在model.update上的sequelize错误

Question

  

未处理拒绝TypeError：undefined不是函数

错误我想在MySQL上面的sequelize中更新我的表。

这里是一段代码片段，可以通过令人惊讶的评论来触发错误：

topic.update(
        { name: "adfa"},
        { where: { tid: 1} }
);

//topicAttribute.update({ value: "name 2"},{where: {TOPIC: 2,name: "nadpis" }});

现在这是我的两个模特：

var topic = sequelize.define('topic', {
        tid: {  type: Sequelize.INTEGER,
                field: 'tid',
                primaryKey: true                    
        },
        name: { type: Sequelize.STRING,
                field: 'name'       
        },
        added: {    type: Sequelize.DATE,
                    field: 'added'
        },
        addedBy: {  type: Sequelize.STRING,
                    field: 'added_by'
        },
        changed: {  type: Sequelize.DATE,
                    field: 'changed'
        },
        changedBy: {    type: Sequelize.STRING,
                        field: 'changed_by'
        },
        parent: {   type:   Sequelize.INTEGER,
                    field: 'parent'
        },
        enabled: {
                    type:   Sequelize.BOOLEAN,
                    field: 'enabled'
        }
    },
{
        tableName: 'topic',
        timestamps: false
});

var topicAttribute = sequelize.define('tAttribute', {
    parent: {   type: Sequelize.INTEGER,
            field: 'TOPIC',
            primaryKey: true
    },
    name: { type: Sequelize.STRING,
            field: 'name',
            primaryKey: true
    },
    value: {    type: Sequelize.STRING,
                field: 'value'
    },
},
{
    tableName: 'topic_attribute',
    timestamps: false
});

topic.hasOne(topic, {foreignKey: 'tid'});
topic.hasMany(topicAttribute, {foreignKey: 'parent'});
topicAttribute.belongsTo(topic, {foreignKey: 'parent'});

最后我的堆栈跟踪：
