I run a Rails web app that generally has moderate traffic (100 requests/hour at most). However, I get a relatively high burst of traffic once every few weeks (50 requests/sec for 2 hours) at a time that I can anticipate. Over the next few months, I expect both the moderate and peak traffic to increase, but their relative magnitudes will ...

I am using single table inheritance in StudentHours and TeacherHours, which have a parent Hours. The model code is mostly in hour.rb, and very little in student_hour.rb and teacher_hour.rb Now I have realized that most of the controller code is duplicate as well, so I've created a hours_controller to be the parent of students_controlle...

I'm fairly new in the Ruby + Rails scene. Although I have a very strong understanding of design patterns, data structures and algorithms - there's a ton of "must have" plugins that I haven't had a chance to run into yet. There's things for migrations, resource controllers and a myriad of other plugins that make developing for these platf...

I have a nice RESTful controller in my Rails application that uses responds_to to distinguish between requests for HTML and CSV requests, serving the HTML if one uses the URL normally, and the CSV if one adds ".csv" to the end of the URL. In my view layer ERB file, I want to have a link to the CSV. I could just get the URL for the appro...
