Help building some pages

[paulo larini]

Hi, I am using Rails, and I am new to web development. So I need some directions to follow.

My application needs to display a list of cars (in a grid).
When one car is selected, I need to display a list of sales of this car in a grid, inside a kendoWindow.

Whats is the best way to do this?
Where I need to write my javascript initialization code?

Thanks.
