Sequelize: can attribute have value from relation attribute data? - node.js

Question

i don't know if this is possible, there are 2 models which are associated through relation, and models are defined this way:
sequelize.define('account_has_plan', {
account_id: {
type: DataTypes.INTEGER(10),
allowNull: false,
primaryKey: true,
references: {
model: 'account',
key: 'id'
}
},
plan_id: {
type: DataTypes.INTEGER(10),
allowNull: false,
primaryKey: true,
references: {
model: 'plan',
key: 'id'
}
},
type_id: {
type: DataTypes.INTEGER(10),
allowNull: false,
primaryKey: true,
references: {
model: 'type',
key: 'id'
}
},
create_at: {
type: DataTypes.DATE,
allowNull: true,
defaultValue: 'CURRENT_TIMESTAMP'
},
update_at: {
type: DataTypes.DATE,
allowNull: true,
defaultValue: 'CURRENT_TIMESTAMP'
}
}, {
tableName: 'account_has_plan',
underscored: true,
freezeTableName: true,
timestamps: false
});
sequelize.define('type', {
id: {
type: DataTypes.INTEGER(10),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
name: {
type: DataTypes.STRING,
allowNull: false
},
element: {
type: DataTypes.ENUM('Meal','Workout','Status'),
allowNull: false
}
}, {
tableName: 'type',
freezeTableName: true,
timestamps: false
});
the code on which calls the models and execute the query to DB is this:
var model = $.loadModel("account_has_plan");
var type = $.loadModel("type");
model.belongsTo(type);
var query = {
where: {
account_id: $.params.accountId
},
limit: $.query.limit || 12,
offset: $.query.offset || 0,
attributes:["account_id"],
include: [{
model: type
}]
};
model.findAll(query)
.then(function(data){
$.data = data;
$.json();
})
.catch(function(err){
console.log(err);
errorHandler.throwStatus(500, $);
});
this way the data from the server responds like this:
{
"account_id": 1,
"type": {
"id": 2,
"name": "Arms",
"element": "Workout"
}
}
there is actually no problem with this data, but i am forced to follow a pattern from docs i was provided with, which the difference there is that type is actually a string value rather than object value as presented in the example, so in the end the data structure i try to get has to be like this:
{
"account_id": 1,
"type": "Arms"
}
i have actually how idea on how to achieve this, i know i have little practice with sequelize, maybe this has to be defined through a model method or using through in the reference (which i have tried but returns error)
but the point is.. i need to know if it can be possible before i have to report a change on the REST documentation which is big

First of all, since what you'll be getting through a sequelize query are instances, you need to convert it to "plain" object. You could do that by using a module called sequelize-values.
Then you should be able to manually map the value to the one you're looking for.
model.findAll(query)
.then(function(data){
return data.map(function(d){
var rawValue = d.getValues();
rawValue.type = rawValue.type.name;
return rawValue;
});
})
.then(function(data){
$.data = data;
$.json();
})
.catch(function(err){
console.log(err);
errorHandler.throwStatus(500, $);
});
