How to pass an object into a state using UI-router?

How to pass an object into a state using UI-router?

I’d like to be able to transition to a state and a pass an arbitrary object using ui-router.
I’m aware that usually $stateParams is used, but I believe this value is inserted into the URL, and I don’t want users to be able to bookmark this data.
I’d like to do something like this.
$state.transitionTo(‘newState’, {myObj: {foo: ‘bar’}});

function myCtrl($stateParams) {
console.log($stateParams.myObj); // -> {foo: ‘bar’}
};

Is there a way to do this without encoding values into the URL?

Solutions/Answers:

Solution 1:

In version 0.2.13, You should be able to pass objects into $state.go,

$state.go('myState', {myParam: {some: 'thing'}})

$stateProvider.state('myState', {
                url: '/myState/{myParam:json}',
                params: {myParam: null}, ...

and then access the parameter in your controller.

$stateParams.myParam //should be {some: 'thing'}

myParam will not show up in the URL.

See the comment by christopherthielen https://github.com/angular-ui/ui-router/issues/983, reproduced here for convenience:

christopherthielen: Yes, this should be working now in 0.2.13.

.state(‘foo’, { url: ‘/foo/:param1?param2’, params: { param3:
null } // null is the default value });

$state.go(‘foo’, { param1: ‘bar’, param2: ‘baz’, param3: { id: 35,
name: ‘what’ } });

$stateParams in ‘foo’ is now { param1: ‘bar’, param2: ‘baz’, param3: {
id: 35, name: ‘what’ } }

url is /foo/bar?param2=baz.

Solution 2:

There are two parts of this problem

1) using a parameter that would not alter an url (using params property):

$stateProvider
    .state('login', {
        params: [
            'toStateName',
            'toParamsJson'
        ],
        templateUrl: 'partials/login/Login.html'
    })

2) passing an object as parameter:
Well, there is no direct way how to do it now, as every parameter is converted to string (EDIT: since 0.2.13, this is no longer true – you can use objects directly), but you can workaround it by creating the string on your own

toParamsJson = JSON.stringify(toStateParams);

and in target controller deserialize the object again

originalParams = JSON.parse($stateParams.toParamsJson);

Solution 3:

Actually you can do this.

$state.go("state-name", {param-name: param-value}, {location: false, inherit: false});

This is the official documentation about options in state.go

Everything is described there and as you can see this is the way to be done.

Solution 4:

Btw you can also use the ui-sref attribute in your templates to pass objects

ui-sref="myState({ myParam: myObject })"

Solution 5:

1)

$stateProvider
        .state('app.example1', {
                url: '/example',
                views: {
                    'menuContent': {
                        templateUrl: 'templates/example.html',
                        controller: 'ExampleCtrl'
                    }
                }
            })
            .state('app.example2', {
                url: '/example2/:object',
                views: {
                    'menuContent': {
                        templateUrl: 'templates/example2.html',
                        controller: 'Example2Ctrl'
                    }
                }
            })

2)

.controller('ExampleCtrl', function ($state, $scope, UserService) {


        $scope.goExample2 = function (obj) {

            $state.go("app.example2", {object: JSON.stringify(obj)});
        }

    })
    .controller('Example2Ctrl', function ($state, $scope, $stateParams) {

        console.log(JSON.parse($state.params.object));


    })

Solution 6:

No, the URL will always be updated when params are passed to transitionTo.

This happens on state.js:698 in ui-router.
