POST (create new item) with nested data

[GonZOO82]

I would like POST with nested data, but don't succeed.

Sample:

{
    "title": "test",
    "cover": {  //ManyToOne connection to MediaItem Entity
        "id": 1 // This MediaItem is exist
    }
}

Response: Update is not allowed for this operation.

but when I update item (PUT) then process is good.

I don't want to use this code:

{
    "title": "test",
    "cover": "/media_item/1"
}

What format are you using (ie Accept header)?

[GonZOO82]

I try application/json and application/ld+json

json --> {"id":1} . --> Update is not allowed for this operation.
ld+json --> {"@id":1} --> Update is not allowed for this operation.

json --> {"@id":1} . --> try run SQL nested data INSERT command
ld+json --> {"id":1} --> try run SQL nested data INSERT command

What works with json-ld:

POST /books

{
  "cover": "/covers/1",
  "title": "foo"
}

About json I'm investigating.

api-platform/api-platform#249 not supported yet with plain IDs.

@soyuka not supported when I POST data, but supported in PUT method?!

if (!$normalization && !isset($context['api_allow_update'])) {
    $context['api_allow_update'] = Request::METHOD_PUT === $request->getMethod();
}

If I PUT data with nested content then it's successful.

I was able to get something like this to work by adding "api_allow_update=true" in my deserialization context.

Example

AppBundle\Entity\Resource:
    attributes:
        normalization_context:
            groups: [ 'resource.read' ]
        denormalization_context:
            api_allow_update: true
            groups: [ 'resource.write' ]

This allowed me to POST in data with full object references when I had embedded objects. It worked for me using JSON, LD+JSON, and HAL+JSON.
