Laravel 9 Eloquent Relationship Query Not Filtering as Expected with 'whereHas'
I'm working on a project and hit a roadblock. I'm stuck on something that should probably be simple. I'm integrating two systems and I've been struggling with this for a few days now and could really use some help. I'm not sure how to approach I've been banging my head against this for hours. I've searched everywhere and can't find a clear answer... I'm trying to filter a list of `Post` models that have a specific tag using Eloquent's `whereHas` method, but it's returning results that I didn't expect. I have a `Post` model that has a many-to-many relationship with a `Tag` model. Here's the relevant model code: ```php class Post extends Model { public function tags() { return $this->belongsToMany(Tag::class); } } class Tag extends Model { public function posts() { return $this->belongsToMany(Post::class); } } ``` In my controller, I am trying to retrieve posts that have the tag 'Laravel': ```php $posts = Post::whereHas('tags', function ($query) { $query->where('name', 'Laravel'); })->get(); ``` However, I am getting posts that do not have the 'Laravel' tag. I've double-checked the database, and the relationships seem fine. I also tried using `with` instead of `whereHas`, but that doesn't filter the posts, just eager loads them. I also cleared the cache and double-checked the tag names in the database, ensuring they match exactly (case-sensitive). The output of my SQL query looks like this: ```sql SELECT * FROM posts WHERE id IN ( SELECT post_id FROM post_tag WHERE tag_id IN ( SELECT id FROM tags WHERE name = 'Laravel' ) ); ``` I suspect there might be an scenario with how the relationships are set up or maybe I'm not querying correctly. Any insights or suggestions would be greatly appreciated! For context: I'm using Php on Linux. Any ideas what could be causing this? My development environment is Ubuntu. Has anyone else encountered this? Has anyone dealt with something similar? This is part of a larger web app I'm building. Any ideas what could be causing this? This is for a application running on Windows 11. Thanks for any help you can provide! I'm using Php LTS in this project. Any help would be greatly appreciated! The stack includes Php and several other technologies. Any ideas how to fix this?
