Sequelize 字段关联不起作用

Sequelize field association does not work

我有两个 table。如何在 Sequelize 中第一个 table 中的 link 字段和第二个 table 中的 id 字段?

第一个table:

tables.comments = sequelize.define('comments', {
    id: {
        type: Sequelize.INTEGER,
        primaryKey: true,
        autoIncrement: true
    },
    text: Sequelize.TEXT,
    article: Sequelize.INTEGER,
    author: {
        type: Sequelize.INTEGER,
        references: "users",
        referencesKey: "id",
        allowNull: false
    },
    answer: Sequelize.INTEGER,
    rating: {
        type: Sequelize.INTEGER,
        defaultValue: 0
    }
}, {
    classMethods: {
        associate: function(models) {
            tables.comments.belongsTo(tables.models.users, {foreignKey: 'author', targetKey: 'name'});
        }
    }
});

第二个table:

tables.users = sequelize.define('users', {
    id: {
        type: Sequelize.INTEGER,
        primaryKey: true,
        autoIncrement: true
    },
    mail: Sequelize.TEXT,
    name: Sequelize.TEXT,
    pass: Sequelize.TEXT,
    status: {
        type: Sequelize.INTEGER,
        defaultValue: 0
    },
    rating: {
        type: Sequelize.INTEGER,
        defaultValue: 0
    },
    ban: {
        type: Sequelize.INTEGER,
        defaultValue: 0
    },
    key: Sequelize.TEXT
}, {
    classMethods: {
        associate: function(models) {
            tables.users.hasMany(tables.models.comments, {foreignKey: 'author'});
        }
    }
});

我需要获取 tables.comments,但是 "author" 将是 tables.users 作者的名字。我提出要求:

tables.comments.findAll({inclide: [{model: tables.users}]}).then(function(comments) {
    console.log(comments);
});

但是在字段 author 中的结果只有数字,而不是来自 users 的名字! 哪里错了?

(抱歉英语不好)

在关联类方法中,您需要使用定义类方法的 table 的列名。我假设连接条件是 comments.author = users.id

对于您的评论 table,它将是:

tables.comments.belongsTo(tables.models.users, {
  foreignKey: 'author'
});

对于您的用户 table,它将是:

tables.users.hasMany(tables.models.comments, {
  foreignKey: 'id'
});
