I'm currently in the process of developing a digg-like Ruby on Rails application for my degree's Final Project and I'm stuck in the 5 point ranking algorithm. There are a couple of factors that need to be involved, here's a breakdown : Users <ul> <li>They'll have a personal 5 points ranking per category with 5 being the best and 1 being worst (Think of it as a 5 star ranking), so i could perfectly have IE. A 2 star ranking on the History category and a 5 star ranking on the Technology category.</li> </ul> Stories <ul> <li>Each story will be classified with just 1 category, when the user posts the story, (and here's the one of the problems) it'll be given a "base ranking" based on the ranking of the user in that category. IE let's say i have a 5 star ranking in the technology category then if I post a story in it's be given a base ranking of 5 stars because i have a 5 star ranking in that category.</li> </ul> In the end, i have 3 rankings. The avg user ranking, the ranking of the user per category and the ranking of each story. I've found this link : <a href="http://www.seomoz.org/blog/reddit-stumbleupon-delicious-and-hacker-news-algorithms-exposed" rel="nofollow noreferrer">http://www.seomoz.org/blog/reddit-stumbleupon-delicious-and-hacker-news-algorithms-exposed</a> It decomposes various ranking algorithms, the Reddit algorithm seems to adapt my needs, I believe that it's just a matter of replacing the X = D - U variable with a proper equation that avgs the 1-5 points that can be given. What do you guys think? Thank you, Josh

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
