Customize error with JSON response from controller in Laravel

Question

I'm using Jquery 3, and Laravel 5.8, and want to customize an error with JSON response from My controller.

I've tried to return response from controller, but it's appear default error message.

public function destroy($id)
    {
        $po = Po::findOrFail($id);
        $po->delete();

        if($po) {
            return response()->json([
                'message' => 'Product Owner Deleted',
                'data' => $po
            ]);
        } else {
            return response()->json([
                'msg' => 'Failed to delete a product owner / Po is assigned to project'
            ]);
        }
    }

Jquery

// Delete Data
    $('body').on('click', '#btn-destroy', function(event) {
        event.preventDefault();

        let me = $(this),
            url = me.attr('href'),
            csrf_token = $('meta[name=csrf-token]').attr('content');

        Swal.fire({
            title: 'Are you sure want to delete?',
            text: "Choose Option Wisely",
            type: 'warning',
            showCancelButton: true,
            confirmButtonColor: '#3085d6',
            cancelButtonColor: '#d33',
            confirmButtonText: 'Yes, Delete it!'
          }).then((result) => {
            if (result.value) {
                $.ajax({
                    url: url,
                    method: 'POST',
                    data : {
                        '_token': csrf_token,
                        '_method': 'DELETE'
                    },
                    beforeSend: function () {
                        toastr.warning('Deleting Data...', 'WARNING');
                    },
                    success: function(data) {   
                        toastr.success(data.message, 'SUCCESS');
                        $('#datatable').DataTable().ajax.reload();
                    },
                    error: function(xhr) {
                        let error = xhr.responseJSON; 
                        toastr.error(error.msg, 'ERROR');
                    }
                });
            }
        });
    });

I want to return error like in condition, if true show this, if false show that. But, it always return error like :

" SQLSTATE[23000]: Integrity constraint violation: 1…(id)) (SQL: delete fromposwhereid` = 1 "

how does ur table and model looks like? i would be more specific on selecting record using where $po = Po::where('id', $id)->first(); — Skeldar

@Skeldar Model (pasted.co/7f15e4a1] Migration pasted.co/a654641c but.. it's still same when I use first(). — Huda Prasetyo

@HudaPrasetyo does your table is related to other table with Primary/Foreign key? — Prashant Deshmukh.....

change your condition like that.

   $po = Po::findOrFail($id);

    if($po->delete()) {
        ...
    } else {
       ...
    }

Hmm.. still same results. It return default error message

Gabrielle-M Over a year ago

please try this Query Builder like DB::table('pos')->where('id', $id)->delete();

Gabrielle-M Over a year ago

truncate the table and do the delete using implicit model binding and check the status inside ajax request success function..

public function addCourse(Request $request)
 {
   $courseData = new Course();
   $courseSaved = $courseData->save();
   if ($courseSaved) {
     return response()->json(
       [
        'status' => 1,
        'message' => 'Course added successfully.'
       ]
     );
    } else {
       return response()->json(
          [
           'status' => 0,
           'message' => 'Something Was Wrong.'
          ]
        );
