SailsJS：神秘的空值

我的问题是，每当一个新的客户端被创build，所有的值在数据库中的空，除了ID，名称，responsable和标志。 我不认为我做了编程错误，所以我认为这是一个callback比赛的情况，但我不能find解决scheme。 PS：只有当我select并发送要上传的图像文件时，才会出现问题，而在另一种情况下，客户端值正确存储。 PS 2：问题只发生在我的远程服务器上，在本地环境中一切正常！

比你非常！

更新：我包含了我的create.ejs视图的代码

这是我的ClientService中的存储方法的代码：

store: function(req, done) { var name = req.param('name'), town = req.param('town'), adress = req.param('adress'), postalCode = req.param('postalCode'), telephone = req.param('telephone'), email = req.param('email'), fax = req.param('fax'), responsable = req.param('responsable'), website = req.param('website'), activity = req.param('activity'); comments = req.param('comments'); Client.create({ name: name, town: town, adress: adress, postalCode: postalCode, telephone: telephone, fax: fax, responsable: responsable, website: website, activity: activity, email: email, comments: comments }).exec(function(err, client) { if (err) console.log(err); req.file('logo').upload( { dirname: sails.config.appPath + sails.config.params.logos }, function(err, logo) { if (err) return done(err, null); if (logo.length !== 0) { client.logo = require('path').basename(logo[0].fd); } else { client.logo = 'default.png'; } client.save(function(err) { return done(null, client); }); } ); }); } 

这是EJS视图的代码：

Answer 1

没有什么神秘的（：你的问题是你使用req.param而不是req.body

而你的代码应该是这样的：

 const path = require('path'); // somewhere in same module at the top store: (req, done) => { Client .create(req.body) .exec((err, client) => { if(err) { // no need to go further // if You cannot create database record return done(err); } const dirname = path.join(sails.config.appPath, sails.config.params.logos); // safely concatenates paths based on OS req .file('logo') .upload({dirname}, (err, logo) => { if (err) { // we created record (client) // but could not save the file // it should not be a stopper console.error(err); } client.logo = (logo) ? path.basename(logo[0].fd) : 'default.png'; client.save((err) => { if(err) { // just log the error and continue console.error(err); } done(null, client); }); }); }); } 

PS当您将req.body （或任何其他）对象传递给Client.create不必担心对象内容，只需在您的模型文件中定义字段约束，ODM（或ORM）将仅基于约束自动处理validation，从创build空值字段

例：

 module.exports = { attributes: { name: { // it requires field name: // to be defined (required: true), // to be string (type), // to have at least 2 symbols, // to not exceed 100 symbols type: 'string', required: true, minLength: 2, maxLength: 100 }, email: { // it requires field email: // to be defined (required: true), // to be email (type), // to be unique among documents, records, rows type: 'email', required: true, unique: true }, ... and so on ... } }

谢谢大家。 我通过将文件input放在表单的末尾来解决问题。 就像你所build议的那样，在file upload之后，文件input后的值被重置
