我有两个laravel一个本地安装，另一个安装在覆盆子pi上。我正在使用git存储库进行同步。
除了一件事之外，一切都很好：我在老师和学校之间有一对多的关系。
这是我的老师模特：
教师 - 模特
<?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 $this->belongsTo('App\School');
}
}
这是Web版本中断的部分
教师 - 查看
@foreach ($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;
use App\Teacher;
use App\School;
use Illuminate\Http\Request;
use App\Http\Requests\StoreTeacher;
use App\Http\Controllers\Controller;
use Illuminate\Contracts\Validation\Validator;
class TeacherController extends Controller
{
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('auth:admin', ['except' => 'logout']);
}
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
$teachers = Teacher::all();
$schools = School::all();
return view('admin.teachers.index')
->with('teachers', $teachers)
->with('schools', $schools);
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
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!');
}
/**
* Display the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function show($id)
{
$teacher = Teacher::findOrFail($id);
return view('admin.teachers.show')->with('teacher', $teacher);
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function edit($id)
{
$teacher = Teacher::findOrFail($id);
return view('admin.teachers.edit')->with('teacher', $teacher);
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param int $id
* @return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
//
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function destroy($id)
{
$teacher = Teacher::findOrFail($id);
$teacher->delete();
return redirect('/admin/teachers')->with('status', 'Teacher deleted!');
}
}
这是错误：

最难以理解的部分是，在本地版本的应用程序中，一切正常。
谢谢你的帮助

尝试将$teacher->school->name替换为$teacher->school()->name。
