Question

我有两张桌子，“耐心”和“预订”表。他们之间存在“一对多”的关系。我想在index_booking页面中设置一个搜索表单，用户可以在其中键入patient_name，并根据WHERE条件自动完成从患者表中显示所有patient_name。

这是预订模式

class Booking extends Eloquent
{

    public function patient()
    {
      return $this->belongsTo('App\Patient'); 
    }

    public function user()
    {
      return $this->belongsTo('App\User'); 

    }
}

这是患者模型

class Patient extends Eloquent
{
    public function booking()
    {
      return $this->hasMany('App\Booking'); 
    }

    public function user()
    {
      return $this->belongsTo('App\User'); 

    }
}

我在预订的索引页面中使用了这段代码

{!! Form::text('search_text', null, array('placeholder' => 'Search Text','class' => 'form-control','id'=>'search_text')) !!}

我不知道自动完成的代码语法。此代码工作正常，但在预订表中搜索，而不是在患者表中搜索</ p>

  public function autoComplete(Request $request) {
            $query = $request->get('term','');

            $bookings=Booking::with(['patient' => function ($query) {
            $query->where('company_id','=' ,Auth::user()->company_id);

           }])->$data=array();
            foreach ($bookings as $booking) {
                    $data[]=array('value'=>$booking->patient->patient_name,'id'=>$booking->patient->id);
            }
            if(count($data))
                 return $data;
            else
                return ['value'=>'No Result Found','id'=>''];
        }

一般情况下，在尝试使用其他代码进行自动完成后，这是我的BookingController

    namespace App\Http\Controllers;

    use Illuminate\Http\Request;
    use App\Booking;
    use App\Patient;
    use App\User;
    use Session;
    use DB;
    use Auth;
    use Input;
    class BookingController extends Controller
    {
       public function __construct()
        {
            $this->middleware('auth');
        }
        /**
         * Display a listing of the resource.
         *
         * @return \Illuminate\Http\Response
         */

        public function index()
        {

           $search = \Request::get('search');

           $bookings = Booking::whereHas('patient', function ($query) use ($search) {
             $query->where('patient_name', 'like', '%' . $search . '%');
           })->where('status','=', null)->whereHas('patient', function ($query){
             $query->where('company_id','=' ,Auth::user()->company_id); 
           })->paginate(10);

           return view('booking.index')->withBookings($bookings);

我尝试使用此代码自动完成但无法正常工作。

public function autoComplete(Request $request) {
        $query = $request->get('term','');

        $bookings=Booking::whereHas('patient', function ($query){
        $query->where('company_id','=' ,Auth::user()->company_id);

        })->$data=array();
        foreach ($bookings as $booking) {
                $data[]=array('value'=>$booking->patient->patient_name,'id'=>$booking->id);
        }
        if(count($data))
             return $data;
        else
            return ['value'=>'No Result Found','id'=>''];
    }

这是路线

Route::get('autocomplete',array('as'=>'autocomplete','uses'=>'BookingController@index'));
Route::get('searchajax',array('as'=>'searchajax','uses'=>'BookingController@autoComplete'));

Javascript代码

<script >
$(document).ready(function() {
    src = "{{ route('searchajax') }}";
     $("#search_text").autocomplete({
        source: function(request, response) {
            $.ajax({
                url: src,
                dataType: "json",
                data: {
                    term : request.term
                },
                success: function(data) {
                    response(data);

                }
            });
        },
        minLength: 3,

    });
});

</script>

这样的事情应该有效：

public function autoComplete(Request $request)
{
    $patients = Patient::where('company_id', Auth::user()->company_id)
        ->where('patient_name', 'like', "%{$request->get('term')}%")
        ->get();

    if ($patients->isEmpty()) {
        return ['value' => 'No Result Found', 'id' => ''];
    }

    return $patients->map(function ($patient) {
        return [
            'id'    => $patient->id,
            'value' => $patient->patient_name,
        ];
    });
}

希望这有帮助！
