Ajax post请求似乎可以工作，只是数据没有保存在数据库中

我试图做一个ajax post请求到一个AWS postgreSQL数据库提交表单。jquery脚本似乎可以正确地从表单中提取数据、创建数据对象并查询数据库。但是，当我通过psql连接到AWS实例并运行SELECT * FROM "Users";时，表为空。令人困惑的是，我有其他表运行本质上相同的代码和请求正确地将数据发送到数据库。

HTML/jade (addUser.jade)

extends layout

addUser.js

post request handler (user.js)

当我提交表单

Executing (default): INSERT INTO "Users" ("id","givenName","surName","phoneNumber","email","ownerId","notes","updatedAt","createdAt") VALUES (DEFAULT,'Gandalf','Grey','911','gmail@yahoo.com','6lZinEZNK4n0G60tW21EvE','lorem ipsum dolor','2015-07-07 20:38:45.096 +00:00','2015-07-07 20:38:45.096 +00:00') RETURNING *;

POST /api/users/ 200 2945.195 ms - 1488

psql查询的输出

dbname=> SELECT * FROM "Users";

id | givenName | surName | phoneNumber | email | ownerId | notes | createdAt | updatedAt ----+-----------+---------+-------------+-------+---------+-------+-----------+----------- (0 rows)
