I am trying to set up a patch request to the endpoint "/api/user?username=idHere". It is intended to take a json body, and be capable of reading every key value pair and updating the user in MongoDB with those new values. Right now though, the line "{$set: {key: req.body[key]}}" is interpreted literally, and it's trying to set the actual word "key" to a value instead of the key in the request body. How can I go about accomplishing this goal correctly? My current code for attempting this is below.
const updateUser = (req, res) => {
const db = mongoConnection.getDb();
const keys = Object.keys(req.body);
for (key in keys) {
db.collection('users').updateOne(
{username: req.query.username},
{$set: {key: req.body[key]}}
)
}
}
JavaScript allows you to use parameterized key names with square braces.
// Will use the value of the "key" variable for the key
{ [key]: req.body[key] }
// Will use the word "key" for the key
{ key: req.body[key] }
For example,
const req = { body: {
name: "CobaltGecko",
email: "cobalt@gmail.com"
}};
const keys = Object.keys(req.body);
for(let key in keys) {
console.log({key: req.body[key]}); // logs {key: CobaltGecko}, {key: cobalt@gmail.com}
}
for(let key in keys) {
console.log({[key]: req.body[key]}); // logs {name: CobaltGecko}, {email: cobalt@gmail.com}
}
