Hi I wrote this method to check for the availability of a studio :

def check\_dispo(date, time, time\_duration, week\_duration)  
i = 0  
end\_time = time + time\_duration.strftime(’%H’).to\_i_3600 +  
time\_duration.strftime(’%M’).to\_i_60  
while i \< week\_duration  
studio\_bookings = StudioBooking.find(:all, :conditions =\>  
[“start\_date = ?”, date])  
for studio\_booking in studio\_bookings  
studio\_booking\_end\_time = studio\_booking.time +  
studio\_booking.time\_duration.strftime(’%H’).to\_i_3600 +  
studio\_booking.time\_duration.strftime(’%M’).to\_i_60  
unless time \>= studio\_booking\_end\_time || end\_time \<=  
studio\_booking.time  
return false  
end  
end  
i += 1  
date = date + 7  
end  
return true  
end

it returns false in case it’s booked but returns ‘nil’ instead of true  
otherwise ☹

HELP PLEASE !!!
