Angular ui-router get asynchronous data with resolve

Question

I want to display a form with data corresponding to the edited item. I use ui-router for routing. I defined a state:

myapp.config(function($stateProvider) {

    $stateProvider.
    .state('layout.propertyedit', {
        url: "/properties/:propertyId",
        views : {
            "contentView@": {
                templateUrl : 'partials/content2.html', 
                controller: 'PropertyController'
            }
        }
    });

In PropertyController, I want to set $scope.property with data coming from the following call (Google Cloud Endpoints):

    gapi.client.realestate.get(propertyId).execute(function(resp) {
        console.log(resp);
    });

I don't know if I can use resolve because the data are returned asynchronously. I tried

    resolve: {
        propertyData: function() {
            return gapi.client.realestate.get(propertyId).execute(function(resp) {
                console.log(resp);
            });
        }
    }

First issue, the propertyId is undefined. How do you get the propertyId from the url: "/properties/:propertyId"?

Basically I want to set $scope.property in PropertyController to the resp object returned by the async call.

EDIT:

myapp.controller('PropertyController', function($scope, , $stateParams, $q) {

    $scope.property = {};

    $scope.create = function(property) {
    }

    $scope.update = function(property) {
    }

function loadData() {
    var deferred = $q.defer();

    gapi.client.realestate.get({'id': '11'}).execute(function(resp) {
        deferred.resolve(resp);
    });

    $scope.property = deferred.promise;
}

});

You need to read the docs for resolve. Resolve functions are injectable, and you can use $stateParams to get the correct value from your routes, like so:

resolve: {
    propertyData: function($stateParams, $q) {
        // The gapi.client.realestate object should really be wrapped in an
        // injectable service for testability...

        var deferred = $q.defer();

        gapi.client.realestate.get($stateParams.propertyId).execute(function(r) {
            deferred.resolve(r);
        });
        return deferred.promise;
    }
}

Finally, the values for resolve functions are injectable in your controller once resolved:

myapp.controller('PropertyController', function($scope, propertyData) {

    $scope.property = propertyData;

});
