create templated link from param keys

[schroedan]

This will add the params (if specified) on non-templated links.

Is this part of the HAL- standard?

[schroedan]

I believe this is not part of the HAL spec. It just enables the hrefLink method to append the provided query params on non-templated links. Otherwise they would get lost.

@pCoLaSD nice try. I suppose you just want to append some dynamic stuff like filtering by resource properties. However you PR restricts that only plain query params can be dynamically appended. Moreover you can't mix hash params, defined params with dynamic params or path parameters like the one below.

I would recommend to use what is already in spec and implemented by rfc6570.js. As an example, run the following line in the browser console on a page with angular-hal.js loaded:

new rfc6570.UriTemplate("http://localhost/api/{bucket}/items{?sort,filters*}").
    stringify({
        bucket: 'stuff',
        filters: {type: 'music', author: 'davidbowie'},
        sort:'created_at'});

Result: "http://localhost/api/stuff/items?sort=created_at&type=music&author=davidbowie"

Read the spec, there are even more cool use cases: http://tools.ietf.org/html/rfc6570

@pgaertig thank you for this advice. The actual problem I have ist that my PHP backends (implemented with Zend Framework 2 and some Apigility magic) can't handle templated links. In consequence I can't "stringify" those links out of the box in my app.
I think it will be a better approach to teach Apigility to handle templated links instead of this litte hack here.
Thanks anyway!
