Hello,
I was thinking about doing an alphabetical navigation for i.e list of
users (there would be alphabet at the top of the list and by clicking on
a character the list would get filtered).
I did some googling but didn’t find any plugin or quick hack sorting
this problem out. It’s however such a common thing that I was wondering
whether there isn’t really some.
Any suggestions or ideas are very welcome
Thanks
Jakub
Wow…
I was just finishing up something on just that topic. Let me know if
this
helps you and give me some feedback if you can!
maybe something like
view:
<% (‘A’…‘Z’).each do |letter| -%>
<%= link_to letter, :controller => :user, :action => :list,
:starts_with => letter -%>
<% end -%>
<% @users.each do |user| -%>
…
<% end -%>
model:
class User < ActiveRecord::Base
def find_by_last_initial(initial)
# note: use of mysql db functions may not be portable
find(:all, :conditions => [“UCASE(LEFT(last_name,1)) = ?”,
initial.upcase]
end
end
controller:
class UserController < ApplicationController
def list
if params[:starts_with]
@users = User.find_by_last_initial(params[:starts_with])
else
@users = user.find(:all)
end
end
end
Thank you very much Chris,
that’s exactly what I was dreaming about

Hello Brian,
I’m sorry I overlooked your post and implemented it by Chris’s
suggestion. I will try, however, to look at your writing and give you
some feedback.
Cheers
Jakub
