errore parametri form_tag

Salve ragazzi,
ho un problema con form_tag
la pagina e' cosi scritta:
<h1>Nuovo Numero</h1>
<%form_tag :action=>'cnew' , :user_id =>@user  do %>
<p>User id<%= text_field_tag 'user_id',@user %></p>
<p>Numero di telefono<%= text_field_tag 'number' %></p>

<p>
   <%= submit_tag "Aggiungi Numero"  %>
</p>

<% end %>

nel controller
  def cnew
    @phone =Phone.find(:first , :conditions =>["number =?",
params[:number]])
    if @phone.nil == true  then
      @phone.new
        @phone.user_id=@user
        @phone.number=params[:number]
      @phone.save
    end
    if @phone.save
      redirect_to @phone
    else
       render :action => "new"
    end
  end

Quando premo il pulsante  aggiungi numero mi restituisce questo errore
undefined method `nil' for nil:NilClass
Potreste aitarmi a capire gli errori?
Grazie Fdibenedetto

sarebbe utile conoscere un altro po' di errore, generalmente indica
anche il file e la riga che hanno restituito l'errore, altrimenti rimane
un po' dura (anche se sarebbe comodo avere un debugger innestato nel
cervello :D) :P

ciao,
A.

ok, trovato l'errore ;)

nel controller hai:

if @phone.nil == true  then
       @phone.new
       @phone.user_id=@user
       @phone.number=params[:number]
       @phone.save
end

è meglio riscriverlo 
così:
if @phone.nil? #<= qui era l'errore, il controllo lo fai con 'nil?'
   @phone.new(:user_id =>  @user, :number =>  params[:number])
end

if @phone.save #etc...

ci sarebbero altri miglioramenti sintattici e logici che potresti 
apportare, in ogni caso l'errore è risolto ;)

ciao,
A.

Andrea, ho provato a fare cio che mi scrivi con qualche modifica
ti riporto il codice della view e del controller
la view e'
<h1>Nuovo Numero</h1>
<%form_tag :action=>'cnew' , :user_id =>@user  do %>
<p>User id<%= text_field_tag 'user_id',@user %></p>
<p>Numero di telefono<%= text_field_tag 'number' %></p>

<p>
   <%= submit_tag "Aggiungi Numero"  %>
</p>

<% end %>

il controller cnew l'ho cosi modificato:
    @phone =Phone.find(:first , :conditions =>["number 
=?",params[:number]])
   if @phone.nil?
    @phone=Phone.new(:user_id =>   params[:number], :number => 
params[:number])
  end
    if @phone.save
      redirect_to @phone
    else
      render :action => "new"
    end
  end

ma mi restituisc questo errore
Mysql::Error: Duplicate entry '2' for key 1: INSERT INTO `phones` 
(`number`, `created_at`, `updated_at`, `user_id`) VALUES('3', 
'2010-08-19 13:04:34', '2010-08-19 13:04:34', 3)

Ok funziona !!
grazie andrea!!
i tuoi consigli mi hanno risolto questo problema .
capisco bene  e' un piccolo problema ma all'inizio e' tutto cosi 
complicato!!!
Perfavore mi puoi spiegare la logica if @phone.nil?
if @phone.nil?
a rigor di logica s'intende che se non se non esiste il record allora 
esegue il codice sottostante ma perche il ? e non ==TRUE

Grazie sempre

'nil?' è un metodo, restituisce 'true' se l'oggetto che lo ha chiamato è nil

non ha senso confrontarlo ulteriormente con un valore bool, sarebbe come
dire:

if (1 > 2) == false

tra l'altro, il primo errore che ricevevi era dovuto al fatto che non
esiste un metodo '.nil' per gli oggetti, non per default ;-)

NOTA  A MARGINE: è vero che spesso la pratica insegna più della teoria,
ma questo non significa che per pilotare un elicottero sia sufficiente
salirci sopra e provare ad accenderlo. magari con un po' di
documentazione e qualche ricerca su google potresti anche imparare di 
più.
ciao,
A.

Infatti occorre fare l'uno e l'altro
Grazie sempre per i tuoi suggerimenti

si, ma prima inizia con un buon manuale (anche più di 1 se puoi, ti 
consiglio questi: http://www.pragprog.com )

comunque:
if @phone.nil?

è come scrivere:
if @phone == nil
