如何用猫鼬制作评论模型？

Question

I'm making a website that uses mongoose, passportjs and nodejs. I want to add a comment functionality but I don't know how to make the comment model.

I already created my photos model, user model(this model works with passportjs) and comment model. But then I didn't know what to do.

I want user to write their own comment which my users can and when adds a comment I want to show username automatically on comments section with 'req.user.username' but I want this username to be saved in database

Answer 1

You must have a separate model for comments. Reason being, Comment count may go up to thousands and even more than that, if you maintain an array, it will not be easy to maintain and will be slow as well.

Even, if you create a new model for comment, it will help you in pagination as well. Your commentSchema model may contain:

1. PostRefId
2. comment
3. commentBy
4. createdAt
5. updatedAt
6. isDeleted
7. count so on.
