我有2種型號回送3 「hasOne」 關係
MerchantModel

},

},

{

}
],

}商戶只有一個用戶 這是我的用戶模型
{
"name": "UserData",
"base": "User",
"public": false,
"options": {
"mysql": {
"table": "tbl_users"
}
},
"properties": {
"user_id": {
"type": "string",
"id": true,
"length": 36,
"defaultFn": "uuidv4",
"dataType": "char"
},
"email": {
"type": "string"
}
},
"validations": [],
"relations": {},
"acls": [
{
"accessType": "*",
"principalType": "ROLE",
"principalId": "$everyone",
"permission": "DENY"
},
{
"accessType": "EXECUTE",
"principalType": "ROLE",
"principalId": "$everyone",
"permission": "ALLOW",
"property": "loginApp"
}
],
"methods": {}
}我想創建一個遠程方法來添加商家和該商家的所有者。這是我目前的遠程方法：
'use strict';
var app = require('../../server/server');
module.exports = function(Obj) {
\t Obj.createMerchant = function(req, cb) {
\t \t //create the merchant
\t \t Obj.beginTransaction({
\t \t \t isolationLevel: Obj.Transaction.READ_COMMITTED
\t \t }, function(err, tx) {
\t \t \t Obj.create([{
\t \t \t \t "merchant_name": req.merchant_name,
\t \t \t \t "email": req.merchant_email
\t \t \t }], {transaction: tx}, function(err, merchant){
\t \t \t \t if (err){
\t \t \t \t \t tx.rollback();
\t \t \t \t \t return cb(err, null);
\t \t \t \t } else {
\t \t \t \t \t Obj.prototype.user.create({
\t \t \t \t \t \t "merchant_id": merchant.merchant_id,
\t \t \t \t \t \t "email": req.email,
\t \t \t \t \t "password": req.password
\t \t \t \t \t }, {transaction: tx}, function(err, user) {
\t \t \t \t \t \t if (err) {
\t \t \t \t \t \t \t tx.rollback();
\t \t \t \t \t \t \t return cb(err, null);
\t \t \t \t \t \t } else {
\t \t \t \t \t \t \t tx.commit(function(err) {
\t \t \t \t \t \t \t \t if (err){
\t \t \t \t \t \t \t \t return cb(err, null);
\t \t \t \t \t \t \t }
\t \t \t \t \t \t \t return cb(null, merchant);
\t \t \t \t \t });
\t \t \t \t \t \t }
\t \t \t \t })
\t \t \t \t }
\t \t \t })
\t \t });
\t };
\t Obj.remoteMethod('createMerchant', {
\t \t description: "Create merchant and it's owner",
\t accepts: [
\t {arg: 'req', type: 'object', http: { source: 'body' }}
\t ],
\t returns: {arg: 'list', type: 'object'},
\t http: {path:'/createMerchant', verb: 'post'}
\t });
};遠程方法返回此錯誤：
{
"error": {
"statusCode": 500,
"name": "Error",
"message": "HasOne relation cannot create more than one instance of UserData"
}
}
不知道如何解決這個問題？非常感謝
