我在belongsToMany关系的连接表中遇到其他属性的问题。 在set或add方法中,该属性不会传递给mysql。
我跟随文件传递"通过" set方法中的属性,但它不起作用。 有人知道什么可能是错的,因为以下文档不起作用?
注意:连接的注册和更新是正确的,只有未传递给表的附加属性。
功能模型:
export default function(sequelize, DataTypes) {
const Functionality = sequelize.define('functionality', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
name: {
field: 'name',
type: DataTypes.STRING(300),
allowNull: false
}
}, {
classMethods: {
associate: function(models) {
Functionality.belongsToMany(models.privilege, { as: 'privilegies', through: models.functionality_privilege, foreignKey: 'functionality_id' });
}
},
tableName: 'functionality',
freezeTableName: true,
timestamps: true,
createdAt: 'createdAt',
updatedAt: 'updatedAt'
});
return Functionality;
}
特权模式:
export default function(sequelize, DataTypes) {
const Privilege = sequelize.define('privilege', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
name: {
field: 'name',
type: DataTypes.STRING(300),
allowNull: false
}
}, {
classMethods: {
associate: function(models) {
Privilege.belongsToMany(models.functionality, { as: 'functionalities', through: models.functionality_privilege, foreignKey: 'privilege_id' });
}
},
tableName: 'privilege',
freezeTableName: true,
timestamps: true,
createdAt: 'createdAt',
updatedAt: 'updatedAt'
});
return Privilege;
}
功能特权模型:
export default function(sequelize, DataTypes) {
const Functionalityprivilege = sequelize.define('functionality_privilege', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
edit: {
field: 'edit',
type: DataTypes.BOOLEAN
}
}, {
tableName: 'functionality_privilege',
freezeTableName: true,
timestamps: true,
createdAt: 'created_at',
updatedAt: 'updated_at'
});
return Functionalityprivilege;
}
方法创建:
create(options) {
let obj = options.payload;
return this.functionalityDao.create(obj)
.then((result) => {
return result.setPrivilegies(obj.privilegies, { through: { edit: obj.permissions }})
});
}
OR
return result.setPrivilegies(obj.privilegies, { through: { edit: true }})
答案 0 :(得分:1)
我没有设法通过'set'函数来做到这一点,但是它通过'add'方法为我工作:
result.addPrivilege(privilege, { through: { edit: true }});
它应该适用于已经存在的特权。它不适用于实体数组(在您的情况下为特权),因此我不得不多次调用“ add”方法。像这样:
return Promise.all(
privileges.map(privilege => result.addPrivilege(privilege, { through: { edit: true }}));
)
