  1. POEmpty Session after Omniauth Twitter Callback
    text
    copied!<p>I'm trying to build an Application that is using the OmniAuth gem, so that Twitter users can login.</p> <p>I followed the steps in the tutorials and i'm pretty sure, that i've done everything right.</p> <p>But on the callback from Twitter i get this infamous error message:</p> <pre><code>NoMethodError You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] </code></pre> <p>After digging deeper in the omniauth gem, i figured out, that in the <code>OAuth#callback_phase</code> the session does not contain any oauth information</p> <pre><code>def callback_phase ::Rails.logger.info "session: #{session.inspect}" ::Rails.logger.info "consumer: #{consumer.inspect}" request_token = ::OAuth::RequestToken.new(consumer, session['oauth'][name.to_s].delete('request_token'), session['oauth'][name.to_s].delete('request_secret')) ... end </code></pre> <p>Log after callback</p> <pre><code>session: {"session_id"=&gt;"190523311f7a63fe796558691b1d4fff"} consumer: #&lt;OAuth::Consumer:0x103735b50 @secret="...", @http=#&lt;Net::HTTP api.twitter.com:443 open=false&gt;, @key="...", @options={:access_token_path=&gt;"/oauth/access_token", :proxy=&gt;nil, :http_method=&gt;:post, :site=&gt;"https://api.twitter.com", :request_token_path=&gt;"/oauth/request_token", :scheme=&gt;:header, :oauth_version=&gt;"1.0", :signature_method=&gt;"HMAC-SHA1", :authorize_path=&gt;"/oauth/authenticate"}&gt; </code></pre> <p>So it looks like the Session content is not filled or gets lost on the way from twitter to omniauth.</p> <p>Does anyone have a idea, what can cause the behavior?</p> <p>My Gemfile:</p> <pre><code>gem 'mongrel', '1.2.0.pre2' gem "rails", "~&gt; 3.0.6" gem "mysql" gem 'omniauth' gem 'settingslogic' # config/application.yml gem 'will_paginate', '~&gt; 3.0.beta' </code></pre> <p>Thanks for your help in advance.</p>
