Salve gente,

qualcuno ha idea di come effettuare una update su un  
oggetto AR senza che siano chiamati i metodi di  
callback?

L’idea è, sostanzialmente, di avere un comportamento  
di default quando c’è il #save di un oggetto, ma di  
non averlo in una specifica situazione.

Una soluzione è ovvia, mettere nel modello una flag  
#run\_behaviour e verificarla nella callback, ma è un  
po’ una porcata e non mi piace.

Non esiste per case un #save\_without\_callbacks da  
qualche parte?

Avevo speranze in AR::Base.update, ma purtroppo anche  
quello richiama AR::Base#save 😕

```

C’è update\_without\_callbacks, credo che faccia al caso tuo.Lo puoi vedere  
in  
console con tuocoso.methods
