ブレードブレーキ表示のモデル機能を呼び出す - Laravel

Question

ラズベリーパイの2つのローカルともう1つのローカルのインストールがあります。私はgitリポジトリを使って同期しています。

私は先生と学校の間に1対1の関係があります。

これは私の先生のモデルである：

教師 - モデル

<?php 

namespace App; 

use Illuminate\Notifications\Notifiable; 
use Illuminate\Foundation\Auth\User as Authenticatable; 

class Teacher extends Authenticatable 
{ 
    use Notifiable; 

    protected $guard = 'teacher'; 

    /** 
    * The attributes that are mass assignable. 
    * 
    * @var array 
    */ 
    protected $fillable = [ 
     'name', 'email', 'password', 
    ]; 

    /** 
    * The attributes that should be hidden for arrays. 
    * 
    * @var array 
    */ 
    protected $hidden = [ 
     'password', 'remember_token', 
    ]; 

    public function students() { 
     return $this->hasMany('App\Student'); 
    } 

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

そして、これは、ウェブ版ブレイク

一部である教師 - ビュー

@foreach ($teachers as $teacher) 
       <tr> 
       <td>{{ $teacher->id }}</td> 
       <td>{{ $teacher->name }}</td> 
       <td>{{ $teacher->school->name }}</td> 
       <td>{{ $teacher->email }}</td> 
       <td><a class="btn btn-small btn-info" href="teachers/{{ $teacher->id }}">View</a></td> 
       </tr> 
@endforeach 

TeacherController

<?php 

namespace App\Http\Controllers\Admin;

    { 
     $this->middleware('auth:admin', ['except' => 'logout']); 
    } 
    /**

    * 
    * @return \Illuminate\Http\Response

    public function index() 
    { 
     $teachers = Teacher::all(); 
     $schools = School::all(); 
     return view('admin.teachers.index') 
        ->with('teachers', $teachers) 
        ->with('schools', $schools); 
    } 

    /**

    public function store(StoreTeacher $request) 
    { 
     $teacher = new Teacher; 
     $teacher->name = $request->input('name'); 
     $teacher->email = $request->input('email'); 
     $teacher->password = $request->input('password'); 
     $teacher->school_id = $request->input('school_id'); 

     $teacher->save(); 

     return redirect('admin/teachers')->with('status', 'New teacher created!'); 
    } 

    /**

    public function show($id) 
    { 
     $teacher = Teacher::findOrFail($id); 
     return view('admin.teachers.show')->with('teacher', $teacher); 
    } 

    /**

    public function edit($id) 
    { 
     $teacher = Teacher::findOrFail($id); 
     return view('admin.teachers.edit')->with('teacher', $teacher); 
    } 

    /**

    public function update(Request $request, $id) 
    { 
     // 
    } 

    /**

    */ 
    public function destroy($id) 
    { 
     $teacher = Teacher::findOrFail($id); 
     $teacher->delete(); 
     return redirect('/admin/teachers')->with('status', 'Teacher deleted!'); 
    } 
}

最も不可解な部分は、アプリのすべてのローカルバージョンで正常に動作していることです。あなたのための

おかげで

Answer 1

が$teacher->school()->nameで$teacher->school->nameを交換してみてください助けます。
