[英]Sequelize - Include based on specific attribute
I have a model defined as follows:我有一个 model 定义如下:
sequelize.define('game', {
id: {
type: type.INTEGER,
primaryKey: true,
autoIncrement: true,
},
leaderId: {
type: type.INTEGER,
allowNull: false,
references: {
model: 'users',
key: 'id',
},
},
playerId: {
type: type.INTEGER,
allowNull: false,
references: {
model: 'users',
key: 'id',
},
},
status: {
type: type.STRING,
defaultValue: 'running',
},
notes: {
type: type.TEXT,
},
});
I'm trying to use Sequelize to load all game
object and include the User
with the id equal to the playerId
field.我正在尝试使用 Sequelize 加载所有
game
object 并包含 ID 等于playerId
字段的User
。
The problem is I have two attributes ( leaderId
, playerId
) which reference the User
model so using include
as follows does not work:问题是我有两个引用
User
model 的属性( leaderId
, playerId
),因此使用include
如下不起作用:
Game.findAll({
where: conditions,
include: [{ model: User }],
})
Is there a way to specify which attribute the include
command should use?有没有办法指定
include
命令应该使用哪个属性?
const game = sequelize.define('game', {
id: {
type: type.INTEGER,
primaryKey: true,
autoIncrement: true,
},
leaderId: {
type: type.INTEGER,
allowNull: false,
references: {
model: 'users',
key: 'id',
},
},
playerId: {
type: type.INTEGER,
allowNull: false,
references: {
model: 'users',
key: 'id',
},
as:'player'
},
status: {
type: type.STRING,
defaultValue: 'running',
},
notes: {
type: type.TEXT,
},
});
game.associate = function (models) {
game.belongsTo(models.user, {
foreignKey: "playerId",
as: "player",
});
game.belongsTo(models.user, {
foreignKey: "leaderId",
as: "leader",
});
};
Game.findAll({
where: conditions,
include: ['player'],
})
Or
Game.findAll({
where: conditions,
include: [{model: User, as: 'player' }],
})
Or
Game.findAll({
where: conditions,
include: [{model: User, as: 'player', foreignKey: 'playerId' }],
})
