我正在编写一个网络应用程序。后端是一个基于 Laravel 4 的 RESTFul 应用程序。
我在使用特定控制器时遇到问题。
BedsController.php
class BedsController extends \BaseController {
/**
* Display a listing of the resource.
* GET /beds
*
* @return Response
*/
public function index()
{
//
$user = JWTAuth::parseToken()->authenticate();
$data = Input::get('room');
$retorno = array();
$hoy = date('Y-m-d');
if( $data ){
$d = intval( $data );
$beds = Bed::where('room', '=', $d )->get( array('size', 'room', 'id', 'name') );
foreach( $beds as $b ){
$b->stay = Stay::where('bed', '=', $b->id )
->where('indate', '<=', $hoy )
->where('outdate', '>=', $hoy )
->get( array( 'id', 'room', 'bed', 'guest', 'booking', 'indate', 'outdate' ) );
dd( $b->stay );
if( isset( $b->stay->guest ) ){
$b->stay->huesped = Guest::find( $b->stay->guest );
}else{}
if( isset( $b->stay->booking ) ){
$b->stay->huesped = Booking::find( $b->stay->booking );
}
//dd( $b->stay );
array_push( $retorno, $b );
}
//$room = Room::find( $d );
//return $room->camas()->get( 'size', 'room', 'id');
//$beds = Bed::where('room', $data )->get();
}else{
$beds = Bed::where('hotel', '=', $user->hostel )->get( array('size', 'room', 'id', 'name') );
foreach( $beds as $b ){
$be = $b['attributes'];
$st = array();
$stay = Stay::where('bed', '=', $b->id )
->where('indate', '<=', $hoy )
->where('outdate', '>=', $hoy )
->get( array( 'id', 'room', 'bed', 'guest', 'booking', 'indate', 'outdate' ) );
//return $stay[0];
$st = $stay[0];
//dd( $stay[0] );
if( isset( $stay[0] ) ){
if( $stay[0]['attributes']['guest'] > 0 ){
$be['huesped'] = Guest::find( $b->stay->guest );
}else{}
if( $stay[0]['attributes']['booking'] ){
$be['reserva'] = Booking::find( $b->stay->booking );
}
$be['stay'] = $st;
}
array_push( $retorno, $be);
$be = array();
}
}
return $retorno;
}
因此,当我调用 mysiteapp.local/beds 时,我应该返回一个包含床数据的复合数组,如果有预订,或者该床目前已被占用,则应返回住宿信息和客人信息。
但我得到的只是一条编译错误消息:
error:{type: "ErrorException", message: "Undefined offset: 0",…}
file:"/home/pablo/htdocs/pbertran/angularh/api/vendor/laravel/framework/src/Illuminate/Support/Collection.php"
line:788
message:"Undefined offset: 0"
type:"ErrorException"
一直在谷歌上搜索,但找不到任何解决方案。
有任何想法吗?
提前致谢!
