Strange syntax error in while loop

ruby-talk
1

Hi,

I'm getting the error

SyntaxError in OrderController#confirm
/usr/local/apache2/htdocs/easyrx/app/controllers/order_controller.rb:
11: syntax error, unexpected kEND
    end ^
/usr/local/apache2/htdocs/easyrx/app/controllers/order_controller.rb:
33: syntax error, unexpected $end, expecting kEND

in this method:

        def confirm
                i = 0
                while params[:prescription_number + i.to_s] != nil and
params[:description + i.to_s] != nil
                        session[:prescription_number + i.to_s] =
params[:prescription_number + i.to_s]
                        session[:description + i.to_s] =
params[:description + i.to_s]
                        i++
                end # line 11
        end

Thanks for your help, - Dave

    i++
  end

Ruby doesn't have the ++ operator and parses the above as binary plus followed
by unary plus, i.e. "i + (+end)". Thus the syntax error.

HTH,

Ruby doesn't know ++, so you have to write i+=1
