How to make a writable nested relationship?

[YetAnotherWebDeveloper]

If I do something similar to this https://www.django-rest-framework.org/api-guide/serializers/#writable-nested-representations,

using the following Serializer:

class TestSerializer(serializers.ModelSerializer):
    profile = ProfileSerializer()

class Meta:
    model = Test

It expects my data to be structured like this:

...
"relationships": {
                    "profile": {
                        "data": {
                                "first_name": "John",
                                "last_name": "Test"
                        }
                    }
                }
...

instead of like this:

...
"relationships": {
                    "profile": {
                        "data": {
                            "type": "Profile",
                            "attributes": {
                                "first_name": "John",
                                "last_name": "Test"
                            }
                        }
                    }
                }
...

could someone explain how to make a writable nested relationship with valid JSON:API schema?

Take a look at the json:api specs. Both examples are not json:api specific.

Nested creation is not a well supported thing in json:api. Only creating single resources is covered by the specs.

Maybe atomic operations would be help you to create resources in a single transaction. But this extension is not implemented in this package.

Here is a first alpha version for an atomic operations extension. Maybe this could help you a bit.

Thanks for the info! I'll follow the atomic operations implementation, but I think I'll go for some extra post requests in the short term.
