Salve ragazzi,  
come faccio a costruire una :conditions di questo tipo:

cond\_selection = { }  
cond\_selection[:category\_id]=@selected\_cat if not  
params[:categoria]==nil  
cond\_selection[:public]=true

(cond\_selection[:license\_id]=1 or cond\_selection[:license\_id]=3)

@guides=Guide.find(:all,:order=\>‘title’,:conditions=\>cond\_selection)

* * *

Per intenderci mi serve che la vengano raccolti tutti i record che hanno  
license\_id=1 oppure =3

Grazie mille!

Luigi

Forse mi sono espresso male:

la stringa che non funziona è:

cond\_selection[:license\_id]=1 or cond\_selection[:license\_id]=3)

Grazie

prova qualcosa tipo:  
@guides = Guide.find :all, :order =\> ‘title’, :conditions =\>  
{:license\_id =\> [1, 3]}
