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

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?

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.
