Getting joined data for widget scope

Ya, I have it in the public_user_custom_fields site setting as well. Perhaps I am misunderstanding userCustomFields. The field in question is created under customization > user fields and the user can fill it in under their preferences.

In the rails console, UserCustomField gives me:

#<UserCustomField:0x007fb6a2bed830
  id: 10,
  user_id: -1,
  name: "user_field_2",
  value: "Cold Lake",
  created_at: Thu, 28 Apr 2016 18:03:11 UTC +00:00,
  updated_at: Thu, 28 Apr 2016 18:03:11 UTC +00:00>

So maybe I need to add “user_field_2” to the site settings rather than the name of the field?
