Is you question about where those methods should go? They can, and
usually should, go in the model.

class Product

def self.find_all
   find(:all, .....)
end

def self.select_fruits(parameters)
    find(:all, :conditions...
end

end

--- controller --

fruits = Product.select_fruits(:fruit_type = params[:....])
