remear:
just so i understand, the adapter in `render json: resource, status: 422, adapter: 'json_api/error',
serializer: ActiveModel::Serializer::ErrorSerializer` is a different one than, say what i’ve
specified in a base serializer with `ActiveModel::Serializer.config.adapter = :json_api`. correct?
and a followup question of, why not same adapter but different serializer?
me:
With the way the code is written now, it might be possible to not require a special jsonapi adapter.
However, the behavior is pretty different from the jsonapi adapter.
this first draft of the PR had it automatically set the adapter if there were errors. since that
requires more discussion, I took a step back and made it explicit for this PR
If I were to re-use the json api adapter and remove the error one, it think the serializable hash
method would look like
```
def serializable_hash(options = nil)
return { errors: JsonApi::Error.collection_errors } if serializer.is_a?(ErrorsSerializer)
return { errors: JsonApi::Error.resource_errors(serializer) } if serializer.is_a?(ErrorSerializer)
options ||= {}
```
I suppose it could be something more duckish like
```
def serializable_hash(options = nil)
if serializer.errors? # object.errors.any? || object.any? {|o| o.errors.any? }
JsonApi::Error.new(serializer).serializable_hash
else
# etc
```
