Salve ragazzi,  
come da voi suggerito sto cominciando a dare un occhiata al  
development.log.

Ho riscontrato questo DEPRECATION WARNING:

Processing ViewController#scarica (for 79.51.42.228 at 2009-05-04  
17:04:19) [GET]  
Session ID: dd34c9a8d401cbb213b681c0c9a46d42  
Parameters: {“title”=\>“google-desktop”, “id”=\>“213”,  
“keyword”=\>“file-search”}  
Rendering template within layouts/down\_guida  
Rendering view/scarica  
DEPRECATION WARNING: truncate takes an option hash instead of separate  
length and omission arguments. (called from  
\_run\_rhtml\_app47views47view47scarica46rhtml at  
/home/softwav4/it/app/views/view/scarica.rhtml:21)  
Completed in 279ms (View: 85, DB: 171) | 200 OK  
[[http://www.software-windows.net/213/software/file-search/google-desktop/download.html](http://www.software-windows.net/213/software/file-search/google-desktop/download.html)]

il warning penso si riferisca all’esecuzione di:

temp=truncate(strip\_tags(@pages.text),200)  
@description=“#{temp.split[0…19].join(” “)}…”

mi sapete dire perché?

Grazie

Luigi

Molte API stanno passando da una “logica” di passaggio di parametri a  
lista piatta ad un hash.  
In effetti è più facile ricordare la chiave dell’hash che non la  
posizione in una flat list (IMHO)…

Nel caso di truncate, riprendendo dalla documentazione:

truncate(“Once upon a time in a world far far away”)

# =\> Once upon a time in a world f…

truncate(“Once upon a time in a world far far away”, :length =\> 14)

# =\> Once upon a…

truncate(“And they found that many people were sleeping better.”,  
:length =\> 25, “(clipped)”)

# =\> And they found that many (clipped)

truncate(“And they found that many people were sleeping better.”,  
:omission =\> “… (continued)”, :length =\> 15)

# =\> And they found… (continued)

Quindi dovresti utilizzare:

temp = truncate(strip\_tags(@pages.text), :length =\> 200)
