REST Models and Relationships

Question

Angular

Hello, show an example of a correct model with connections.
For example, there are orders and services for these orders
Models Order, Service (the same is on the server, there is a third OrderServices to connect these models)
According to the REST principle, to add service 8 to order 3, what needs to be done?
If you write like this:
POST /orders/3/services/8
That means changing service 8 for service 3.

What if you need to add a comment to service 8 for order 3?

If you just need to change the state on off again POST / orders / 3 do?

how is it done in AngularJS?

Answer 1

One hassle with these nested addresses, it's much easier for each resource to have its own entry point.
AngularJS has a special $resource for working with REST.
If it doesn't work with $resource, you can use regular $http.

Answer 2

And now how to register all this in the AngularJS model?
$resource('/api/orders/:orderId/:action/:serviceID', ...)
right?

Answer 3

POST /orders/3/services {serviceId: 8}, it seems. And for change - PATCH.
