Errore parametri form_tag

Salve ragazzi,
ho un problema con form_tag
la pagina e’ cosi scritta:

Nuovo Numero

<%form_tag :action=>'cnew' , :user_id =>@user do %>

User id<%= text_field_tag 'user_id',@user %>

Numero di telefono<%= text_field_tag 'number' %>

<%= submit_tag "Aggiungi Numero" %>

<% end %>

nel controller
def cnew
@phone =Phone.find(:first , :conditions =>[“number =?”,
params[:number]])
if @phone.nil == true then
@phone.new
@[email protected]
@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) :stuck_out_tongue:

ciao,
A.

ok, trovato l’errore :wink:

nel controller hai:

if @phone.nil == true then
@phone.new
@[email protected]
@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 :wink:

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

ok, trovato l’errore :wink:

nel controller hai:

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

� meglio riscriverlo
cos�:
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 � risolto :wink:

ciao,

‘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 :wink:

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.

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
