rspec users - Apr 2010 - multiple return values with stub

I have a helper method

     def login_as(role)
         user = stub_model(User)
         user.stub(:is_administrator?).and_return(role == :admin)
         User.stub(:find_by_id).and_return(user)
         session[:user_id] = user.id
         user
     end

which has been dandy until yesterday. I am now working on an admin 
controller for user maintenance, and in it, I want to do this:

         before :each do
             login_as(:admin)
             @some_user = stub_model(User, valid_user_hash)
             User.stub(:find_by_id).and_return(@some_user)
         end

which obviously conflicts with the stub in login_as.

I have experimented with adding .with() to each one, hoping that 
multiple stubs would be created, but that does not seem to be the case. 
Is there a way to stub the same method but have it return different 
values? Or can someone suggest a better way of handling this situation?

Peace,
Phillip

Two ways to do it: 

1 is documented here; http://rspec.info/documentation/mocks/stubs.html

The other:

User.stub(:find_by_id) do |id|
  if id == $admin_id
    admin_user
  else
    non_admin_user
  end
end

or some such.

To answer my own question, I discovered I could stub @controller in 
login_as:

@controller.stub(:current_user).and_return(user)

which works. Can anyone think of a reason I would not want to do that?
