I'm doing maintenance work on a Rails site that's deployed using Phusion Passenger.

Hello, I'm looking for any pointers on how to write a rails web app without ActiveRecord. A doc or an example of a (not too complex) web app using storage backends other than a relational database would be greatly appreciated. It's not clear on what should be implemented in the model classes in order to make the rails app work without ...
I have a Ruby on Rails app running on my server, and I can't figure out how it was deployed (someone else set it up). The app is located in /var/www/myapp. Before it was deployed, I had been able to go in there and make minor edits to the app. The person helping me out with RoR then "deployed" it. It was unclear what deploying actually ...

The problem comes when I want to add recaptcha and a user signs up with openid. Apparently the verify_recaptcha method overrides the openid parameters. There must be a way to g...

I'm already using gravatar icons for the users of my web service. However, I'm finding several problems with this approach: Only a small percentage of the users take the time to set up a gravatar profile. My users are not tech-savvy, but would be likely to add a dedicated photo to my site. Users of my service are encouraged to use imag...
Hi all, I'm fairly new to both Rails and Heroku but I'm seriously thinking of using it as a platform to deploy my Ruby/Rails applications. I want to use all the power of Heroku, so I prefer the "embedded" PostgreSQL managed by Heroku instead of the addon for Amazon RDS for MySQL, but I'm not so confident without the possibility to acces...

I have a situation where I only use the create and edit actions for one model in the STI relationship, but I get an 'undefined method' error if I try to do a form for.

One of my favorite features of Google docs is the fact that it's constantly automatically saving versions of my document as I work. This means that even if I forget to save at a certain point before making a critical change there's a good chance that a save point has been created automatically. At the very least, I can return the documen...
