Heroku now has an API (accessible from the command line, a Ruby library, or REST calls), revision control on all apps with Git, and remote access to the Git repository.

The combination of these new features means that you can now work on your apps using the local tools you love – like TextMate, vi, or emacs – and still get the benefit of zero-configuration deployment to Heroku.

How does it work? Grab the Heroku gem with “gem install heroku”. A sample work session looks like this:

heroku clone myapp cd myapp ruby script/server …edit locally… git add . git commit -m “local changes” git push

The final step will deploy the app to Heroku,...

Backstory: A Fiery Debate

Writing a user model and the standard login authentication code seems like busywork to a lot of coders. In fact, many people expected a next-generation app framework such as Rails to handle this for you. After all, Django does. Initially the login engine for Rails seemed to fill this slot, but following a fair amount of controversy over best practices, the login engine was killed by its creator.

With our BDfL having forever cursed prebuilt login systems, the Rails community mostly stopped trying to make them. Yet, this puts us back at square one: developers are annoyed at the amount of boilerplate busywork that is necessary for almost every web app they write.

RSpec 1.1 is now a part of the default plugin kit for Heroku apps.

We’ve been fans of RSpec for a while now, and feel that it represents the future of TDD/BDD for the Rails world. If you’re not familiar with RSpec, read up and then give it a try.

You don’t need to install anything to use RSpec in your Heroku app, but you do need to initialize the spec/ and stories/ directories by running the rspec generator. Just open the Generate dialog, type in rspec, and click Run.

Once you’ve written some specs, you can run them the usual way: open a rake console and type spec. You can still run your Test::Unit tests with the test command, or you can run tests followed by...

There are now two access levels for collaborators on Heroku apps:

• Full edit access, which allows access to everything: editing code, importing or exporting the database, changing the settings, etc.
• View-only access, which allows the user to view the app only. That is, they can visit the app url (myapp.heroku.com) but not any of the settings pages or the edit url (edit.myapp.heroku.com).

For example, a client who wants to use the app but neither needs nor wants access to the code could be set as a view-only user.

If your app sharing is set to public, the view-only access level has no use.

Do note that these settings have no effect on users changing your app’s data through the...

Behold: the Heroku gems/plugins manager.

This has been one of our most requested features to date, and we’re glad to finally get this released. Although you could manually upload plugins previously, this will make the process a lot smoother. (You can still manually manipulate the files in your vendor directory if you prefer.)

To get to the manager, open your vendor directory in the lefthand filenav, and click the link that appears at the top:

You can search by name, or browse the list of 2500+ gems and 1000+ plugins. Once you find what you’re looking for, click on Install in the righthand column to install it into your app. Click Remove to remove it if it’s no longer...
