Generating Models based of other models ruby on rails

Question

So I have a model of Items with the following fields:

• Name (string)
• Description (text)
• Hider (string)
• Seeker (string)
• Long (float)
• Lat (float)
• Keyword (string)
• Found (boolean)

Highscore should have the following fields:

-Username (name) -Points (int)

I want to create a model of highscores that will iterate the Item model and find entiers that have the boolean being true. Then add the seeker to the highscore table with a point. If the user already exists then, just add an extra point to his entry.

How would I go about designing this type of database...

Answer 1

I will never suggest iterating approach here. This is database we are talking about, and linear iteration over the data is unrealistic.

What you can do is use Observer . Read about them here - http://api.rubyonrails.org/classes/ActiveRecord/Observer.html

With this, you can check at the save and update callbacks and depending upon your boolean value, you can create/update the HighScore record.
