Trying to get property of non-object (View: C:\OpenServer\domains\laravel\resources\views\admin\post\index.blade.php)

Answer 1

because you are naming your foreign key as category_id like the convention,i think you should define eloquent relationship like this
public function category() {
return $this->hasOne('App\Models\Category');
}
you should see hasOne method on Model.php file how to define one to one relationship.

Answer 2

Please check what fields your category table has!
Does it contains 'h1' field, you are accessing 'h1' key, but may be its not there at table
