ruby on rails - Trouble Getting Twitter Gem To Work - Giving Undefined Method Errors -

i following along documentation twitter gem , trying results, getting following error:

undefined method `sample' nil:nilclass 

i've put in config/initializers/twitter_credentials.rb (my keys , tokens filled in app)

@client = twitter::streaming::client.new |config|   config.consumer_key        = "your_consumer_key"   config.consumer_secret     = "your_consumer_secret"   config.access_token        = "your_access_token"   config.access_token_secret = "your_access_secret" end 

here bits controller:

require 'twitter'  class staticpagescontroller < applicationcontroller   def home     @tweets = array.new     @client.sample |object|         @tweets << object.text if object.is_a?(twitter::tweet)     end   end end 

this in view:

<% @tweets |tweet| %>    <%= tweet.text %> <% end %> 

and of course, in gemfile:

gem 'twitter' 

why getting error?

the problem was referencing using instance variable (e.g. @client = ), when needed make constant or global.

answer client =

the other option put instantiate client within controller.
