Question

我很难在视图或刀片中显示学校名称及其学生人数。我有2个表ls | grep -P '\d[eh]\.\w{1,3}'和schools 我必须显示该学校的学生人数。学校表：students，school_id，school_name，lat 学生表：student_id，fname，lname，bday，school_id

我想要显示类似这样的内容

lng

使用雄辩的[name of school1] : [count of students] [name of school2] : [count of students] [name of school3] : [count of students] [name of school4] : [count of students]关系

任何帮助都将受到高度赞赏。

Answer 1

在您的控制器中，您可以执行以下操作：

public function index() {
  $schools = School::all()

  return view ('schools.index', compact('schools'));     //ofc change the names of the views and such as you like
}

在您看来，您可以这样做：

@foreach($schools as $school)
    School: {{$school->name}} : {{$school->students()->get()->count()}} Students.
@endforeach

希望这应该有用。

修改

如果计数部分不起作用，请尝试这样

{{$school->count('students')}}

在视图中显示组名和计数
