    <p>Your problem is that your <code>return</code> method doesn't return what you think it does. Your <code>return</code> function returns what <a href="http://api.jquery.com/jQuery.getJSON/" rel="nofollow noreferrer"><code>getJSON</code></a> returns and <code>getJSON</code> is an AJAX call. jQuery's AJAX calls all return <a href="http://api.jquery.com/Types/#jqXHR" rel="nofollow noreferrer"><code>jqXHR</code>s</a> and that has nothing to do with what the AJAX callbacks return. The sequence of events looks something like this:</p> <ol> <li>You call <code>JsonParser.return</code>.</li> <li><code>return</code> calls <code>$.getJSON</code>.</li> <li><code>getJSON</code> makes an asynchronous call to the server and then returns a <code>jqXHR</code>.</li> <li><code>return</code> returns the same <code>jqXHR</code> that <code>getJSON</code> returns.</li> <li>Some time passes.</li> <li>The server gets around to responding and your callback is called to search through the JSON.</li> </ol> <p>The problem is that while <strong>(5)</strong> is happening, the code that called <code>JsonParser.return</code> is still going but it has no JSON.</p> <p>The usual way to get around the asynchronous nature of AJAX calls is to send in a callback function that will get called when something is ready:</p> <pre><code>@return: (json_file_path, string_to_query, callback) -&gt; $.getJSON json_file_path, (data) -&gt; $.each data, (key,val) -&gt; if key == string_to_query callback(val) </code></pre> <p>Then you'd use it like this:</p> <pre><code>JsonParser.return("file.json", "key", (value) -&gt; # Do whatever needs to be done with value in here. ) </code></pre> <p>Now you have something that should work and you can find out how to use Jasmine with it over here:</p> <blockquote> <p><a href="https://stackoverflow.com/q/4662641/479863">How do I verify jQuery AJAX events with Jasmine?</a></p> </blockquote>

    1. COThanks for the response, I am still getting the same result, the json file path I have been using is a local file, not called through a server, is that potentially an issue ?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
