Deprecated render nothing

- [Voiceover] Another change in Ruby on Rails five…is that render nothing has been deprecated.…Here's what I'm talking about.…It was possible before in your controller…to simply render nothing at times.…So, for example, if we have an authorized user…we would render a page to them,…but otherwise, we might render nothing.…We did that with render nothing true.…When you do it this way,…it's not actually rendering nothing.…It's still sending an html header with the status code…letting the browser know that the request…was answered successfully.…

That's the effect that we probably want,…but it isn't entirely clear from what you see…in the code that that's what's happening.…And therefore, it's been decided that…it's much better to use the head method,…which returns an html header with whatever…status code or options that you set,…but which has an empty body.…They do the same thing,…but the second one makes it clear what's happening.…For this reason, using render nothing true…in Rails five will still work,…but you'll also get a deprecation warning…
