Ciao a tutti,

sto switchando per la prima volta un’applicazione RoR in production  
environment.

Lo switch in se’ ha funzionato senza troppi inghippi  
e sto giusto verificandone le differenze dal development environment.

Ecco la domanda:  
adesso giustamente i messaggi d’errore non vengono piu’ mostrati con lo  
stack per il debug, bensi’ al pubblico appare un semplice messaggio

“Application error (Rails)”

Sto cercando di capire dove e come posso modificare questo messaggio,  
per esempio facendo il redirect a /500.html oppure a un  
controller+action  
per gestire eventuali errori.

Grazie  
Franco

Ciao Franco,  
all’interno di app/controllers/application.rb puoi inserire:

def rescue\_action\_in\_public(exception)  
render :template =\> “mycontroller/myerror”  
end

o rendere l’html direttamente.

Trovi maggiori informazioni qui:
