Checkit with a bookshelf, how to catch an error and stop DB execution?

Question

I am trying to use checkit with a bookshelf, and after adding validation rules, deliberately breaking them, my # catch block promise doesn't seem to catch the error. (I might also not completely understand the use of the catch here)

var validationRules = new Checkit({
    email: 'required',
    password: 'required'
});

var User = bookshelf.Model.extend({
    tableName: 'users',

    initialize: function() {
        this.on('saving', this.validateSave);
    },
    validateSave: function() {
        validationRules.run(this.attributes);
    }
});

User.forge({}).save().then(function(validated) {
    console.log('this shouldnt trigger');
}).catch(function(err) { // this doesnt seem to be working the way I expect
    console.log(e.message);
});

When I create an empty user object, I get the following unhandled stacktrace error, and also seeing how the DB query is built (which may be a separate issue for the bookshelf project and what happens when you connect to the “save” ')

Possibly unhandled Checkit Errors - email: The email is required; password: The password is     required

ER_NO_DEFAULT_FOR_FIELD: Field 'email' doesn't have a default value

I have 2 questions:

• debug: true knex, stacktrace ER_NO_DEFAULT_FOR_FIELD, , SQL-. , Checkit , SQL ?
• #catch? , . (, e.message #catch MySQL, Checkit). , ?

Checkit promises, promises , , return checkit.run, , .

Bluebird ( promises) , , . , :

validationRules.run(this.attributes);

To:

return validationRules.run(this.attributes);

validateSave, .
