问题 It's clear how to access the new values, the first argument contains them beforeUpdate: function (values, cb) {....} But how can I access the current values, that are to be replaced? 回答1: In order do access current values you will have to make the call and get the current record. models/user.js beforeCreate: function (values, cb) { User.findOne(this.update.arguments[0].id || this.update.arguments[0]).exec(err, function(originalUser){/*...*/}) } Also check out https://github.com/balderdashy

问题 I have the following model, let's say it describes a book: module.exports = { attributes: { name: { type: 'String', required: true }, type: { type: 'string', required: true }, book_id: { type: 'integer' } } } Here the 'type' attribute is the genre of the book, for example HorrorBook. I have a separate model for HorrorBooks, FantasyBooks and such, since the structure of the models differs from each other so much, they have fields the other doesn't have etc, which is why I can't just use a

问题 I know it's pretty easy and possible to listen to a unix socket file in express mvc. But in sailsjs, I do not know where and how to do this due to lack of documentation. 回答1: If you're referring to the ability of Express to bind to a Unix domain socket rather than a port, you can accomplish the same with Sails by setting the port config, either on Sails lift: sails lift --port=/tmp/sails.sock or in your /config/local.js port: '/tmp/sails.sock' Then you could telnet /tmp/sails.sock with Sails

问题 I am trying to develop an API backend in Sails.js. The most basic thing which I require is authentication. With that, I found the sails-generate-auth generator, I have followed all the steps listed at sails-generate-auth . Now, when I access http://localhost:1337/register , I see a simple registration form, same goes for login, and after logging in, I see a cookie set in my browser as sails.sid . After inspecting the AuthController.js I see that it has been written for server rendered views.

问题 Situation: Upgrading an old site that was basic HTML to use SailsJS. Old site has .html extensions and is ranked well in search engines for these results. As such I would like to route all incoming requests from their old URLs (.html extension) to their new results generated via sails (no extension). The best approach seems to be a 301 redirect but I am unsure as the best practices to implement this using a SailsJS based server. www.blah.com/blah2.xml => www.blah.com/blah2. 回答1: You should

Thank you! connection: 'postgres', tableName: 'user__c', meta: { schemaName: 'sales' }, attributes: { name: { type: 'string' }, picture_url: { type: 'string' } } 回答1: It's been so long but still, this is still an issue with waterline-sequel (0.5.0) in the latest version of Sails (0.11.x), and it has

问题 If socket is disconnected from the server, Will all the subscription of that socket will be removed from the chat-room by default(by sails) or we have to remove it manually(by code) 回答1: Base of socket.io source code this.leaveAll() will run before fire disconnect event. So no need to leave from rooms manually Socket.prototype.onclose = function(reason){ if (!this.connected) return this; debug('closing socket - reason %s', reason); this.emit('disconnecting', reason); this.leaveAll(); // leave

问题 I have been trying to implement rememberme functionality using sails. I want a session to persist until the browser is closed. However, if a rememberme checkbox is ticked when the user logins in I want the session to persist for 30 days. I used the remember me passport strategy from here: https://github.com/jaredhanson/passport-remember-me but it ends up sitting on top of the sails session and the one called first ends up superseding the other. 回答1: You can set the cookie age just before

问题 I am using sails version 0.11 which comes bundled with skipper for file uploads. I need to upload big files of over 100 MB in size at least.

Here is how I am trying to achieve the same: var csv = require("fast-csv"); bulk: function (req, res){ function parseEntry(entry){ return entry } var inputStream = req.file('employees'); var
