Question

我使用laravel创建了一个页面，用于从数据库中获取数据到表中。在同一页面中，我可以选择将数据插入数据库。当我向数据库插入数据时，它显示错误＆＃34; SQLSTATE [23000]：完整性约束违规：1062重复输入＆＃39;＆＃39;关键＆＃39; PRIMARY＆＃39; （SQL：插入device（vehicleID）值（avs））＆＃34;。以前它工作正常，我能够插入数据。我的观看页面在下面给出了

控制器页面是

 <?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');
    }

}

，路线页面是

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

任何人都可以告诉我为什么会出现这个错误，我需要做什么？在此先感谢

我认为vehicleID是自动递增的，无需插入

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);


}

当我尝试将数据插入表格时，收到错误
