当我试图插入数据到表中，得到错误

Question

我创建页面使用laravel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。当向数据库插入数据时，其显示错误“SQLSTATE [23000]：完整性约束违规：1062'PRIMARY'键的重复条目'（SQL：插入到device（vehicleID）值（avs））”。以前它工作正常，我能够插入数据。 我的视图页得到下述

} 

和路线页面

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

任何一个可以告诉我，为什么这个错误就要来了，我需要做？ 由于提前

Answer 1

我觉得vehicleID是自动递增，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); 


}
