API for updating user role using a id - Node - node.js

Question

I am trying to create a node API and test it using Postman but I keep running into errors. I can't seem to get to update the userRole of my user table. I have tried console.log(req.body.userRole) to print the incoming field I want to update the user role but it is coming up as undefined or throwing an error relating to my Cors settings / unhandledPromiseRejection error when I remove the try catch loop.
In the code below I get a message that it is updated but nothing happens to the value of the table. The userRole is the 7th column of my table and it is spelt correctly. There is a foreign key attached to the userRole table that i'm not sure is causing the error.
It is likely an error in the code as i haven't many update functions working correctly yet.
exports.updateUser = async (req, res) => {
try{
const userID = req.params.userId;
//const role = req.body.userRole;
const user = await User.findByPk(userID);
//console.log("userRole", req.body.userRole)
if(!user){
// return a response to client
res.status(404).json({
message: "Not Found for updating a user with id = " + user,
user: "",
error: "404"
});
} else {
console.log("userRole", req.body.userRole)
// update new change to database
let updatedUser = {
userID: userID,
//userRole: role
}
let userRes = user.update(updatedUser, {
returning: true,
where: {userID: userID}
});
// return the response to client
if(!userRes) {
res.status(500).json({
message: "Error -> Can not update a user with username = " + req.params.userId,
error: "Can't Update",
});
}
res.status(200).json({
message: "Updated role successfully user = " + req.params.userId,
user: updatedUser,
});
}
} catch(error){
res.status(500).json({
message: "Error -> Can not update a customer with userName = " + req.params.userId,
error: error.message
});
}
}

role model
module.exports = (sequelize, Sequelize) => {
const userRole = sequelize.define("userRoles", {
userRoleID: {
type: Sequelize.INTEGER,

return userRole;
};

Answer 1

example:
model: User
fields:
Id ( PrimaryKey )
RoleId ( Foreign Key )
model: Role
fields:
Id ( PrimaryKey )
Association in User model is like This (if a user just have a role):
User.belongsTo(models.Role);
If you change default scheme then you have to determine it:
model: User
fields:
Id ( PrimaryKey )
i_am_reference_iD ( Foreign Key to Role ID)
User.belongsTo(models.Role, {foreignKey: 'i_am_reference_iD'});
Sequelize has a complete documentation. You need to study it to avoid mistakes which they wasting too much time on dev time.
Also you need to clean your codes too.
