Sample Code

// When a user views a record, they are added to the user selection list

(function() {
    'use strict';

    var VIEWEDUSERS = 'user_log'; //field code of user selection field
    var events = ['app.record.detail.show'];

    kintone.events.on(events, function(event) {
        var record = event.record;
        var isRead = false;
        var users = record[VIEWEDUSERS].value;
        var myUserCode = kintone.getLoginUser().code;

        for (var i in users) {
            if (!users.hasOwnProperty(i)) { continue; }
            if (users[i].code === myUserCode) {
                isRead = true;

        if (isRead) { return event; }

        var param = {
            "app": kintone.app.getId(),
            "id": kintone.app.record.getId(),
            "record": {
                [VIEWEDUSERS]: {
                    "value": users.concat({
                        "code": myUserCode
        kintone.api(kintone.api.url('/k/v1/record', true), 'PUT', param).then(function(resp) {
        }).catch(function(error) {


Make sure to match the Field code of your fields, with the Field code written in the code.
