Laravel 10: Unexpected Behavior with Eager Loading and Collection Manipulation
I recently switched to Quick question that's been bugging me - I am currently working on a Laravel 10 application where I need to eagerly load related models, but I'm encountering unexpected behavior when trying to manipulate the resulting collection... I have a `Post` model that has many `Comment` models, and I want to load the comments along with the posts. However, when I try to filter the comments after eager loading, the changes do not reflect as expected. Here’s the code I’m using to fetch the posts and their associated comments: ```php $posts = Post::with('comments')->get(); ``` After this, I want to filter out comments based on a condition. For example, I want only the comments that are approved: ```php foreach ($posts as $post) { $post->comments = $post->comments->where('is_approved', true); } ``` However, when I try to access the comments later, I find that the original collection still contains all comments, including those that are not approved. I expected that the `$post->comments` would now only hold the approved comments. I've also tried using the `load` method to see if that makes a difference: ```php $posts->load(['comments' => function ($query) { $query->where('is_approved', true); }]); ``` But it still returns all comments when I access `$post->comments` outside this scope. I'm not seeing any error messages, but the behavior is not what I anticipated. Is there a proper way to filter the eager-loaded comments so that the changes are retained in the collection? Any advice on how to achieve this would be greatly appreciated! My development environment is macOS. Thanks for any help you can provide! Could this be a known issue?
