Question

I’m looking for a method to generate a invite code. I would prefer the code not looks like garbled text: JakSj12

But rather more like heroku, using a fun word with 3 numbers.

lightspeed131 or happy124, jetski99

How can I build a method that takes a list of words, maybe 100? and randomly assigns 3 numbers to them?

Thanks

Answer 1

Other answers given here are a bit slow, since they shuffle their lists on every call. Here’s something a bit faster:

def wordwithnumber(words)
   words[rand(words.length)]+(rand(900)+100).to_s()
end

wordwithnumber(["lightspeed", "happy", "jetski"])

This gives you three digits every time, if you want a number from 0 to 999 modify the rand() call accordingly.
