        $schools = Admission::where('admission_classes', 'like', "%{$class}%")->where('status', '1')->orderBy('id','desc')->whereHas('school', function($query) use($city) {
    $query->where('city', 'like', $city);

         @foreach($schools as $i => $school)
         {{ $school->School->name}} from user table Ravi
       {{ $school->SchoolDetails->contact_person}} //from school_Details table  No result 
         {{ $school->start_date }} //from admission table  date 11/22/2018
         @enforeach

Answer 1

SchoolDetails关系应与学校无关，因此从入学模型中删除SchoolDetails（）并将其添加到学校模型中

学校模式：

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

入学模式：

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

学校详细信息模型：

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

然后您可以相应地更改视图：

@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

如何在laravel中从3个条件中获取所有数据？
