    var loopback = require('loopback');
    var serviceOffering = loopback.getModelByType('ServiceOffering');
    var app = require('../../server/server.js');

    module.exports = function (serviceOffering) {

        serviceOffering.GetAllOfferings = function (options,category,callback) {
            var filter = JSON.parse(JSON.stringify(category));
             var arry=[];
             var getOrgFil={where:{or:[]}};
             var uniqOrList=[];

             serviceOffering.find(options,filter, function (err, result) {
     
               for(var i = 0; i < result.length; i++) {
                    var obj = result[i];
                   if (arry.indexOf(result[i]._createdBy) === -1) {
                     arry.push(obj._createdBy);
                     getOrgFil.where.or.push({UserName:obj._createdBy});
                    }
                }
                console.log(getOrgFil);
                serviceOffering.app.models.Realm.find(options,getOrgFil, function (err, resl) {
                console.log(resl);
                          return callback(null, resl); 
                });

        serviceOffering.remoteMethod(

我打电话给＆＃39; Realm＆＃39;来自我的服务提供商的模型＆＃39;模型的远程方法来过滤和获取一些数据。但我得到的响应是＃34;未定义＆＃34;。我是环回的新手，对如何调试的想法非常有限。我能够打印＆＃34;结果＆＃34;，＆＃34; getOrgFil＆＃34;，但是＆＃34; resp＆＃34;来自＆＃39; undefined＆＃39;。有人可以帮我理解为什么我会得到＆＃39; undefined＆＃39;当我试图通过远程方法获取resp的值？

 I get output as mentioned below   

result = [ { SeriviceCategory: 'SCCER',
             AssetType: List [ 'ATCOF', 'ATHUS', 'ATMLK' ],
             ServiceType: List [ 'STQCR' ],
             Identity: null,
             _type: 'ServiceOffering',
             _createdBy: 'admin',
             _modifiedBy: 'admin',
             _createdOn: 2018-01-01T09:21:48.638Z,
             _modifiedOn: 2018-01-01T09:21:48.638Z,
             _scope: List [ 'tenantId:default' ],
             _autoScope: { tenantId: 'default' },
             _isDeleted: false,
             _version: '536c3db2-2323-4004-afb6-2a9e7995aeca',
            id: 5a49fdac28a2bd802d8206ba } ]

getOrgFil =  { where: { or: [ [Object] ] } }
stringified getOrgFil =  {"where":{"or":[{"UserName":"admin"}]}}

resl =   undefined

将是这个

<script type="text/javascript">
    function change(el) {
        if (el.value === "P")
            el.value = "A";
        else
            el.value = "P";
    }
</script>

从远程方法访问另一个环回模型的数据时返回未定义？
