我正在尝试通过与用户表的关系来获取动物的数据
这是我的控制人
<?php
namespace App\Http\Controllers;
use App\Animal;
use App\Clinic;
use App\Role;
use App\Slaughter;
use Illuminate\Foundation\Auth\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
class ClinicController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
$farms = User::where('role_id', 3)->get();
$user = Auth::user();
$animal = Animal::all();
return view('clinic.index', compact('user', 'animal', 'farms'));
}
public function show($id)
{
$farm = User::query()->findOrFail($id);
return view('clinic.show', compact('farm'));
}
在我的情况下，获得农场用户的同时，我想通过此关系获得农场管理员注册的动物
Model
class Clinic extends Model
{
protected $guarded = [];
public function user(){
return $this->belongsTo(User::class);
}
}
通过我的修补匠，这种关系运转得很好 这是我的索引页面
@extends('layouts.app')
@section('content')
<br><br><br><br><br><br>
<div class="container">
<div class="row justify-content-center">
<div class="col-md-20">
<div class="card">
<div class="card-header">
<center>
<h1>Clinic Dashboard</h1>
</center>
</div>
<div class="card-body">
@if (session('status'))
<div class="alert alert-success" role="alert">
{{ session('status') }}
</div>
@endif
<center>
<h2>Welcome! <strong>{{ Auth::user()->name }}</strong></h2>
</center>
<hr>
<br>
<div class="container box">
<div class="table-responsive">
<table class="table table-striped table-bordered" style="background: white">
<thead>
<tr>
<th>Farm Id</th>
<th>Farm Name</th>
<th>Action</th>
</tr>
</thead>
@foreach( $farms as $farm)
<tbody>
<tr>
<td>{{ $farm->id }}</td>
<td>{{ $farm->name }}</td>
<td><a href="/clinic/{{ $farm->id }}"><button
class="btn btn-outline-primary">View Farm
Animals</button></a></td>
</tr>
</tbody>
@endforeach
</table>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
@endsection
还有我的route
Route::get('/clinic/{farm}', 'ClinicController@show');
最后是显示view的所有错误信息
@extends('layouts.app')
@section('content')
<br><br><br><br><br><br>
<div class="container">
<div class="row justify-content-center">
<div class="col-md-20">
<div class="card">
<div class="card-header">
<center>
<h1>Farm Dashboard</h1>
</center>
</div>
<div class="card-body">
@if (session('status'))
<div class="alert alert-success" role="alert">
{{ session('status') }}
</div>
@endif
<center>
<h2>Welcome! <strong>{{ Auth::user()->name }}</strong></h2>

@foreach( $farm as $farm)
<tbody>
<tr>
<td>{{ $farm->animals->id }}</td>

@if(! $farm->animals->clinic)

<td>

</td>
@elseif( $farm->animals->clinic)
<td>{{ $farm->animals->clinic->user->name }}</td>
<td>{{ $farm->animals->clinic->vaccination ?? 'N/A' }}</td>

<td>
<a

@endif

@endforeach

我希望我提供了所有可能产生错误的字段。任何帮助将不胜感激，因为这对我来说是一个非常重要的项目 我收到的错误是
试图获取非对象的属性“动物”
答案 0 :(得分：1)
您认为自己有@foreach($farm as $farm)
您需要什么：@foreach($farms as $farm)
编辑：这仅解决了部分问题，经过仔细检查，您的人际关系不堪重负，我将看看是否可以帮忙。

此设置允许您获取特定诊所所有用户的所有动物。我也在show（）方法上利用了路由/模型绑定。无论您在URL中传递什么ID，都会自动加载诊所。
// app/User.php
class User extends Autheticatable
{
public function animals()
{
return $this->hasMany('App\Animal');
}
public function clinic()
{
return $this->belongsTo('App\Clinic');
}
}
// app/Clinic.php
class Clinic extends Model
{
public function users()
{
return $this->hasMany('App\User');
}
}
// app/Animal.php
class Animal extends Model
{
public function user()
{
return $this->belongsTo('App\User');
}
}
class ClinicController extends Controller
{
public function __construct()
{
$this->middleware('auth');
}
public function show(Clinic $clinic)
{
return view('clinic.show', compact('clinic'));
}
}
// view
@foreach($clinic->users as $farm)
@foreach($farm->animals as $animal)
{{ $animal->name }} - {{ $animal->weight }} etc...
@endforeach
@endforeach
答案 2 :(得分：0)
要获得我愿意去的$农场的相关动物
public function show($id)
{
$farm = User::with(['animals'])->findOrFail($id);
return view('clinic.show', compact('farm'));
}
然后用刀片服务器
@foreach($farm->animals as $animal)
{{ $animal->id }}
@endforeach
这当然是假设您在用户模型中设置了动物关系，就像
public function animals()
{
return $this->hasMany('App\Animals')
}
（所有未经测试）
