Question

I’d like to do something like this, where based on some condition I decide whether to set a val to another or to increment it. I feel like I’m missing something obvious here, but how would I make this work?

process_wager(@wagers[@street.current][@action.abbrev])
process_wager(@wagers[@street.current][:total])
process_wager(@actions[@action.abbrev])
process_wager(@wagered)

def process_wager val
    @condition ? val = @amt : val += @amt
end

I know I could do

@wagers[@street.current][@action.abbrev] = process_wager(@wagers[@street.current][@action.abbrev])

but I am hoping for a tidier way like up above.

Answer 1

Why not:

val = @condition ? @amt : val + @amt
