    <p>I am considering migrating from backbonejs to angularjs. </p> <p>In backbone I am able to initialize a view at which point I create an instance of google map. I can then pan/zoom/etc and switch between views and not lose the current state of the map.</p> <p>Given the following using angularjs:</p> <p>layout.html</p> <pre><code>&lt;body&gt; &lt;div class="container-fluid" ng-view&gt;&lt;/div&gt; </code></pre> <p>map.html</p> <pre><code>&lt;div id="map_canvas" ng-controller="MapCtrl"&gt;&lt;/div&gt; </code></pre> <p>I was able to create a directive to render a map just fine. Problem is that it reloads the map each time I switch back to the map view.</p> <pre><code>&lt;map&gt;&lt;/map&gt; </code></pre> <p>So from what I am learning about Angular, I figured I would create a MapController and initialize the map there. No success.</p> <p>Bottom line is I need to async-init a google map and push data to it locally or remotely AND be able to navigate the app without RELOADING the map from scratch each time.</p> <p>Can someone suggest the correct approach?</p> <p>Thank you :)</p> <p><strong>Attempt Per Andy Joslin suggestion:</strong></p> <p><strong>In app.js:</strong></p> <pre><code>// Generated by CoffeeScript 1.3.3 (function() { "use strict"; angular.module("ofm", ["ofm.filters", "GoogleMaps", "ofm.directives"]).config([ "$routeProvider", "$locationProvider", function($routeProvider, $locationProvider) { $routeProvider.when("/", { templateUrl: "partials/home" }).when("/map", { templateUrl: "partials/map", controller: MapCtrl }).otherwise({ redirectTo: "/" }); return $locationProvider.html5Mode(true); } ]); }).call(this); </code></pre> <p><strong>In services.js:</strong></p> <pre><code>angular.module('GoogleMaps', []). factory('wasMapInitialized', function() { console.log("inside service"); var maps = 0; if (!maps) { maps += 1; return 0; } else { return 1; } }); </code></pre> <p><strong>In controllers.js:</strong></p> <pre><code>function MapCtrl($scope) { if (!GoogleMaps.wasMapInitialized()) { var lat = 46.87916; var lng = -3.32910; var map_id = '#map'; initialize(map_id, lat, lng); } function initialize(map_id, lat, lng) { var myOptions = { zoom : 8, center : new google.maps.LatLng(lat, lng), mapTypeId : google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map($(map_id)[0], myOptions); } } </code></pre> <p><strong>In map.html</strong></p> <pre><code>#map &lt;div ng-controller="MapCtrl"&gt;&lt;/div&gt; </code></pre> <p><strong>I get Error: Unknown provider: GoogleMapsProvider &lt;- GoogleMaps</strong></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.

SQuiL has stopped working due to an internal error.

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