I have a simple model structure. Projects have many notes.

For each of my project pages I would like to have a simple display like  
the following:

Project Name  
Week of MM/DD/YYYY  
Notes that fall under that week

So the output would be like the following:

Test Project (project.name)  
10/08/2007 (note.created\_on)

- Test (note.body)
- Test 2  
10/01/2007
- Test 3

Any thoughts on how I can craft an ActiveRecord :find to appropriately  
group my notes by date by project like this?

Thanks!

If all else fails, go to the source and learn the algorithm to convert a  
date to a week number:
