I have the following a Course Model with a function of trainers and I'm trying to pass it to the view so I can see the trainers for the course.

Here is my model function

public function trainers()

 return $this->belongsToMany(User::class, 'course_user');

This is my view where I'm trying to pass the Model Course and the function trainers.

<h6 class="card-subtitle text-muted">Trainer: $course->trainers()</h6>

And this is the error I'm getting:

htmlspecialchars() expects parameter 1 to be string, object given (View: /Applications/MAMP/htdocs/hs-03/resources/views/admin/courses/showCourse.blade.php)

Here is my controller:

 public function show($id)
 
 $created_bies = AppUser::get()->pluck('name', 'id')->prepend(trans('global.app_please_select'), '');
 $trainers = AppUser::get()->pluck('name', 'id');
 $tests = AppTest::where('course_id', $id)->get();$lessons = AppLesson::where('course_id', $id)->get();
 // $date = Carbon::now();
 $date = Carbon::now()->addDays(30)->toFormattedDateString();
 $user = User::find(1);
 $user->name;

 $course = Course::findOrFail($id);

 return view('admin.courses.showCourse', compact('course', 'tests', 'lessons', 'date', 'user'));

This is due to the fact that the trainers methods isn't return a String. The method like It is define in your Model is Supposed to return a Illuminate/Database/Eloquent/Relations/BelongsToMany object like you can see here. The error is because your are trying to show that object directly within your template as a String which is not possible. I suppose you want to show some thing like number of trainers. Which you can get like

<h6 class="card-subtitle text-muted">Trainer: $course->trainers()->count()</h6>

This is possible because the count method return an integer and not a object like trainers.

On another hand If you want to stick to that usage, you must insert a loop within your view which will walk through the collection of trainers which is being return by the call to $course->trainers()

@foreach($course->trainers() as $trainer)
 <h6 class="card-subtitle text-muted">Trainer: $trainer->name </h6>
@endforeach
