Loop until i get correct user


Tag: ruby,redis

I have users stored in Redis and want to be able to call only certain subsets from a set, if i don't get the correct user back i want to put it back in the set and then try again until i get one of the desired users

@redis =
@randUser = @redis.spop("users")

if @randUser.include?(["user_4", "user_5", "user_6"])
  @redis.sadd("users", @randUser)
  # Run @randUser = @redis.spop("users") again
  $user_username = @redis.hget(@randUser, "username")
  $user_password = @redis.hget(@randUser, "password")

I cant quite get the logic right in my head, how else could i approach this please?

Any help appreciated



Change if to while:

while ["user_4", "user_5"].include?(@randUser = @redis.spop("users")) do
  @redis.sadd("users", @randUser)

$user_username = @redis.hget(@randUser, "username")
$user_password = @redis.hget(@randUser, "password")

Please note, that you actually mixed up receiver and parameters on Array#include?
