When working in this function, I search for the specific post using the postId. Then, within that post, I locate a particular comment based on the commentId. After that, I verify if the array of nested objects likes contains the userId. If not found, I add the userId to the likes array. However, despite following these steps, the userId is still not being added to the likes array. What could be causing this issue?
const likeComment = async (req, res) => {
try {
const post = await Post.findById(req.body.postId);
const comment = post.comments.find(
(comment) => comment.id === req.body.commentId
);
if (comment.likes.includes(req.body.userId)) {
var index = comment.likes.indexOf(req.body.userId);
if (index !== -1) {
comment.likes.splice(index, 1);
}
res.status(200).json("you disliked this comment");
} else {
comment.likes.push(req.body.userId);
res.status(200).json("you liked this comment");
}
} catch (err) {
console.log(err);
res.status(500).json(err);
}
};
