Say I have a "Member" ActiveRecord object with a typical integer id attribute, and a string 'username' attribute.
If I generate routes for members using map.resources :members, then the output from the edit helper is: edit_member_path(@member) => "members/23/edit"
My goal is that I really want: edit_member_path(@member) => "members/billybob/edit"
Where instead of using .id it uses .username so that the links generated by all of the different helper methods are prettier and memorable.
Is this possible via some kind of option? Can I simply replace these helper methods with new implementations? I don't even know where these implementations are or what they really look like.
