Ruby on Rails app on Google App Engine
Can anyone give me some pointers on how I could deploy my rails app to GAE? I've been reading about it, but it seems to be a fairly complicated task.
I tried with the google-appengine gem, but its not a piece of cake either.
Has there been any progress with the DataMapper adapter or will I need to make changes to my models?
I was hoping to see a full-detail tutorial about it, but those that I found were somewhat out-of-date.
Deploying Rails on Google's App Engine has become a lot easier than it used to be. There are a couple of caveats you should be aware of:
- App Engine only supports the Python and Java environments so for Rails you will be deploying on JRuby
- App Engine's datastore is based on BigTable so you won't be able to use ActiveRecord on a relational database (if you want your datastore hosted in AppEngine). But as @Geoff Lanotte as pointed out there is a Datamapper adapter you can use
- Pre-deployment testing is done within Google's sandbox tools as opposed to things like
script/server
Some other resources you might consider:

You can deploy Ruby on Rails on Google Compute Engine if it works for you. Compute Engine is Iaas (Infrastructure as a Service) and it is used by Google App Engine, which is PaaS (Platform as a Service). Compute Engine is one abstraction layer lower (you can access OS resources, like: file system, network etc.).
