Retriving data from another table and inserting it into new one sequelize - mysql

Question

I've been working on a project that involves sequelize(MySQL DB).
So I have a table "InterestRate" that takes id's from two other tables(foreign keys).
bankId is stored in "Banks" table and interId is stored in another table called "Interest".
Now I want to populate this table with Postman by sending this data:
{
"bank": "BankName",
"inter": "Interest",
"nks": "4.11",
"eks": "6.24",
"time": "36"
}
BUT I want to populate table with the primary keys of these values(if existed in their own table). E.g When I send to postman I want to check table "Banks" and search "BankName" grab its id in that table, and put it in new table. Same thing for this inter thing.
Code that I have rn is trash, I know why it doesn't work but I'm really stuck.
(req, res) => {
const bank = req.body.bank;
const type = req.body.type;
const nks = req.body.nks;
const eks = req.body.eks;
const time = req.body.time;
InterestRate.create({
bankId: bank,
interId: type,
NKS: nks,
EKS: eks,
time: time,
})
.then(() => {
res.status(200).json({ message: 'Added successfully' });
})
.catch((err) => {
res.status(500).send('Error -> ' + err);
});
};
Note that all models etc. are set up correctly, it works if I enter things manually!
Thank you!

You just need to get Bank and Interest by names and use found model instances to get their ids to create InterestRate record:
async (req, res) => {
const bank = req.body.bank;
const type = req.body.type;
const nks = req.body.nks;
const eks = req.body.eks;
const time = req.body.time;
const foundBank = await Bank.findOne({
where: {
name: bank // use a real field name instead of "name"
}
})
const foundInterest = await Interest.findOne({
where: {
name: type // use a real field name instead of "name"
}
})
if(!foundBank) {
// here should be some "res.status(...).send(...)" with error message
return
}
if(!foundInterest) {
// here should be some "res.status(...).send(...)" with error message
return
}
try {
await InterestRate.create({
bankId: foundBank.id,
interId: foundInterest.id,
NKS: nks,
EKS: eks,
time: time,
})
res.status(200).json({ message: 'Added successfully' });
catch (err) {
res.status(500).send('Error -> ' + err);
}
};
