Rails 3 If Statement,,, IF XXX Equals At Least One (Var1, Var2, Var3)

Question

Is the following statement possible with Rails/Ruby? If so, how :)

IF XXX Equals At Least One (Var1, Var2, Var3)

Answer 1

if [a, b, c].find_index(XXX)

Sounds simple enough. And there's nothing wrong with classical way too:

if XXX == a || XXX == b || XXX == c

Answer 2

Try this:

if [v1, v2, v3].any?{|v| v=="XXX"}
 p "Success"
end

OR

if [v1, v2, v3].include?("XXX")
 p "Success"
end
