Hello  
begin  
if(nil|pattern.match(details)) then  
id=$1  
rec=Scans.find(id)  
rec.scannable=MARKTRUE  
rec.save  
else  
badpattern=true  
end  
rescue RecordNotFound  
badpattern=true

end

I still get the prog stopping and printing out the exception  
Pl choose alert action? 3 1000

uninitialized constant RecordNotFound (NameError)

This is telling you that RecordNotFound has not been defined. Maybe  
you’ve forgotten to include something?

I guess Junkone is refering to ActiveRecord::RecordNotFound  
exception, but he doesn’t give much info.

Furthermore, if it’s a ActiveRecord related problem, it should be  
asked in Rails-Talk mailing list.
