I want to write a method which takes its input and adds it to an array (in this case I am trying to abstract a session item as I think it looks prettier to use a helper method).
For example, native in ruby we have arr:
arr =
arr << ‘item’
Is there a way I can write a method that uses the ‘<<’ syntactic sugar? Been poking around and don’t see clearly how to do this.

def <<(other)
whatever
end
I see, so it has to be within a class and not named… so if I am writing a helper method in app controller then this is weird, but now I see that I need to make a class for what I do, so thanks, my design has improved.

Module, actually. But this shouldn't surprise you: it's just a method
like any other.

It is named. Its name is :<< .

Yeah. Don't put logic in your controllers. And remember that you can
reopen or mix into existing classes.
