The Laravel Comments package by Ryan Chandler is a dead-simple package for adding comments to models in Laravel. Using the HasComments trait on your models, you can quickly add comments attributed to users:

1use RyanChandlerCommentsConcernsHasComments;
2 
3class Post extends Model
4{
5    use HasComments;
6}

Given a post model, you can add a comment using the following method:

1$post = Post::first();
2 
3$post->comment('Hello, world!');

The above example is automatically attributed to the logged-in user. You can also assign a comment to a specific user:

1$post->comment('Hello, world!', user: $user);

This package also supports comment parent threads, meaning a comment can belong to another comment.
