Trouble Getting Twitter Gem To Work - Giving Undefined Method Errors

Question

I am following along with the documentation for the Twitter gem and trying to get some results, but I am getting the following error:

undefined method `sample' for nil:NilClass

I've put this in my config/initializers/twitter_credentials.rb (my keys and tokens are filled in my app)

@client = Twitter::Streaming::Client.new do |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 are bits from my controller:

require 'twitter'

class StaticPagesController < ApplicationController
  def home
    @tweets = Array.new
    @client.sample do |object|
        @tweets << object.text if object.is_a?(Twitter::Tweet)
    end
  end
end

This is in my view:

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

And of course, this is in my gemfile:

gem 'twitter'

Why am I getting that error?

Answer 1

The problem was that I was referencing it using an instance variable (e.g. @client = ), when I needed to make it a constant or a global.

Answer CLIENT =

The other option was to put it instantiate the client within the controller.

Answer 2

In your controller, 'sample' is not define.

@client.sample do |object|
