The same is applicable for a Merb app, but there might be a better way to do it. Just put the following your application controller.

Setup Paperclip plugin with Amazon S3 to upload videos in rails
This is taken from Clayton Lengel-Zigich. Thanks.
Create a video model.rb
Configure the config/s3.yml file
Configure and install right_aws gem
Then run: sudo rake gems:install & sudo rake gems:unpack
Create a videos controller with the prospective views for the uploading
Configure flash player to display video
1. Download JW FLV MEDIA PLAYER (mediaplayer.zip download link)
2. Copy and paste the player.swf file at public/flash/player.swf
3. Copy and paste the swfobject.js at public/javascript/swfobject.js
4. Configure your application.html.erb file to call swfobject.js in the head
That’s it, you should now be able to upload flv video files and view them in a flash player by going to http://localhost:3000/videos. For instructions on converting quicktimes videos to flash videos on file upload take a look at Jim Neath’s tutorial on converting videos with rails.
Development vs Production mode
It’s a good idea to create a bucket for development and a bucket for production. If you decide to, you can do the following.
Note:this assumes you started your app with bort, and already have a settings.yml that gets loaded by the load_config.rb file using APP_CONFIG = YAML.load_file(”#{RAILS_ROOT}/config/settings.yml”)[RAILS_ENV].symbolize_keys)
In config/settings.yml
In video.rb
Using Gmail with IMAP to Receive Email in Rails (cron job version)
This pretty much comes about because of RailsTips and Peepcode. Thank you guys.
Goal
You want your user to be able to send an email and have that email get posted as a comment to the rails app.
Requirements
1. Your rails app should already have the ability to send out emails
2. Your Rails app must already be capified via Capistrano or similar with some type of deployment recipe
3. You need an additional gmail or google apps account with imap enabled
4. You need the ability to run cron jobs on your server
Configuration
First, setup the cron task and make it easy to run with cap deploy:start and cap deploy:stop
Create file lib/tasks/chores.rake
Create file config/cron.erb
Add the following near the end of your deploy.rb file
Second, setup the login information for the gmail mail account we will use to receive emails through.
Create file config/mail.yml and configure for imap
Install lockfile and tmail cause your gonna need them:
sudo gem install lockfile
sudo gem install tmail
Edit environment.rb
Retrieve the email and save to the database
Edit lib/tasks/chores.rake and put the following code inside the each_minute task. (credit for this goes to John of RailsTips.org though I added a quick fix to handle multipart emails)
Deployment
Deploy your app as usual with cap deploy
Next, run cap cron:start to start up the cron task. This will run every minute.
Send an email to the account you specified in mail.rb and after one minute you should see the email saved as a comment on the app.
