Why is Laravel not displaying a post via BelongsTo()?

Question

Laravel

Good afternoon. I can't figure out relationships in Laravel.
Unable to select a record from the posts.slug column from the posts table

public function showSinglePost(Category $category, $slug)
    {

        $this->data['post'] = $category->belongsTo('App\Post', $slug, 'slug')->get();

        dd($this->data['post']);

    }

Answer 1

Write belongsTo in the model itself, and load via $category->load('post') if your category is already selected. Or $category->with('posts')->get() if the category is not loaded, because the relay needs to get data from the category itself in order to pull related posts.
