POHandeling an async call before transitioning to a new route

Body
copied!<p>I want to get the users Geolocation. Once I get the coordinates, I want to load Records based on that Geolocation. If there is more than 1 result, show an index page, </p> <pre><code>LHW.Store = DS.Store.extend revision: 11 adapter: DS.RESTAdapter DS.RESTAdapter.reopen namespace: 'api' LHW.Company = DS.Model.extend name: DS.attr 'string' address: DS.attr 'string' city: DS.attr 'string' LHW.IndexRoute = Ember.Route.extend setupController: (controller, route) -> # get Geolocation _route = @ navigator.geolocation.getCurrentPosition ((location) -> #success _route.geoLocation(location) ), (error) -> #error switch(error.code) when error.PERMISSION_DENIED then console.log "User denied the request for Geolocation." when error.POSITION_UNAVAILABLE then console.log "Location information is unavailable." when error.TIMEOUT then console.log "The request to get user location timed out." when error.UNKNOWN_ERROR then console.log "An unknown error occurred." geoLocation: (location) -> _route = @ @get('store').findQuery('company',{longitude: location.coords.longitude, latitude: location.coords.latitude}).then ((data) => _route.controllerFor('companies').set('content', data) if data.get('length') > 1 _route.transitionTo('companies'); ), (error) -> console.log "error" LHW.CompaniesRoute = Ember.Route.extend() LHW.IndexController = Ember.ArrayController.extend beforeModel: -> console.log 'before' </code></pre> <p>So this is what I got now. But this has a few problems</p> <ol> <li>If you go to /companies instead of / It skips the geolocation check. But if I move the geolocation to the companies route, then what is the page the users sees while geolocation is getting fetched? </li> <li>Creating a switch and checking the length in a route, feels a bit dirty, imo the Companyroute should respond to that</li> </ol> <p>So this is mostly a flow issue I can't wrap my head around and the async geolocation isn't making things easier...</p>

Querying!
