That's sensible ways of doing things obviously. The can? approach is very similar to the Canada lib IIRC. I'll probably try some of those.

But the best non-business code I like is the one I don't have to code, commit and maintain.

You don't need voters for the example I wrote earlier though, in fact I don't remember the last time I had to write one.

But I think it's more a functional vs OO discussion and we know how those goes ;)

I can see how #[IsGranted(role)] would work without voters but how would #[IsGranted(post, view)] work without voters? Would it dispatch to the post object? If so, then it is pretty much the same as protocols, yeah.

Follow up question: do you think the above would be helpful as a short-guide on Phoenix?

Yes you're probably right about the voter, I've probably mixed it up with the automatic parameter conversion for routing.

I've done too much Phoenix lately I forgot the rest ;)

About the guide I don't know, maybe a blog post yeah, but there is libs that do all that, maybe there's even too many of them. They are fine but lack the cohesiveness you get with something integrated in a framework.
