In Ruby, how do I find out if a string is not in an array?

Right now I have this code:

partial_update = true if session[:intended_params][:controller] == 'foo'
partial_update = true if session[:intended_params][:controller] == 'bar'
partial_update = true if session[:intended_params][:controller] == 'ding'
partial_update = true if session[:intended_params][:controller] == 'dong'
partial_update = true if session[:intended_params][:controller] == 'up'
partial_update = true if session[:intended_params][:controller] == 'down'
partial_update = true if session[:intended_params][:controller] == 'bing'
# ETC. 

I would like to change this to

array = %w[foo bar ding dong up down bing]
partial_update = true if session[:intended_params][:controller]  == array.any_of_the_possibilites

Is there a good way to do this?

Answer 1

Use the Ruby Array (Enumerable) include? method:

array = %w[foo bar ding dong up down bing]
partial_update = true if array.include?(session[:intended_params][:controller])
