RSpec2: stub a method called by another method

I've a problem with rspec2 and rails 3. A stubbed method is called only if I call it directly, not if it's called by a method of the same class.

This is my model:

class Place < ActiveRecord::Base
  def choose_a_winner_for_attack (p_attack)
     puts "REAL choose_a_winner_for_attack"
    (rand() < p_attack)
  end

  def attacks(attacked_place, attack_deployments)
    ….
    win = choose_a_winner_for_attack(p_attack)
    ….
  end
end

In the spec, after Creating a new place, I stub it:

place.stub!(:choose_a_winner_for_attack).and_return(true)

and then I call:

place.choose_a_winner_for_attack 0

it return always true end I never see the log "REAL choose_a_winner_for_attack".

But if I call:

place.attacks(…)

it call the real method "choose_a_winner_for_attack" (I see the log "REAL choose_a_winner_for_attack").

UPDATE This the code of the spec:

  #Stub Place
  place = @user0.place
  place.stub!(:choose_a_winner_for_attack).and_return(true)
  puts "INSIDE SPEC #{f.object_id} #{f.choose_a_winner_for_attack 0}"
  place.attacks(other_place, deployments)

Here there is the problem, I was expecting the stubbed method is called.

Nope, it works:

class A
  def foo
    "foo"
  end

  def bar
    foo
  end
end

describe A do
  it "stubs methods called from within other methods" do
    a = A.new
    a.stub(:foo).and_return("baz")
    a.foo.should == "baz" # passes
    a.bar.should == "baz" # passes
  end
end
