Maybe you shouldn't put business model in your view:

=> Person.rb def self.find_upcoming_birthdays    find_all(:conditions => "birthdate is NOT NULL") end

def <=>(other)    birthdate.strftime("%j").to_i <=>    other.birthdate.strftime("%j").to_i end

def age    ((Date.today - birthdate)/365.2422).to_i end

=> _upcoming_birthdays.rhtml <table>    <% @upcoming_birthdays.each do |upcoming_birthday| %>      <tr>        <td>            <strong><%= link_to "#{upcoming_birthday.name}", :controller => 'people', :action => 'show', :id => upcoming_birthday %></strong><br />            <%= upcoming_birthday.birthdate.strftime("%B %d") %><br />            <em>will be pluralize(upcoming_birthday.age + 1,'year') old</em><br />        </td>      </tr>    <% end %> </table>

=> Controller   @upcoming_birthdays = Person.find_upcoming_birthdays   @upcoming_birthdays.delete_if {|person|     Time.today.strftime("%j").to_i > person.birthdate.strftime("%j").to_i   }   @upcoming_birthdays.delete_if {|person|     person.birthdate.strftime("%j").to_i > (Time.today.strftime("%j").to_i) + 31 }

  @upcoming_birthdays.sort!

Just my $0.02.

Here’s how I find upcoming/recent birthdays in a Person model:

Find people with birthdays around a given date.
