404 not found in laravel - laravel

Question

hi m trying to show a data on show.blade.php but it says 404|not found m using resource route for it. Remember m shwing the students on teacher index and from there i wants to redirect it to student/show.blade.php
StudentController:
public function show(Student $student)
{
$data = Student::findOrFail($student->id);
return view('student.show', compact('data'));
}
teacher blade file:
<td>
#foreach($row->student as $st)
<a href="{{ route('student.show', $row->id) }}">
{{ $st->student_name }}</a>
#endforeach
</td>

Answer 1

you are passing id into your controller not a model so the correction is here
public function show($student)
{
$data = Student::findOrFail($student);
return view('student.show', compact('data'));
}
and also correct this part on your blade
<a href="{{ route('student.show', $st->id) }}">
you get error not found because $student->id is returning null because you sending incorrect looping part therefore you got error 404

Answer 2

I don't know your route to students, but If you have a route like this:
Route::get('students/{id}', 'StudentController#show')->name('student.show');
What is the name of the array that you are passing with student collection from
TeacherContoller? $data?
If so, your blade file "teacher.blade.php" would be like this:
<td>
#foreach($data as $row)
<a href="{{ route('student.show', ['id' => $row->id]) }}">
{{ $row->student_name }}</a>
#endforeach
</td>
Then, you would change your method to be like this:
/**
* #var int $id
*/
public function show(int $id)
{
$data = Student::findOrFail($id);
return view('student.show', compact('data'));
}
