Call to undefined method App\Student::contains() in laravel - mysql

Question

In my blade view, it is giving me an error Call to undefined method App\Student:: contains()
my controller
if($auth->user()->getRoleNames() == '["Parent"]'){
$id = $auth->user()->Parents_id;
$parent = ParentName::find($id);
$student = $parent->students;
$announce = AnnounceMent::get();
$roletype='parent';
return view('announcement.index',compact('student','roletype','announce'));
}
my view file
#foreach($announce as $ann)
#if($student->contains('id', $ann->student_id))
<tr>
<td>{{$i}}</td>
<td>{{$ann->announcement_type}}</td>
<td>
<?php $course = \App\Course::find($ann->course_id) ?>
{{$course->course_name}}
</td>
<td>
<?php $student = \App\Student::find($ann->student_id) ?>
{{$student['firstname'].' '.$student['lastname']}}
</td>
<td>{{$ann->description}}</td>
<td>
<a class="btn btn-success" href='{{ url("viewannounce/{$ann->id}") }}'>View</a>
</td>
</tr>
#endif
#php($i++)
#endforeach
this is my collection I am getting dd($students)
Collection {#595 ▼
#items: array:3 [▼
0 => Student {#596 }
1 => Student {#597 }
2 => Student {#598 }
]
}

Answer 1

contains is a collection method, you are calling it with a non-collection, if it will be App\Student::all()->contains('something') it will work fine, but App\Student::find(1)->contains('something') or App\Student::contains('something') will not work
Tinker results
>>> App\User::find(1)->contains('email')
BadMethodCallException with message 'Call to undefined method App/User::contains()'
>>> App\User::all()->contains('email')
=> false
>>> App\User::contains('email')
BadMethodCallException with message 'Call to undefined method App/User::contains()'
>>>
You can do
$student->id == $ann->student_id
in your situation, I guess.
