waterline

问题 I have a find query that returns multiple results of an object, this object contains a model that contains another model, the thing is that waterline doesn't support nested populates, so it populates the first model but not it's inner model. all the examples I've seen for that are for a findOne query, i am looking for a way to resolve that for a find query that returns multiple results. This is my models structure: // Container.js widgets: { model: 'websitewidget' } // WebsiteWidget.js html:

问题 When using the waterline ORM, if I want to consume the bluebird promise api thats shipped by default how to I pass the processing back to the controller. Below is the code : module.exports = { //Authenticate auth: function (req, res) { user = req.allParams(); //Authenticate User.authenticate(user, function (response) { console.log(response); if (response == true) { res.send('Authenticated'); } else { res.send('Failed'); } }); } }; module.exports = { // Attributes // Authenticate a user

问题 while the email validation rule fails on module of the sails.js, the server is crashing. Here the snippet of my module: // The user's email address email: { type: 'string', email: true, required: true, unique: true }, And the error as below : err: Error (E_VALIDATION) :: 1 attribute is invalid at WLValidationError.WLError (C:\Users\yuri\AppData\Roaming\npm\node_modules\sails\node_modules\waterline\lib\waterline\error\WLError.js:26:15) at new WLValidationError (C:\Users\yuri\AppData\Roaming

问题 According to Between Dates using Waterline ORM SailsJS it is possible to do a between query on dates in the Waterline adapter like the following: User.find({ createdAt: { '>': dateFrom, '<': dateTo } }).exec(/* ... */); However, this does only work with date formats like 2018-04-11 . Is it somehow possible to use the full ISO8601 date format in this query: e.g. 2018-04-11T12:45:00.000Z ? EDIT: Added minimal working example code. readDataInDateRange: function(req, res) { var dateFrom = req

问题 Someone know how I could upload a file to a controller action using the (inputs, exists) format of sails.js, this is my try: module.exports = { friendlyName: 'Upload file recording', description: 'Upload a recording to AWS', inputs: { name: { required: true, type: 'string' }, mimeType: { required: true, type: 'string' }, recording: { type: 'ref' } }, exits: { noRecordings: { responseType: 'no recordings', description: `You don't have any recording for this event`, }, serverError: {

问题 I want's to exclude some data in some controller method and in other method i want's that data. I do it with forEach function right into method after finding that : nine: function (req, res) { Dore.find() .limit(9) .sort('createdAt DESC') .populate('file') .exec(function (err, sh) { if (err) { return res.negotiate(err); } else { console.log('before : ', sh); sh.forEach(function (item, i) { delete item.zaman; }); console.log('after : ', sh); return res.send(sh); } }); }, I want to know how

问题 I am using Sails' ORM (Waterline). I have written a geturl service that should return the url of several models/actions in my app. I am currently calling this service inside my templates. (As I am alone to develop this, don't hesitate to warn me if this design pattern is wrong) Now it occurs that Waterline's .find() method is asynchronous (as it should). I always use callbacks to do things when inserting or fetching things in database. Now I have seen everywhere that I cannot return any data

问题 How can I enforce a Model property to be exactly 32 characters long? I have tried key : { type: 'string', len : 32 } but it doesn't work. 回答1: Ok, let me tell you what i did. After reading hours y figure out that "columnType" property is the solution. It works together with "type" property. For example. I have a "description" field. It looks like: descripcion: { type: 'string', columnType: 'varchar (27)' } And it works. (this is for mysql db). I hope this works for you. This is on the docs.

问题 How can I select or update multiple records in oriento? Like in waterline we can offersModel.update({id:items_ids,status:INACTIVE},{status:ACTIVE}) But in waterline transaction is not available. So I want to use : var db = offersModel.getDB(); var trans = db.begin(); trans.update('offers') .set({status:INACTIVE}) .where({id:items_ids,status:ENM.SELLING_STATUS.ACTIVE})//.exec() .then(function(offers){ if (offers.length != items_ids.length) {trans.rollback(); /* send error here*/} else trans

问题 How do I tell my sails model that I want some specific number decimal places for a type: 'float' attribute? Like decimalPlaces: 4 or something of that ilk? The problem is that when i post a value to this entry, the value on disk is truncated to the .00 (hundreds) place. Say I want: 3243.2352362 to be stored just as it is. Currently this is transformed into 3243.24 If it matters I'm using the sails-mysql adapter. 回答1: types: { decimal2: function(number){ return ((number *100)%1 === 0); } },
