    <p>I have a directive representing a person with location attributes that change. I'll like to access all the locations together and plot them on a map using something like the angular-leaflet-directive. How can I access these variables in one place? I think I'm really close to getting it working but I don't know which scope has access to all the directives variables. Here is what I have so far?</p> <p>Index.html</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html ng-app="app"&gt; &lt;head&gt; &lt;meta charset=utf-8 /&gt; &lt;title&gt;&lt;/title&gt; &lt;script src="http://code.jquery.com/jquery-1.10.1.min.js"&gt;&lt;/script&gt; &lt;script src="http://code.angularjs.org/1.2.0-rc.3/angular.min.js"&gt;&lt;/script&gt; &lt;script src="http://code.angularjs.org/1.2.0-rc.3/angular-resource.min.js"&gt;&lt;/script&gt; &lt;script src="http://code.angularjs.org/1.2.0-rc.3/angular-animate.min.js"&gt;&lt;/script&gt; &lt;script src="app.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body ng-controller='MainCtrl'&gt; &lt;a href='' class='btn' ng-click='addPerson()'&gt;Add new person&lt;/a&gt;&lt;Hr&gt; &lt;div id='people'&gt; &lt;person lat="0.0" lng="0.0"&gt;&lt;/person&gt; &lt;person lat="0.0" lng="0.0"&gt;&lt;/person&gt; &lt;person lat="0.0" lng="0.0"&gt;&lt;/person&gt; &lt;/div&gt; &lt;hr&gt; &lt;div class="map"&gt; &lt;!-- this will be a directive representing a map --&gt; How do I access the lat and lon of each directive here? So I can plot them all on a map (which is also a directive ...) &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>App.js</p> <pre><code>var app = angular.module('app', []); app.directive('person', function ($compile, $timeout) { function link ($scope, elem, attrs, ctrl) { $scope.lat = attrs.lat; $scope.lng = attrs.lng; $timeout( function changePosition() { console.log('Changing position ...'); $scope.lat = Math.random() $scope.lng = Math.random() $timeout(changePosition, 2000); }, 2000); } return { restrict: 'E', replace: true, template: "&lt;span&gt;Current Lat={{lat | number:2}}, Lng={{lng | number:2}}&lt;br&gt;&lt;br&gt;&lt;/span&gt;", link : link, scope: {}, } }); app.controller('MainCtrl', function ($scope, $compile) { $scope.addPerson = function() { console.log('Adding new person'); var lat = Math.random() var lng = Math.random() angular.element('#people').append($compile('&lt;person lat="'+lat+'" lng="'+lng+'"&gt;&lt;/person&gt;')($scope)); } }); </code></pre>

    1. COshouldn't "people" array already be in the $scope of MainCtrl and render them with ng-repeat? adding a person would simply be a push in the array, not this $compile/append thing which you should definately get rid of.

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.
