Hello their I am trying to populate postedBy field on creating a new comment. When i create a comment i save it on mongodb and also I save comment._id on my feature model (as objectId) then i am sending res.json(comment) Can i populate before sending json response? I also tried but nothing happened My code-
exports.createComment = async (req, res) => {
console.log("run?");
const { featureId } = req.params;
const { content } = req.body;
const postedBy = req.auth._id;
if (!content) {
return res
.status(400)
.send({ error: "Please provide a content with your comment." });
}
const comment = new Comment({
content,
postedBy,
});
await comment.save();
await comment.populate("postedBy", "_id username");
Feature.findByIdAndUpdate(
featureId,
{ $push: { comments: comment._id } },
{ new: true }
).exec((err, result) => {
if (err) {
return res.json({
error: errorHandler(err),
});
}
});
return res.json(comment);
};```
exports.createComment = async (req, res) => {
console.log("run?");
const { featureId } = req.params;
const { content } = req.body;
const postedBy = req.auth._id;
if (!content) {
return res
.status(400)
.send({ error: "Please provide a content with your comment." });
}
const comment = new Comment({
content,
postedBy,
});
await comment.save();
// One of the ways that I use.
let populatedData= await Comment.findById(comment._id).populate("postedBy", "_id username");
console.log(populatedData)
Feature.findByIdAndUpdate(
featureId,
{ $push: { comments: comment._id } },
{ new: true }
).exec((err, result) => {
if (err) {
return res.json({
error: errorHandler(err),
});
}
});
return res.json(comment);
};
