Generating PDF's via Delayed Job while maintaing a RESTful pattern.
Hi, currently I am running a Rails app on Heroku, and everything is working great with exception of generating PDF documents that sometimes contain thousands of records. Heroku has a built-in timeout of 30 seconds, so if the request takes more than 30 seconds, it's abandoned. That's fine, since they offer delayed_job support built-in. ...
How do I require a specific version of a ruby gem?
Specifically, the ruby-oci8 gem. I have both 1.0.7 and 2.0.4 installed. I want 1.0.7.

Best way to handle multiple tables to replace one big table in Rails? (e.g. 'todo_items1', 'todo_items2', etc., instead of just 'todo_items')?
Update: Originally, this post was using Books as the example entity, with Books1, Books2, etc. being the separated table. I think this was a bit confusing, so I've changed the example entity to be "private todo_items created by a particular user." This kind of makes Horace and Ryan's original comments seem a bit ...

How do I use Ruby metaprogramming to refactor this common code?

Specifically, that pattern is the following: namespace :foobar do desc "Fr...
