Bookshelf.js - how to save many-to-many relationship?

Question

I\'m having troubles saving data in a \"many-to-many\" relationship.

Here are my models:

 var CoursePeople = bookshelf.Model.extend({
     tableName: \'c

What you want to do here is attach the ids to your relation, like this:

app.post('/users/', function(req, 
  console.log(req.body);
  var courses_ids = req.body.courses_ids; //array of ids
  delete req.body.courses_ids;
  new User(req.body).save()
    .then(function(user){
     // this is important
      return user.courses().attach(courses_ids);
    }).catch(function(error){
       console.log(error);
    });
});

It is also stated in the official docs: http://bookshelfjs.org/#Model-attach
