Laravel return relationship data based on locale

Question

I have posts table that has related table where I store different translations based on post_id now when I want to return translation data based on user selected locale it says:

mb_strpos(): Argument #1 ($haystack) must be of type string, Closure given

Here is my function

$posts = Post::with('translations', function($q) {
  $q->where('translate_code', app()->getLocale());
})->get();
dd($posts); // returning error above

But if I do this

$posts = Post::with('translations')->get();
dd($posts);

I will get following results

Here is translations data details:

My question is:

How can I return the one translation that has current locale name only?

Answer 1

If you using callback in with then use array of relations like below. Older version of laravel was working which you mentioned but latest version need array of relations when using callback.

$posts = Post::with(['translations'=> function($q) {
            $q->where('translate_code', app()->getLocale());
        }])->get();
