the sql can run @ cmd,but can`t use bookshelf achieve target. me,please!

queries model feature not instance one. change code query directly on defray model, like:

var defray = db.model.extend({     tablename: 'defray'  // id not needed, default pk name }); defray.query('where', 'purchaseid', '=', '2').fetch().then(function(model) {     console.dir(model); });
