Usare activerecord e fregarsene? 😃

Se ti serve perché devi fare una struttura ad albero con padri e figli,  
puoi usare acts\_as\_tree… Cerca di non interfacciarti mai direttamente  
con il db tramite query, ma di usare sempre activerecord…

come non detto, avevo un errore stupido nel codice

grazie mille e scusate il disturbo :]

Saluti Andrea

PS: di seguito riporto cmq il codice che ho usato(funzionante)

Travel.transaction do  
Location.transaction do  
begin  
session[:myTravel].travel.save  
session[:myTravel].locations[0].travel\_id = session  
[:myTravel].travel.id  
session[:myTravel].locations[1].travel\_id = session  
[:myTravel].travel.id

```
               session[:myTravel].locations[0].save
               session[:myTravel].locations[1].save

           rescue Exception => exc
               render :inline => "transaione fallita: #

```

{exc.message}"  
end  
end  
end
