Modify JSON after getting a response from sequelize - mysql

Question

I get a JSON from my sequelize function. This i have to modify, because i have to send it to a database importer, who needs it in a fixed form.
Is there a way to customize this function so that I get back the desired result ?
models:
User.associate = function (models) {
User.hasMany(models.SurveyResult)
}`
SurveyResult.associate = function (models) {
SurveyResult.belongsTo(models.User)
The function:
async mediImport (req, res) {
try {
const transaction = await User.findAll({
where: { released: true },
// Select forename as Vorname, name as Nachname
attributes: [
['forename', 'PAPPS286'],
['name', 'Nachname'],
['birthdate', 'PADPS60']
],
include: [{ model: SurveyResult, attributes: ['result'] }]
}).map(user => user.toJSON())
res.send({
transaction
}
)
}
this is the JSON which i get from the function:
{
"transaction": [
{
"PAPPS286": "Tes",
"Nachname": "Josef",
"PADPS60": null,
"SurveyResults": [ {
"result": {
"name": "blau",
"email": "mail",
"birthdate": "01.02.1990"
}
}]
},
{
"PAPPS286": "Dampf",
"Nachname": "Hans",
"PADPS60": null,
"SurveyResults": [
{
"result": {
"name": "blau",
"email": "mail",
"birthdate": "01.02.1990"
}
}
]
},
]
},
This is the JSON form i need:
{
"transaction": [
PAD{
"PAPPS286": "Tes",
"Nachname": "Josef",
"PADPS60": null,
"MH": {
"name": "blau",
"email": "mail",
"birthdate": "01.02.1990"
},
PAD{
"PAPPS286": "Dampf",
"Nachname": "Hans",
"PADPS60": null,
"MH": {
"name": "blau",
"email": "mail",
"birthdate": "01.02.1990"
}
},
]
},
Perhaps there is a way to modify the JSON after i get it back. But i dont Knoe how this can be work.

The below map does what I think you are looking for. You may need to modify it, especially around accessing the variables you need, based on the key. (t.PAPPS286 and t.PADPS60)
Additionally, I am only grabbing the first survey result SurveyResults. Unsure what you want if there are none or if there are more than 1.
var obj = {
"transaction": [{
"PAPPS286": "Tes",
"Nachname": "Josef",
"PADPS60": null,
"SurveyResults": [{
"result": {
"name": "blau",
"email": "mail",
"birthdate": "01.02.1990"
}
}]
},
{
"PAPPS286": "Dampf",
"Nachname": "Hans",
"PADPS60": null,
"SurveyResults": [{
"result": {
"name": "blau",
"email": "mail",
"birthdate": "01.02.1990"
}
}]
},
]
}
obj.transaction = obj.transaction.map((t) => {
return Object.assign({
"PAPPS286": t.PAPPS286,
"Nachname": t.Nachname,
"PADPS60": t.PADPS60,
"MH": {
"name": t.SurveyResults[0].result.name,
"email": t.SurveyResults[0].result.email,
"birthdate": t.SurveyResults[0].result.birthdate
}
})
})
console.log(obj);
