I am also in the process of building my RoR app and need a wysiwyg editor. I have found a gem which installs tinyMCE on your rails app: https://github.com/kete/tiny_mce https://github.com/kete/tiny_mce It took me 3 minutes to integrate it into my app. My only backdraw is that it lacks the ability to upload an image - so I am looking into that now. Good luck.
