Continuing the discussion from Getting joined data for widget scope:
I am trying to extend the poster-name widget and add some user custom fields next to a user’s name on a post.
As per @eviltrout:
and…
whitelist_staff_user_custom_field("myCustomField") in plugin.rb 
I have whitelisted the custom field I am trying to access but when I view attrs.userCustomFields of the poster-name widget it is undefined. Am I missing a step to make the user custom fields available to the widget/plugin?
If things haven’t changed, you need to add user custom fields to the post serializer when you want a user custom field on the post object.
Like this:

I was going off the Discourse Staff Notes plugin which uses the poster-name widget in a similar way I want to, and it doesn’t look like they do that.
Os campos personalizados do pôster estão vazios quando um novo pôster é criado. Usando o método allow_public_user_custom_field para permitir campos de usuário.
