    <p>I have been following the <a href="http://andrzejonsoftware.blogspot.com/2007/05/15-tdd-steps-to-create-rails.html" rel="noreferrer" title="15 TDD steps to create a Rails application">15 TDD steps to create a Rails application</a> guide - but have run into an issue I cannot seem to resolve. For the functional test of the WordsController, I have the following code:</p> <pre><code>class WordsControllerTest &lt; ActionController::TestCase test "should get learn" do get 'learn' assert_response :success end test "learn passes a random word" do some_word = Word.new Word.expects(:random).returns(some_word) get 'learn' assert_equal some_word, assigns('word') end end </code></pre> <p>In the Word class I have the following code:</p> <pre><code>class Word &lt; ActiveRecord::Base def self.random all = Word.find :all all[rand(all.size)] end end </code></pre> <p>When I run the tests, I experience the following error (shortened for brevity):</p> <pre><code>1) Failure: unexpected invocation: Word(...).random() satisfied expectations: - expected exactly once, already invoked once: Word(...).random() </code></pre> <p>I have tried changing changing the order of the tests along with a multitude of other things, but time and time again I continue to receive the same test failure - that Word.random() has already been invoked. </p> <p>I'm running Rails 3.0 beta 4 and Mocha 0.9.8. I've searched long and hard for a solution to my problem, but I can't seem to find it. I'm new to Ruby/Rails so am rather unfamiliar with the language and the frameworks.</p> <p>Thanks in advance!</p>

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.
