Laravel 10 - implementing Eloquent relationship eager loading causing N+1 query solution in nested relationships
I've looked through the documentation and I'm still confused about I'm experiencing a important performance scenario due to what seems to be an N+1 query question when eager loading nested relationships in Laravel 10... I have a `Post` model that has many `Comment` models, and each `Comment` can have many `Reply` models. I want to load all comments along with their replies for a specific post, but it appears that Laravel is not optimizing the queries as expected. In my controller, I'm using the following code: ```php $post = Post::with('comments.replies')->find($postId); ``` However, when I debug the queries being executed, I see that for each comment, an additional query is being executed to retrieve its replies. For example, if a post has 5 comments and each comment has 3 replies, I end up with 1 query for the post, 1 query for the comments, and 5 additional queries for the replies, resulting in a total of 7 queries instead of the expected 3. To troubleshoot, I've verified that the relationships are correctly defined in the 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 also tried using the `load` method after fetching the post, but it didn't change the number of queries: ```php $post = Post::find($postId); $post->load('comments.replies'); ``` Despite these attempts, the repeated queries continue to be an scenario. Am I missing something in my eager loading approach or in the way I've defined my relationships? Any insights on how to resolve this N+1 question efficiently would be greatly appreciated. My development environment is Windows 11. I'm working on a web app that needs to handle this. What am I doing wrong?
