there will be a default .gitignore in Rails 3, which includes:


    This is usually what I exclude. Some people also like to exclude the database.yml file if it’s going on a public repo and you don’t want to expose your database passwords.


    # TODO Comment out this rule if you are OK with secrets being uploaded to the repo
    # Only include if you have production secrets in this file, which is no longer a Rails default
    # config/secrets.yml
    # dotenv
    # TODO Comment out this rule if environment variables can be committed
    ## Environment normalization:
    # these should all be checked in to normalize the environment:
    # Gemfile.lock, .ruby-version, .ruby-gemset
    # unless supporting rvm < 1.11.0 or doing something fancy, ignore this:
    # if using bower-rails ignore default bower_components path bower.json files
    # Ignore pow environment settings
    # Ignore Byebug command history file.

    Keep in mind that Heroku’s slug compiler has a very similar feature using a file named .slugignore. This file syntax is roughly the same as in .gitignore.

    So you can continue working as usual (ie: storing PSD files, spreadsheets and other common files) but remove them at runtime on Heroku to lower the slug’s size (< 20MB sounds good).

    On Heroku, the best starting option is:


    There is a project on Github dedicated to storing accurate gitignore files for different languages, editors, etc. While the project does not currently have an entry specific to Heroku, you might still find it useful to review. The project is here and the Rails .gitignore is here.

    FYI, I first found out about this project from this Stack Overflow question.
