Question

我试图通过相关作业遍历所有用户。我在模型中创建了User-＆gt; Assignment Relationship。当我dd（$学生）我收到了他们相关作业的学生阵列，但是当我在页面上看到这个时，我没有收到作业循环。我可以在代码中遗漏什么？我确定它在html中的某个地方搞砸了。

用户模型：

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

作业模式：

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

控制器：

$students = User::where('position','student')->with('assignments')->get();

HTML

@foreach($students as $student)
                              <div class="item{{{ $isFirst ? ' active' : '' }}}">
                                  <div class = "deck">
                                    <div class = "row marg">
                                        <div class="col-md-8">
                                          <div class = "stdnt">
                                            <h1>Student Info</h1>
                                            <h1>{{$student->name}}</h1>
                                            <p>Program: {{$student->pack}}</p>

不要调用assignments方法。只需将其作为财产访问：

@foreach($student->assignments as $assignment)
    //                       ^^
@endforeach

循环对象关系Laravel
