Restangular and HATEOAS API - angularjs

Question

I use Spring Boot application and #RepositoryRestResource to implement my REST API. For Project entity I got the following output:
{
"_embedded" : {
"projects" : [ {
"name" : "Test project",
"createDate" : "2016-02-13",
"_links" : {
"self" : {
"href" : "http://localhost:8080/projects/1"
},
"project" : {
"href" : "http://localhost:8080/projects/1"
},
"tasks" : {
"href" : "http://localhost:8080/projects/1/tasks"
}
}
} ]
},
"_links" : {
"self" : {
"href" : "http://localhost:8080/projects"
},
"profile" : {
"href" : "http://localhost:8080/profile/projects"
}
}
}
As we have resource self link instead of database identity it becomes a question how to make navigation between states correctly. I had the following setup before:
app.config(function ($stateProvider) {
$stateProvider.state('projects', {
url: '/projects',
templateUrl: 'partials/projects.html',
controller: 'ProjectListController'
}).state('project', {
url: '/project/:id',
templateUrl: 'partials/project-view.html',
controller: 'ProjectViewController'
...
and to open project info page I passed id to the state.go({id:project.id}) or from ui-sref or open URL: http://localhost:8080/index.html#/projects/1
Now I pass _self.href as hidden param to state function
app.config(function ($stateProvider) {
$stateProvider.state('projects', {
url: '/projects',
templateUrl: 'partials/projects.html',
controller: 'ProjectListController'
}).state('viewProject', {
url: '/project',
templateUrl: 'partials/project-view.html',
controller: 'ProjectViewController',
params: {'href':null}
...
And it works. But as the URL doesn't contain id I could not open project info page using old link: http://localhost:8080/index.html#/projects/1
I've seen a lot of examples but niether one helped as most of them has one state only.
Thanks in advance.
