Salve,  
in Rails 2 funzionava perfettamente il comando all’inizio del  
controller:

layout ‘law’, :except=\>[:not\_found]

in Rails 3 non funziona più anche se ho trovato indicazioni in merito e  
la sintassi è identica.

Dove sto sbagliando?

Grazie

Infatti non riesco a capire…comunque quello che succede è che:

class ViewController \< ApplicationController

require ‘rmagick’  
layout “view”, :except=\> [:picture]

def index  
…  
…end

def picture  
…

end

ma la vista picture continua ad usare il layout view a meno di mettere  
nel def picture il comando render :layout=\>false

Non riesco a capire.

Non che hai un layout application uguale a view?

Ho controllato, purtroppo no il layout application è quello di default e  
diverso dal layout view.

Perdonate l’attesa, no, non funziona neppure only!

…bah!

Nel log viene chiaramente chiamato il layout view:

se nella vista disclaimer dichiaro layout=\> false allora:

Per allargare la fiera delle ipotesi… non è che c’è di mezzo qualche  
redirezione o render :action? Controlla nel log tutte le linee che  
iniziano con " Rendered" e verifica quali view e partial vengano  
realmente usati.

Googlando però vedo che non sei l’unico con questi problemi

Per curiosità, only funziona come ti aspetti?

layout “view”, :only =\> :index

Prova anche senza l’array.

In ApplicationController non ho alcuna chiamata a layout, la chiamata al  
layout sta solo in ViewController.

Hai un’unica chiamata a layout nei controllori ViewController +  
ApplicationController?
