问题 I have an existing postgres database which I am using to build a sails.js driven website, utilising waterline for ORM. I'm fine with using my database in its existing form for everything other than population i.e. joining tables. When working with a non-production database I'm comfortable with how waterline can produce join tables for me, but I'm really unsure how to bypass this to work with the current tables I have and their foreign key relationships. To give an idea of the types of tables

问题 I am having an error inserting data into my join table and I don't know if I'm doing it the right way. Here are my 2 models that have the many to many association.

问题 I am using Sails v0.11 and am developing an standalone importer script in order to import data to mongoDB and - that is now the not-working part - build the associations between the models.

问题 this is my first time using sails.js with mySQL database and I'm really confused about this error. I have a controller & model called 'company'. It relates to table 'company' in mySQL database. The table itself has one-to-many associations with two tables called 'module' and 'user' (each user/module must connect with one company id). I've set the foreign key in the MySQL database. The problem is.. each time I open any page/action from this controller, there is this error: error: Sending 500 (

问题 I am new to NodeJS and SailsJS, was working with Rails or PHP before. I want to use SailsJS together with OrientDB. What would be the best approach? I found two options so far, but the amount of information isn't that great (yet). Go with Waterline and this sails adapter for orientdb Go one level deeper and use the binary adapter from nodejs Any help, tips, hints would be greatly appreciated.

问题 I try to use new version 1.0 and refactoring my project. I have one problem and i don't now how i can solve her. Some tables on my BD don't have primary keys and when i migrate to sails 1.0, i have this error In model friends : The primary key is set to id , but no such attribute was found on the model.

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
