コレクション結合
db.users.aggregate([
{
$lookup: {
from: "chatstates", // 結合先コレクション名（小文字になることが多い）
localField: "code", // User.code
foreignField: “code", // chatState.code と結合
as: "chatStates" // 結果を配列として格納
}
},
{
$project: {
code: 1,
nickname: 1,
userType: 1,
hostCode: 1,
isLinked: 1,
isDeleted: 1,
chatStates: 1
}
}
]);
