Hi…I need some advice:

A formular which includes 3 partials  
The partial will be chosen by userinput stored in a session

Controller:  
def new  
@booking = Booking.new  
@booking\_partial = partial\_choice(session[:pre][:fahrt]) # 1,2 or 3

this works fine, but if the validation fails the partial will not be  
shown again…!

Looks like the ‘partial\_choice’ is not getting information then. I  
dont see the point where to feed that info in again.

Thanks for your help  
Werner

When your save fails, are you re-seeding the @booking\_partial value?

def create  
if @booking.save  
# the happy path  
else  
@booking\_partial = blah blah blah  
render :action =\> ‘new’  
end  
end
