06:13 <FromGitter> <Hansterdam> I can use some help around the Union types and how to get rid of that. So, I'm retrieving an object from the DB with granite using <Class>.find :id. Then I want to toggle a value on that and save it again. But, since it's of a type <Class> | Nil, I cannot just do that. But how do I get rid of the Nil? If I wrap it in an if statement with .not_nil! or != Nil or <Object>.class == <Class>. Nothing gets rid of the

06:13 <FromGitter> ... union and it still throws compile errors. I could of course create two functions and overload them for <Class> and Nil, but if I keep doing that I'm just getting a big bunch of Nil functions that do nothing... Far from ideal. How to solve this?

07:08 <FromGitter> <Hansterdam> Sorry for that !<Class>.nil? does seem to work

12:20 <FromGitter> <Blacksmoke16> you can use `.find!` to raise on nil so that crystal knows it cannot be nil

15:21 <FromGitter> <Hansterdam> @Blacksmoke16 Ah, thanks! That was what I was looking for :)

15:22 <FromGitter> <Hansterdam> @robacarp 😁

15:22 <FromGitter> <Blacksmoke16> np, but yea as robacarp said, make sure you handle when an id isnt found

22:13 <FromGitter> <Thellior> @Hansterdam There is also destroy! update! save! methods :)

22:16 <FromGitter> <Thellior> Someone knows how to create a macro variable? ⏎ I tried ⏎ ⏎ ```code paste, see link``` [https://gitter.im/amberframework/amber?at=5b7c8f23f86b741b05a463af]

22:46 <robacarp> @thellior, for non-output macro work, use {% and %} instead of {{ }}, similar to liquid
