Hi, I’m new in Ruby on Rails and I don’t know how can I achive  
something like this:

@switchs = Switch.find(:all)  
for switch in @switchs  
if current\_user.shifts.count(:all,:conditions=\>[“date = ? and  
shift = ?”,switch.destiny\_date, switch.destiny\_turn]) !=0  
@valid = switch  
@valid.merge(cambio)  
end  
end  
return @valid

Let me explain. I just want to put in the same @valid object, switchs  
that satisfy the “if” condition. So, I have to loop for every switch  
and just select those ones that satisfy the condition. Is there any  
way to achieve this???

Thanks in advance.
