How to reset non-looping animation in animator?

This seems like an awfully simple question but I've googled extensively.

I have a non-looping animation that gets played once and just pauses at the end of the animation. When the object disables and re-enables, I want to be able to replay this non-looping animation from scratch from a function call. But problem is when I re-enable this object, the animation is still stuck in the last frame even before I can call Play() again.

So far googling has only brought up doing something like this when I re-enable the object

Code (CSharp):

1.  
2. private void OnEnable()
3.     {
4.         spinningAnimator.Play("spinning", -1, 0);
5.         spinningAnimator.speed = 0;
6.     }
7.  

and then set animator speed to 1 when I want the animation to start playing.

Is this the only way?! Surely there's something more elegant to simply reset the "playhead" for a specific animation clip?

 

I suspect that's the best way you're going to find when using Mecanim. Another option would be to play an idle animation instead of using zero speed, but that would take a bunch more work to set up than a single line of code.

What is it you don't like about that approach?
