Question

我正在尝试将我的用户模型与我的组织模型相关联，但我遇到了一个错误，即csv.DictReader，尽管事实上我正在遵循将用户与我的组织关联的过程。我正在使用的关联方法类型是否可能导致问题？

用户模型（user.js）：

Error: user is not associated to organization!

组织模式（organization.js）：

var bcrypt   = require('bcrypt-nodejs');

module.exports = function(sequelize, DataTypes) {

var User = sequelize.define('user', {
    user_id: {
        type: DataTypes.INTEGER,
        autoIncrement: true,
        primaryKey: true
    },
    firstName: {
        type: DataTypes.STRING,
        field: 'first_name'
    },
    lastName: {
        type: DataTypes.STRING,
        field: 'last_name'
    },
    email: {
        type: DataTypes.STRING,
        isEmail: true,
        unique: true
    },
    password: DataTypes.STRING,
    organizationId: {
        type: DataTypes.INTEGER,
        field: 'organization_id',
        allowNull: true
    }
}, {
    freezeTableName: true,
    classMethods: {
        generateHash: function(password) {
            return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null);
        },
        associate: function(db) {
            User.belongsTo(db.Organization, {foreignKey: 'organizationId'});
        },
    },
    instanceMethods: {
        validPassword: function(password) {
            return bcrypt.compareSync(password, this.password);
        },
    },


});
    return User;
}

要连接的表的索引（db-index.js）：

module.exports = function(sequelize, DataTypes) {

var Organization = sequelize.define('organization', {
    organizationId: {
        type: DataTypes.INTEGER,
        field: 'organization_id',
        autoIncrement: true,
        primaryKey: true
    },
    organizationName: {
        type: DataTypes.STRING,
        field: 'organization_name'
    },
    admin: DataTypes.STRING,
    members: DataTypes.STRING
},{
    freezeTableName: true
});

    return Organization;
}

是否会触发此错误：

var Sequelize = require('sequelize');
var path = require('path');
var config = require(path.resolve(__dirname, '..', '..','./config/config.js'));
var sequelize = new Sequelize(config.database, config.username, config.password, {
    host:'localhost',
    port:'3306',
    dialect: 'mysql'
});

sequelize.authenticate().then(function(err) {
    if (!!err) {
        console.log('Unable to connect to the database:', err)
    } else {
        console.log('Connection has been established successfully.')
    }
});

var db = {}

db.Organization = sequelize.import(__dirname + "/organization");

db.User = sequelize.import(__dirname + "/user");

db.Records = sequelize.import(__dirname + "/records");

db.User.associate(db);
db.Records.associate(db);

db.sequelize = sequelize;
db.Sequelize = Sequelize;

sequelize.sync();

module.exports = db;

您需要设置关联的反向，组织有多个用户
