hash problem any ideas ?

on controller i have this:

ldaphash = {}

ldap.search( :base => treebase, :filter => filter ) do |entry|

email = entry[:mail].to_s
uid = entry[:uid].to_s
fullname = entry[:cn].to_s
fullname = Iconv.iconv("ISO-8859-1", "UTF-8", fullname)
@fullname = fullname

if email != '''' && uid != ''''  then
#render :text => "#{fullname} (#{email})"
ldaphash["name"] = "#{fullname}"
ldaphash["email"] = "#{email}"
ldaphash["uid"] = "#{uid}"
end
end

now on the view page I try to access that hash.

<% ldaphash.each_pair do {key,val} %>
<%= "#{key} => #{val}" %>
<% end %>

Since I am total noob with these hashes on ruby any ideas ?

Re: hash problem any ideas ?

ok now i get error

You have a nil object when you didn''t expect it!

view is now

<% @ldaphash.each_pair do |key,val| %>
<%= "#{key} => #{val}" %>
<% end %>

If I create simple file like this test.rb

ldaphash = { }

 ldap.search( :base => treebase, :filter => filter ) do |entry|

email = entry[:mail].to_s
uid = entry[:uid].to_s
fullname = entry[:cn].to_s
fullname = Iconv.iconv("ISO-8859-1", "UTF-8", fullname)
@fullname = fullname

if email != '''' && uid != ''''  then
ldaphash["name"] = "#{fullname}"
ldaphash["email"] = "#{email}"
ldaphash["uid"] = "#{uid}"
end

ldaphash.each_pair do |key, val|
puts "#{key} => #{val}"
end


and run it then it works on command line but not on the web ?
