I am a novice writing a simple address book app. It is just using the  
simple CRUD operations, but I would like to write a function for the  
index view that divides the records up by the first letter of the last  
name so I can have jump links at the top to take you to a specific  
group of records according to their last name. Should this function  
be put in the controller, or the model?

I think I would have a Model method that provides the records as an  
array of  
arrays, each element of the outer array being an array of records with  
the  
same first letter of the name. This would be asked for by the controller  
and  
passed to the view for display as appropriate. The view would put the  
links  
in using appropriate view helper methods.

Or perhaps the Model method would take a collection of records and  
convert  
it to the array of array form. Then one could do  
@records = Model.find(…).in\_groups or whatever the method is  
called
