Unmarshal access to "meta"

[mitchellh]

It'd be great to have access to an annotation type "meta" or some other way to easily access the Meta information from a JSON API document.

Currently I'm unmarshaling twice: once into OnePayload via encoding/json and again via the jsonapi unmarshal methods. It'd be wonderful to button this up.

The point of meta is to describe the response.. What's the point of submitting a request with meta to your api? If its a required field, it should be in attributes or another object? Not disagreeing, just wondering what the use-case is?

My use case is actually for a response, I'd like to extract that meta result. Currently I'm unmarshaling twice to get it since the tags don't support getting it directly.

Ahhh. Totally get it!!

Hi there. Is there any update on this issue or the related #95 ?

My use-case requires creating a go JSON API server and client, meaning I will need to marshal and unmarshal the data. More specifically, I would like access to the "meta" for a relationship, which seems to be already supported for marshalling (see https://github.com/google/jsonapi/blob/master/node.go#L59).

My current options seem to be:

1. Unmarshal twice, as @mitchellh has done. I believe that this would require a little work to map the data to the appropriate relationship.
2. Unmarshal exclusively using encoding/json.

If anyone has any other potential workarounds, I'd be extremely grateful!

func setDataIntoTarget(data *Data, target interface{}) error {} is missing following chunk of code which will resolve meta part of unmarshaling
if data.Meta != nil {
err = json.Unmarshal(data.Meta, castedTarget)
if err != nil {
return err
}
}
