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" SQLSTATE [23000]:完整性约束违规:1062重复输入''关键' PRIMARY' (SQL:插入device
(vehicleID
)值(avs))"。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

}
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
答案 0 :(得分:0)
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);
}
