    <p>I didn't think that this question applied to my situation, but it does: <a href="https://stackoverflow.com/questions/9261191/stubbing-warden-on-controller-tests">Stubbing Warden on Controller Tests</a></p> <p>As it turns out, Warden does not get included into RSpec controller specs, so you need to do some magic to finagle it in.</p> <p><a href="https://stackoverflow.com/users/1222666/kentaro-imai">Kentaro Imai</a>'s <a href="http://kentaroimai.com/articles/1-controller-test-helpers-for-warden" rel="nofollow noreferrer">Controller test helpers for Warden</a> blog post was particularly helpful. Here's how I got it working for RSpec.</p> <p><strong>Step 1:</strong> Create <code>spec/spec_helper/warden.rb</code> and paste in these contents, which Kentaro derived from Devise:</p> <pre><code>module Warden # Warden::Test::ControllerHelpers provides a facility to test controllers in isolation # Most of the code was extracted from Devise's Devise::TestHelpers. module Test module ControllerHelpers def self.included(base) base.class_eval do setup :setup_controller_for_warden, :warden if respond_to?(:setup) end end # Override process to consider warden. def process(*) # Make sure we always return @response, a la ActionController::TestCase::Behavior#process, even if warden interrupts _catch_warden {super} || @response end # We need to setup the environment variables and the response in the controller def setup_controller_for_warden @request.env['action_controller.instance'] = @controller end # Quick access to Warden::Proxy. def warden @warden ||= begin manager = Warden::Manager.new(nil, &amp;Rails.application.config.middleware.detect{|m| m.name == 'Warden::Manager'}.block) @request.env['warden'] = Warden::Proxy.new(@request.env, manager) end end protected # Catch warden continuations and handle like the middleware would. # Returns nil when interrupted, otherwise the normal result of the block. def _catch_warden(&amp;block) result = catch(:warden, &amp;block) if result.is_a?(Hash) &amp;&amp; !warden.custom_failure? &amp;&amp; !@controller.send(:performed?) result[:action] ||= :unauthenticated env = @controller.request.env env['PATH_INFO'] = "/#{result[:action]}" env['warden.options'] = result Warden::Manager._run_callbacks(:before_failure, env, result) status, headers, body = warden.config[:failure_app].call(env).to_a @controller.send :render, :status =&gt; status, :text =&gt; body, :content_type =&gt; headers['Content-Type'], :location =&gt; headers['Location'] nil else result end end end end end </code></pre> <p><strong>Step 2:</strong> In <code>spec/spec_helper.rb</code>, within the <code>RSpec.configure</code> block, add this line to include the new module:</p> <pre><code>config.include Warden::Test::ControllerHelpers, type: :controller </code></pre> <p><strong>Step 3:</strong> To log in a user in a <code>before</code> block, use syntax similar to this:</p> <pre><code>before { warden.set_user FactoryGirl.create(:user) } </code></pre> <p><strong>Step 4:</strong> Make sure that you reference <code>request.env['warden']</code> in your controllers, not <code>env['warden']</code>. The latter will not work in controller specs in the <code>test</code> environment.</p> <p>Hat tip to Kentaro Imai, whom I owe a beer one day (or in another life)!</p>

    1. COI followed these instructions but I get `undefined local variable or method 'warden' for #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_2:`.. I am not sure what I am missing...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
