        {
          "admin_notification": [],
          "admin_status": "pending",
          "payment_amount_usd": "1",
          "sp_tx_datetime": "Feb 26, 2021, 12:22 PM",
          "sp_tx_hash": "pi_tx3",
          "sp_tx_status": "succeeded",
          "sp_tx_toAddress": "Admin",
          "tx_admin_dateTime": "-",
          "user_buyplan_days": "7 Days"
        }
      ],
      "user_email": "s@mail.com",
      "user_fName": "Sam",
      "user_id": "user_2304354",
      "user_lName": "Smith",
      "user_password": "Abc@123456",
      "user_type": "user",
      "~version": "CgMBFgA="
    }

在這里，我第一次只想要 2 筆交易而不是接下來的交易。 所以我使用了getQueryResultWithPagination方法，但它不適用於單個 object。 所以我創建了一個CouchDB視圖。

"views": {
    "tx-view": {
      "map": "function (doc) {if(doc.transactions.length > 0) {          emit(doc.transactions); }}"
    },
    "tx-view-2": {
      "map": "function (doc) { if(doc.transactions.length > 0) {      doc.transactions.forEach(function (tag) {    emit(doc.user_id, tag);  });}}"
    }
  },

我可以將此視圖添加到鏈代碼查詢方法中並為其創建事務嗎？ 我該如何解決這個問題？
