如何使用外键进行Eloquent搜索查询

Question

我试图通过搜索列（patient_id）在（预订）表中创建搜索框，此列是（患者）表的外键，此列（patient_id）通过foreach获取（patient_name）的数据{{$ booking-> patient-> patient_name}}，问题是我不知道如何在我的控制器（BookingController）中通过（patient_id）搜索（patient_name），任何帮助？对不起我的语言:(

这是我的预订控制器：

public function index()
{
    $search = \Request::get('search');

     $bookings = Booking::with('patient')->where('status','=', null)-
>where('patient_name','like', '%'. $search. '%' )->paginate(10);

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

我的预订模式：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Eloquent;

class Booking extends Eloquent
{

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

}
} 

我的患者模型：

<?php

namespace App;

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

}
}

更新..这是索引页面

    {!! Form::open(['method'=>'GET','url'=>'booking','class'=>'navbar-form navbar-left','role'=>'search'])  !!}
<a href="{{ url('booking.index') }}" class="btn btn-primary btn-sm"><span class="glyphicon glyphicon-plus"></span> Add</a>

Answer 1

Eager Loading

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

或者，如果您不确定将患者分配给所有预订，那么您应该使用以下查询：

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

Answer 2

public function index(Request $request)
{
    $keyword = $request->input('searchquery');
    $bookings= Booking::whereHas('patient', function($query) use ($keyword) {$query->where('patient_name', 'like', $keyword);})->get();
    return view('booking.index',compact('bookings'));
}

Answer 3

尝试：

dd($search);

如果您从某些输入中搜索，请尝试使用：

$serach = $request->serach;
