How to pass global variables to do block?

Question

ruby

Get config from file

$app_settings = YAML.load_file("#{File.dirname(__FILE__)}/settings.yml")

then in the class do this

def initialize
    @client = Twitter::REST::Client.new do |config|
      config.consumer_key        = $app_settings[:twitter][:api_key]
      config.consumer_secret     = $app_settings[:twitter][:api_secret]
      config.access_token        = $app_settings[:twitter][:access_token]
      config.access_token_secret = $app_settings[:twitter][:access_token_secret]
    end
  end

but from $app_settings it is not possible to pull out the values. How do you transfer them all?

Answer 1

In what class? What do you get? How can you not get it out?
See what's in the variable. Perhaps it is initialized later than the twitter client. Perhaps there is a different structure. Perhaps you need to specify strings instead of characters as keys

Answer 2

Alternatively, the problem may be in scope. When creating an instance of a class, try to write a reference to the variable into some property of the object.

Answer 3

After parsing, keys are strings 99% of the time, unless explicitly set to characters:
$app_settings['twitter']['api_key'] - should be like this
