Laravel 9: Difficulty with Eager Loading Nested Relationships in a Polymorphic Setup
I tried several approaches but none seem to work. I've searched everywhere and can't find a clear answer. I need some guidance on I'm collaborating on a project where I've looked through the documentation and I'm still confused about I'm running into an scenario with eager loading nested polymorphic relationships in Laravel 9. I have a `Comment` model that can belong to either a `Post` or a `Video`. The setup looks something like this: ```php class Comment extends Model { public function commentable() { return $this->morphTo(); } } class Post extends Model { public function comments() { return $this->morphMany(Comment::class, 'commentable'); } } class Video extends Model { public function comments() { return $this->morphMany(Comment::class, 'commentable'); } } ``` In my controller, Iām trying to fetch posts along with their comments and the comments' authors in one go, using eager loading: ```php $posts = Post::with(['comments', 'comments.author'])->get(); ``` However, when I access the loaded relationships in my view, I get the following behavior: `InvalidArgumentException: Relationship [author] does not exist on this model.` It seems like Laravel is unable to find the `author` relationship on the `Comment` model. I defined the `author` relationship like this: ```php class Comment extends Model { public function author() { return $this->belongsTo(User::class); } } ``` I've double-checked my database structure, and the `comments` table has a `user_id` column that should link to the `users` table. I've also verified that there are indeed comments with associated users in my database. Additionally, I tried to simplify the eager loading to just: ```php $posts = Post::with('comments.author')->get(); ``` But the behavior continues. I even checked if the `author` relationship works when accessed individually: ```php $comment = Comment::find(1); $author = $comment->author; ``` This works fine, so Iām confused why it fails when attempting to eager load it. Is there something I might be missing in the way Iām referencing the nested relationships, or is it a limitation with polymorphic relationships in Laravel? Any insights would be greatly appreciated! Any ideas what could be causing this? For context: I'm using Php on CentOS. Any advice would be much appreciated. Any ideas how to fix this? I'm working with Php in a Docker container on Ubuntu 22.04. Hoping someone can shed some light on this. I'm working with Php in a Docker container on Windows 11. What am I doing wrong?
