Implementing Comments for Each Post in Vue.js

When building a blogging platform or a simple comment feature in Vue.js, one common requirement is making comments specific to each post. Without a clear strategy, adding a comment section can quickly become confusing. Luckily, with a few simple steps, you can create connected comments for every post displayed using the v-for directive.

Understanding the Problem

In your current setup, you are rendering all of your posts using a loop. However, the comment section is displayed for all posts, meaning there's no clear way to associate a specific comment with its respective post. Your code already sets up a structure for the comments, so the goal here is to align the comments with their respective posts.

Solution Overview

The solution revolves around storing each post's comments within the post object itself. This way, each post will have its own array of comments, which can easily be updated and displayed. Below is a breakdown of the steps and code snippets needed to achieve this.

Step 1: Modify the Data Structure

First, we need to adjust the userList array to include an array for comments in each post. This ensures that each post can have its own unique comments.

Step 2: Update the Comment Submission Logic

The next step is to implement a function that will allow a user to submit comments. We will define a function that adds comments to the right post based on the post's unique identifier (uid):

Step 3: Update the Template to Display Comments

With the data structure and comment submission implemented, it's important to display each post's comments correctly. You will need to create a section within your post template that iterates through each post's comments.

Here’s how you can expand your HTML template:
