Lithium Community 18.7 Release Notes

SuzieH Nah, I guess you wanted me to just specify the field... the user_context collection can't be queried at all separately:

{
  "status" : "error",
  "message" : "undefined collection: user_context",
  "data" : {
    "type" : "error_data",
    "code" : 602,
    "developer_message" : "",
    "more_info" : ""
  },
  "metadata" : { }
}

plus it would also not provide constraints to use on it, which makes it kinda useless =)... so the initial answer stays valid, same result with specified user_context.is_subscribed field!
