Deeply nested HABTM doesn't show in 0.10.0.rc3

[nadeemja]

Hi,

I have the following associations between three models:

Event has_many Schedules.
Schedule has_and_belongs_to_many Rooms

In 0.8.3, I get what i want:

-Event
-- Schedules:
---- Rooms:

In 0.10.0.rc3, I only get:

-Event
-- Schedules

I've downgraded to 0.8.3 for now.
Let me know if you need more info.

Hi there!

can you show us your serializer? and controller action where you are rendering the data?

Hi @nadeemja, in 0.10, the default is currently to serialize only the first level of relatinoships (this is being discussed here #1205). You can override this behavior either at the controller level, by specifying the include: '**' option in your render call (like render json: @posts, include: '**'), as soon to be mentioned in the docs (there's a pending PR to add this to the docs), or globally by subclassing ActiveModel::Serializer and overriding serializable_hash.

I'd be careful with '**' though. If you know exactly what associations you want, I think it would be safer to specify those.

@beauby also has a pending PR where you can specify nested relationships in the serializers. see #1193

Closing this for now. Feel free to reopen if needed.
