We have decided to use Rails/Oracle for a new project. My understanding is that ActiveRecord does not support bind variables and that this hamstrings Oracle's ability to cache queries and leads to significant performance problems. Cursor sharing has been said to help, but not completely, solve this problem. If this description is reas...
I am working on a RoR project which outputs XML to RESTful requests. The problem is it includes the "updated-at" and "created-at" fields in the output. I have tried using: :exclude -> [ :created_at, :updated_at ] and :exclude -> [ 'created-at', 'updated-at' ] but the output still renders them. How do I exclude them from the ren...
I just got burned because I used find_index on an array on my dev box (OSX with Ruby 1.8.7) and the deployment machine runs Ruby 1.8.6. (What's the difference between find_index and index? The latter works on 1.8.7 and 1.8.6) So that got me thinking: what's the best way to force Rails to run with a specific Ruby version? Since it's pr...

For my side project kwiqi, I use ActionMailer's 'receive' method to process incoming email messages for tracking my expenses. Heroku doesn't have a local mail server running that same code will not work. One solution I've thought of is to periodically hit a controller action that will pull messages from Gmail. Are there other solution...
This is more of a style question, I'm wondering what other people do. Let's say I have a field in my database called "status" for a blog post. And I want it to have several possible values, like "draft", "awaiting review", and "posted", just as an example. Obviously we don't want to "hard code" in these magic values each time, that w...
