使用sails.js和postgreSQL时出错（使用sails-postgresql模块）

我想问个问题。 我正在开发一个应用程序使用sails.js和PostgreSQL（使用sails-postgresql模块）。 我使用的是我的主键types而不是整数的UUID。 但是当我尝试向我的数据库插入数据时有一些错误。

我的模型UserModel.js

 var uuid = require('node-uuid'); module.exports = { adapter: 'somePostgresqlServer', autoPK: false, migrate: 'safe', attributes: { ID: { primaryKey: true, type: 'string', defaultsTo: function (){ return uuid.v4(); }, unique: true, index: true, uuidv4: true }, username: { type: 'string', required: true, unique: true } } }; 

我在控制器中创buildfunction

 create: function(req, res) { if (!req.param('_username') || !req.param('_newPassword') || !req.param('_confirmPassword') || !req.param('_emailAddress') || !req.param('_firstName') || !req.param('_lastName')) { var errorMessage = ["All field are required to sign up"]; req.session.flash = { err : errorMessage } res.redirect('/login'); return; } if (req.param('_newPassword') != req.param('_confirmPassword')) { var errorMessage = ["New password and confirm password must be same"]; req.session.flash = { err : errorMessage } res.redirect('/login'); return; } UserModel.create({ username: req.param('_username'), encryptedPassword: req.param('_newPassword'), emailAddress: req.param('_emailAddress'), firstName: req.param('_firstName'), lastName: req.param('_lastName') }).exec(function(err,post) { if (err) { return res.error(); } res.redirect('/'); }) res.redirect('/'); } 

错误

我希望你能帮助我。 感谢您的关注 ：）

尝试这个：

模型

  var uuid = require('node-uuid'); module.exports = { adapter: 'somePostgresqlServer', autoPK: false, attributes: { id: { primaryKey : true, type : 'string', defaultsTo : function (){ return uuid.v4(); }, unique : true, index : true }, username: { type : 'string', required : true, unique : true } } }; 

调节器

  create: function(req, res) { var username = req.param('_username'), newPassword = req.param('_newPassword'), confirmPassword = req.param('_confirmPassword'), emailAddress = req.param('_emailAddress'), firstName = req.param('_firstName'), lastName = req.param('_lastName'); if (!(username || newPassword || confirmPassword || emailAddress || firstName || lastName)) { var errorMessage = ["All field are required to sign up"]; req.session.flash = { err : errorMessage } return res.redirect('/login'); } if (newPassword != confirmPassword) { var errorMessage = ["New password and confirm password must be same"]; req.session.flash = { err : errorMessage } return res.redirect('/login'); } UserModel .create({ username : username, encryptedPassword : newPassword, emailAddress : emailAddress, firstName : firstName, lastName : lastName }) .then(function(post) { res.redirect('/'); }) .catch(res.negotiate); } 

1. 在模型定义上，不存在migrate ，这是模型configuration。
2. uuidv4也不是一个有效的属性。
3. 在使用Blueprint API ， id字段是必要的，请在actionUtil中查看actionUtil中的蓝图钩子。
4. res.redirect时不要在控制器末尾调用res.redirect 。 过程中，当查询还没有完成时，会出现竞争状态，您将被redirect。

其实我不确定它是否能解决你的问题，但是你可以试一下，稍后再给出结果。
