问题 How can I set the default where/sort condition in my SailsJS waterline model? In Rails I would use default scope. 回答1: Sails doesn't support default criteria on a per-model basis, but if you're using blueprint routes you can set default criteria for the route by overriding in your config/routes.js file, for example: "GET /user": { controller: 'user', action: 'find', where: {'deleted': false}, sort: 'age DESC' } This will work even if you don't have a find action defined in your UserController

问题 Goal: Return a list of items that were created between two dates. According to this issue https://github.com/balderdashy/waterline/issues/110 there is no between function just yet. However the work around is the following: User.find({ date: { '>': new Date('2/4/2014'), '<': new Date('2/7/2014') } }).exec(/* ... */); To be more exact, we don't want the hard coded dates above so we read in the input from a form submission like so: start = new Date(req.param('yearStart') + '/' + req.param(

问题 I am starting a project with sails and mysql, and I do'nt know how configurate it to show the queries executed in the console. 回答1: Unfortunately this isn't possible with Sails at this time, although the feature has been requested.

MySQL: Log all queries in mysql MongoDB: MongoDB logging all queries 回答2: The mysql adapter has a debug variable LOG_QUERIES to send all queries to the

问题 So, I'm in the middle of implementing a plugin api for my application, and the plugins can have their own models, imagine this.

问题 I'm using SailsJs v0.11.3 and I want to use Promises to avoid using nested callback but I don't know how to return two objects from one stage ( .then() ) to another one. My code looks like this but I got undefined when trying to print start param on the third .then statement. User.findOneById(userId) .then(function (result) { // #1 return result; }).then( function (result_a) { // #2 console.log('---------------- ' + result_a ); var result_b = User.findOneById(ownerId) .then(function (result)

问题 I'm using Sails.js (0.9.8) and MongoDB (via the sails-mongo adaptor) to create a collection of pages that can be positioned in a tree-view. I would like to store the path of a page in an array of UUIDs My model: module.exports = { schema: true, attributes: { uuid: { type: 'string', unique: true, required: true, uuidv4: true }, name: { type: 'string', required: true, empty: false }, path: { type: 'array', required: true, array: true } } } It works well when I save a 'root' page (the 'path'

问题 When I create my model in sails - waterline the db is autogenerated. The problem is that my primary keys are unsigned int(10) and the external keys are int(11) (with sign). In fact the relationship is only in my models and not in db. A code example is the following: // A user may only have a single pet var User = Waterline.Collection.extend({ identity: 'user', connection: 'local-postgresql', attributes: { firstName: 'string', lastName: 'string', // Add a reference to Pet pet: { model: 'pet' }
