Laravel 10: How to handle nested relationships with Eloquent when eager loading?
I'm converting an old project and I've been struggling with this for a few days now and could really use some help. I'm currently working on a Laravel 10 application where I need to retrieve a list of `Post` models along with their associated `Comments`, and each `Comment` may have a `Reply`. I'm trying to eager load the nested relationships, but I'm running into performance optimization as the query seems to be executing multiple times instead of a single optimized query. Here's the code I've written so far: ```php $posts = Post::with(['comments', 'comments.replies'])->get(); ``` When I run this code, I notice in my query log that it's executing multiple queries for each post's comments and replies. For instance, I see something like this in my logs: ``` SELECT * FROM posts; SELECT * FROM comments WHERE post_id IN (...); SELECT * FROM replies WHERE comment_id IN (...); ``` This leads to a important performance hit, especially with a large dataset. I thought using eager loading would prevent this, but it seems to fall short in this case. I've also tried using `->load()` after retrieving the posts, but it resulted in the same behavior. Additionally, I've checked to ensure that the relationships are correctly defined in my models: ```php class Post extends Model { public function comments() { return $this->hasMany(Comment::class); } } class Comment extends Model { public function replies() { return $this->hasMany(Reply::class); } } ``` I've looked through the documentation and ensured I'm following the best practices for eager loading. However, I'm still working with this scenario with the number of queries increasing exponentially as the dataset grows. Is there a better way to handle this nested eager loading in Laravel without running into N+1 problems? Any suggestions or optimizations would be greatly appreciated! I'm working on a web app that needs to handle this. Am I missing something obvious? Thanks in advance!
