Quick Example

var Validator = require('bookshelf-validator'),
    ValidationError = Validator.ValidationError;

var DbContext = Bookshelf.initialize(config);

DbContext.plugin(Validator.plugin);

var Obj = DbContext.Model.extend({
    tableName: 'obj',
    validation: {
        'name': [
            { validator: 'notEmpty', message: 'name is required' },
            { validator: 'matches', args: [/^[a-z0-9 ]+$/i], message: 'name format incorrect'},
            function (value, context) {
                return DbContext.knex('obj').where('name', value).count('* AS count')
                    .then(function (results) {
                        if (results[0].count > 0)
                            context.addError('name already exists');
                    });
            }
        ],
        'quantity': [
            { validator: 'isInt', message: 'quantity must be integer' }
        ]
    }
});

Obj.forge({}).save()
    .then(function () {
        throw new Error('obj should not be saved');
    })
    .catch(ValidationError, function (e) {
        expect(e.errors).to.have.keys(['name', 'quantity']);
        expect(e.errors.name).to.have.length(2);
        expect(e.errors.name).to.deep.equal(['name is required', 'name format incorrect']);
        expect(e.errors.quantity).to.have.length(1);
        expect(e.errors.quantity[0]).to.equal('quantity must be integer');
    });


Obj.forge({ name: 'Name', quantity: 1 }).save()
    .then(function () {
        return Obj.forge({ name: 'Name', quantity: 1}).save()
            .then(function () {
                throw new Error('obj should not be saved');
            })
            .catch(ValidationError, function (e) {
                expect(e.errors).to.have.keys(['name']);
                expect(e.errors.name).to.have.length(1);
                expect(e.errors.name[0]).to.equal('name already exists');
            });
    });
