I simply want a contact us form with name, email and message fields in my Rails app, I don\'t want to save(permanently) the message I just want to send the message as an ema
I've written a Rails Engine https://github.com/jdutil/contact_us that you can easily drop into any Rails 3+ application. I didn't add a Name field to the form, but you could fork the repo then modify it to suit your needs. It does require the Formtastic gem since I wanted an easy way to hook into peoples existing form styles though.
To install the Engine add the contact_us gem to your Gemfile:
gem 'contact_us', '~> 0.4.0'
Run bundle and the install rake task:
$ bundle
$ bundle exec rake contact_us:install
Then just modify the generated initializer in /config/initializers/contact_us.rb to have the email you want the form submissions sent to.
