         {{ $school->start_date }} //from admission table  date 11/22/2018
         @enforeach

Answer 1

SchoolDetails 关系应该与学校而不是添加，因此从入学模型中删除 SchoolDetails() 并将其添加到学校模型

学校模型：

public function Admission()
{
    return $this->hasMany('App\Admission');    
}
public function SchoolDetails()
{
    return $this->hasOne('App\SchoolDetails');    \\Edited
}

准入模式：

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

SchoolDetails 模型：

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

然后您可以相应地更改您的视图：

@foreach($schools as $i => $school)
    {{ $school->School->name}} from user table Ravi
    {{ $school->School->SchoolDetails->contact_person}}  // This Line is changed
    {{ $school->start_date }}
@enforeach
