Wenn ich versuche, Daten in die Tabelle einzufügen, erhalten Fehler

Question

Ich erstellte Seite mit Laravel zum Abrufen von Daten aus der Datenbank in die Tabelle. Auf der gleichen Seite habe ich die Möglichkeit, Daten in die Datenbank einzufügen. Beim Einfügen von Daten in die Datenbank wird der Fehler "SQLSTATE [23000]: Verletzung Integritätseinschränkung: 1062 Doppelter Eintrag '' für den Schlüssel 'PRIMARY' (SQL: Einfügen in device (vehicleID) Werte (avs))" angezeigt. Zuvor funktionierte es einwandfrei und ich konnte die Daten einfügen. Meine Ansicht Seite wird unter

@extends('app') 

@section('content')

Controller Seite gibt, ist

<?php 

namespace App\Http\Controllers; 

use Mail; 
use Illuminate\Support\Facades\DB; 
use App\Device; 
use App\Http\Requests\createUserRequest; 
use Illuminate\Support\Facades\Auth; 
use Illuminate\Support\Facades\Validator; 
use Illuminate\Support\Facades\Input; 
use Illuminate\Pagination\Paginator; 

class VehicleController extends Controller 
{ 
    public $type = 'Device'; 





    public function getIndex() 
    { 


     $devices = DB::table('device')->simplePaginate(15); 
     return view('vehicle.vehicleAdmin')->with('devices', $devices); 
    } 


    public function vehicleInsert() 
    { 
     $postUser = Input::all(); 
     //insert data into mysql table 
     $data =  array('vehicleID'=> $postUser['vehicleID'] 
     ); 
     // echo print_r($data); 
     $ck = 0; 
     $ck = DB::table('device')->Insert($data); 
     //echo "Record Added Successfully!"; 
     $devices = DB::table('device')->simplePaginate(50); 
     return view('vehicle.vehicleAdmin')->with('devices', $devices); 


    } 


    public function delete($id) 
    { 
     DB::table('device')->where('vehicleID', '=', $id)->delete(); 
     return redirect('vehicleAdmin'); 
    } 

} 

und die Route Seite ist

Route::any('vehicleAdmin', 'VehicleController@getIndex'); 
Route::post('vehicleAdmin', 'VehicleController@vehicleInsert'); 
Route::delete('vehicle/delete/{id}', 'VehicleController@delete'); 

Kann jemand mir sagen, warum dieser Fehler kommt, und was ich tun müssen? Vielen Dank im Voraus

Answer 1

ich denke VehicleID Autoinkrement ist und keine Notwendigkeit

public function vehicleInsert() 
{ 
    $postUser = Input::all(); 
    //insert data into mysql table 
    $data =  array('other-columns'=> $postUser['other-columns'] 
    ); 
    // echo print_r($data); 
    $ck = 0; 
    $ck = DB::table('device')->Insert($data); 
    //echo "Record Added Successfully!"; 
    $devices = DB::table('device')->simplePaginate(50); 
    return view('vehicle.vehicleAdmin')->with('devices', $devices); 


}
