hi im just wondering if why the build_book_reservation is not working
this is my applicationcontroller
helper :all # include all helpers, all the time
private
def current_reservation
@reservation ||= Reservation.find(session[:reservation_id]) if
session[:reservation_id]
#last assigned value will be returned as default.
end
def create_reservation_session(id)
session[:reservation_id] = id
end
def destroy_reservation_session
session[:reservation_id] = nil
end
and im trying to use it here
def new
@book_reservation = BookReservation.new
end
def create
@reservation = current_reservation
@book_reservation=@reservation.build_book_reservation(params[:book_reservation])
if @book_reservation.save
#If success set session
create_reservation_session(@reservation.id)
#redirect_to root_url, :notice => "Successfully created book
reservation."
else
render :action => ''new''
end
end
it raises undefined methodbuild_book_reservation'' for nil:NilClass`
error
model/book_reservation.rb
belongs_to :reservation
model/reservation.rb
has_one :book_reservation

Thanks. I don''t know whether your session is correct. Have a look at the Rails Guide on debugging to see suggestions on how to debug your code. Then you can work out exactly where it is going wrong.
