waterline

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 from asynchronous methods. As a consequence I am puzzled because I want to create this [damned] service

Using Sails.js version 0.10.x , assume I have a model Dog , populated as follows (writtenout in yaml format for convenience, but in my case it's actually in a mongo database.) dogs: - breed: "wolf" name: "Fido" - breed: "wolf" name: "Roger" - breed: "dingo" name: "Nipper" - breed: "dingo" name: "Ernie" - breed: "corgi" name: "Bernadi" - breed: "corgi" name: "Queenie" - breed: "poodle" name: "Christopher" - breed: "poodle" name: "Tony" etc So now I want to create a list of the available breeds. Dog.find().exec(err, dogs) { breeds = []; dogs.each(function(dog)) { if (breeds.indexOf(dog.breed) ==

how compare a datetime in sails.js Model? here it is what i did but without luck. var _date = moment().format('YYYY-MM-DDTHH:mm:ss.SSS') + 'Z'; Game.find({ where:{ active: true, start: { '>=' : _date } }, limit: 1, sort: 'start asc' }, function(err, game) { console.log('ERROR: ' + err); console.log('Game OBJ' + game.toString()); }); The datetime type is transformed into an actual Javascript date in Waterline (the Sails ORM). So it needs to be compared against a date object, not a string. You can keep your code exactly as it is, but change the first line to: var _date = new Date(moment().format

I'm new to Sails.js (v0.10.5) and Waterline ORM. I have 3 tables in database: users (id, name), roles(id, alias) and join table users_roles(user_id, role_id). It's important not to change table names and field names in database. I want Policy entity to be a join entity between User and Role. Here is some mapping code: //User.js module.exports = { tableName: 'users', autoCreatedAt: false, autoUpdatedAt: false, attributes: { id: { type: 'integer', required: true }, name: { type: 'string' }, roles: { collection: 'role', via: 'users', through: 'policy' }, } } //Role.js module.exports = { tableName

I'd like to add a default toDisplay function to all models which will use metadata, not unlike attribute/association definitions, to perform manipulations on the instance's attributes/associations making them suitable for display in the UI. for example: Foo.findOne(someId) .exec(function(err, foo) { ... res.view({ foo: foo.toDisplay(), }); }); So, I'd like to add this function too all models. I can imagine a Model.prototype.toDisplay = ... solution, but I'm not sure where to get Model from (some long require('waterline/..../model') path?), and if I had Model, where to put that snip-it. Please
