我的模特:
'use strict';
module.exports = function(sequelize, DataTypes) {
var Entity;
return Entity = sequelize.define('Entity', {
name: {
type: DataTypes.STRING,
allowNull: false
}
}, {
classMethods: {
associate: function(models) {
return Entity.belongsToMany(models.User);
}
}
});
};
和
'use strict';
module.exports = function(sequelize, DataTypes) {
var User;
return User = sequelize.define('User', {
name: {
type: DataTypes.STRING,
allowNull: false
},
username: {
type: DataTypes.STRING,
allowNull: false,
unique: true
},
email: {
type: DataTypes.STRING,
allowNull: false,
unique: true,
validate: {
isEmail: true
}
},
password: {
type: DataTypes.STRING,
allowNull: false
},
status: {
type: DataTypes.ENUM('active', 'inactive'),
defaultValue: 'active'
}
}, {
instanceMethods: {
display: function() {
var user;
user = {
name: this.name,
email: this.email,
username: this.username,
active: this.active
};
return user;
}
}
}, {
classMethods: {
associate: function(models) {
return User.belongsToMany(models.Entity);
}
}
});
};
我想创建一个用户,然后将一个实体附加到该用户,所以我正在做:
newUser = {
name: req.body.name,
email: req.body.email,
username: req.body.username,
password: req.body.password
};
global.db.User.create(newUser).then(function(dbUser) {
var newEntity;
newEntity = {
name: newUser.name + " Default Entity"
};
console.log(dbUser);
return dbUser.createEntity(newEntity);
}).then(function(dbEntity) {
return console.log(dbEntity);
});
但我收到错误:[TypeError: Object [object SequelizeInstance] has no method 'createEntity']
这是使用Sequelize
v2.0.0-rc8
我做错了什么?
答案 0 :(得分:2)
dbUser是一个实例,因此dbUser.createEntity()
正在调用createEntity()
实例上的实例方法dbUser
。哪个不存在。
正确的解决方案是在create
模型上调用Entity
,UserId
字段设置为dbUser.id
。所以,像:
global.db.Entity.create({name: 'blah blah blah', UserId: dbUser.id})
(你可能不得不弄乱大写)。
另外,我想你可能想要User.hasMany(models.Entity)
,但那只是让我措手不及的事。
