node.js - NodeJS Sequelize 制作主表降序示例

Question

我卡住了如何在 NodeJS 中制作降序主表。我是这样发展的

models.Users.findAll({
    where: {id: usersArray},
    include: [
        {model: models.Users_Answers}
    ],
    order: [
        [models.Users_Answers, 'id', 'ASC']
    ]
}).then(function(answers) {
    /* Do something */ 
});

但是我改成下面的时候遇到error energy encountered.

models.Users.findAll({
    where: {id: usersArray},
    include: [
        {model: models.Users_Answers}
    ],
    order: [
        [models.Users, 'id', 'DESC']
        [models.Users_Answers, 'id', 'ASC']
    ]
}).then(function(answers) {
    /* Do something */ 
});

Unhandled rejection Error: 'Users' in order / group clause is not valid association

Answer 1

你需要这样做，

models.Users.findAll({
    where: {id: usersArray},
    include: [
        {model: models.Users_Answers}
    ],
    order: [
        [db.Sequelize.col('id'), 'DESC'],
        [models.Users_Answers, 'id', 'ASC']
    ]
}).then(function(answers) {
    /* Do something */ 
});
