Dear all,
I know that variables that starts with $$ are exclude from serialization,
I'd like to use them for some properties.
My REST API have HATEOAS enabled, so when I get a resource I can easily
resolve some associations.
My idea is to transform
{
"id":1234,
"name":"War and peace",
links : [{"rel":"author", "href":"http://api.acme.com/authors/123"}]
}
into
{
"id":1234,
"name":"War and peace",
"$$author":{"name":"Leon Tolstoi" /*other properties*/}
}
I don't want the author to be send in a REST PUT request because the
deserialisation would fails (there is no "author" property in the scala
object on the server side), so I added $$ and it works.
But is it an official feature or a hack ? The doc says "*Properties with
leading $$ characters will be stripped since angular uses this notation
internally.*", something between "don't use $$ notation" and "use $$
notation if you don't want a field to be serialized".
It seems quite reliable because I don't think AngularJS team will not stop
using $$ soon for internal variable that are not meant to be serialized,
but if it is an official feature it would be even better.
Many thanks,
- A
