Support of HAL format

[konstlepa]

Hi.

I'm trying to add support of HAL. I read #42 and #44. But I still have many questions. I've made a first attempt to adapt Restangular. Please, see the commit with my comments: https://github.com/KonstantinLepa/restangular/commit/5b71894aa149de807dbafd5afc5e9256e6e181e8. It doesn't work correctly now.

There are my problems:

• Processing of _embedded property. It's optimization only. It can exist or not exist. It must be transparent to the client. How should I implement it?
• Chaining of methods. For example, messages, from and unread for $scope.user.one('messages', 123).one('from', 123).getList('unread'); are relations. They are not parts of URL. What will happen if from relation doesn't exist in a data? I think one('from', 123) must return an empty restangular object. Or not?

Thanks

P.S. Also, HAL supports the CURIE syntax http://tools.ietf.org/html/draft-kelly-json-hal-06#section-8.2. But I didn't think about it.

Hey,

Using selfLink and allUrl and oneUrl I've tried to support all of the similar HyperMedia formats.

Could you give me exact examples of how your response your formed and what you don't know how you'd support with Restangular?

Thanks!

Hi. I wrote own implementation of HAL client. It could be helpful for you.

Hey,

Can any of you give me an example of a HAL response that is currently not supported in Restangular?

Thanks!

Here's another made up example:

  "_links" : {
    "self" : {
      "href" : "/api/sources"
    }

  "_embedded" : {

      "_links" : {
        "self" : {

Another example:

git clone git@github.com:spring-projects/spring-boot.git
cd spring-boot/spring-boot-samples/spring-boot-sample-data-rest
mvn spring-boot:run
then http://localhost:8080/hotels
