Google App Engine Rails Template

Hi Christian

Thanks for the code sample.

I am very eager to use a standard Ruby development environment for App Engine without restarts as you have described.

I have spent several hours trying to use your code sample to configure a Rails project with GAE but so far have been unsuccessful.

Have you made any other significant changes to your Rails app besides what you mentioned?

Thanks,
Carson

My workaround in development mode so far: Simply using Webrick as usual
plus setting up the datastore in the controller (application_controller.rb).

if Rails.env=='development'
before_filter :setup_datastore
after_filter :teardown_datastore
end

protected

if Rails.env=='development'
import com.google.apphosting.api.ApiProxy
import com.google.appengine.api.datastore.dev.LocalDatastoreService
import com.google.appengine.tools.development.ApiProxyLocalImpl

class DevEnvironment
include ApiProxy::Environment
def app_id
'Dev Environment'
end
end

def setup_datastore
ApiProxy.environment_for_current_thread = DevEnvironment.new
ApiProxy.delegate = Class.new(ApiProxyLocalImpl).new
java.io.File.new('.')
#ApiProxy.delegate.set_property
LocalDatastoreService::NO_STORAGE_PROPERTY, 'true'
end

def teardown_datastore
#ApiProxy.delegate.get_service('datastore_v3').clear_profiles
ApiProxy.delegate = nil
ApiProxy.environment_for_current_thread = nil
end
end
