problem with RESTful forms in Rails 3 - ruby-on-rails-3

Question

okay, so basically, I have a normal form for my model:
= form_for #operator do |f|
blah blah blah
In my operators controller, i have this:
def new
#operator = Operator.new
#operator.build_user
respond_to do |format|
format.html {}
end
end
def create
#user = User.create(params[:operator].delete(:user))
#user.update_attributes(:login => #user.email)
#operator = Operator.new(params[:operator].merge(:user => #user))
respond_to do |format|
if #operator.save
format.html {redirect_to new_operator_aircraft_path(#operator)}
else
format.html { render :action => "new", :error => #operator.errors }
end
end
end
very basic stuff. I have some validates_presence_of stuff in my model so naturally when I submit my form, it should show me that I have errors(and keep the fields I have filled up)
Right so far? yeah. The problem is, it seems I am posting to /operators and that's what renders. I seem to have forgotten about what happens in Rails2.3+ but shouldn't I be redirected to /operators/new again? or was that the intended behavior all along?

Here's what I think you are asking:
After I submit a form with errors, why does the URL
read "/operators" rather than
"/operators/new".
Thanks to resourceful routing, when submitting a form via POST to "/operators" the create action is called on the OperatorsController. If you encounter errors when saving your operator, you've instructed the controller to render the new action within the same request.
render :action => "new", :error => #operator.errors
This means a redirect is not occurring and therefore the URL remains "/operators".
If a redirect were to occur, you would lose all the state information of the #operator object in the current request, including the errors you encountered as well as the form values you just submitted.
In other words, working as intended.
