How to render partial only on production build?

Question

I'm injecting Google Analytics script with partial inside layout. Something like that:

...
= partial "analytics"
...

And analytics.slim including this:

javascript:
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']...

Obvious solution is:

- if environment == 'production'
  = partial 'analytics'

But is doesn't work. Is it possible implement this somehow?

- if build?
