데이터를 데이터베이스에 삽입 - LARAVEL

Question

그러면 나를위한 새 프로젝트가 만들어집니다. 그러나 내가하고 싶은 일은 projects_air라는 다른 데이터베이스 테이블에 속한 추가 필드를 데이터베이스에 추가하고 해당 프로젝트에 대한 세부 정보를 추가하는 것입니다. 데이터베이스에 삽입 할

public function newProject(Request $request) 
    { 
     $data = $request->all(); 

     $attributes = []; 
     $attributes['title'] = $data['title']; 
     $attributes['start_date'] = date("Y-m-d h:i:s", strtotime($data['start_date'])); 
     $attributes['end_date'] = date("Y-m-d h:i:s", strtotime($data['end_date'])); 
     $attributes['created_by'] = Auth::user()->id; 
     $attributes['description'] = $data['description']; 
     $attributes['air'] = '10'; 
     $attributes['water'] = '19'; 
     $attributes['lat'] = $data['lat']; 
     $attributes['lng'] = $data['lng']; 



//  var_dump($attributes); 
//  return; 

     $project = Projects::create($attributes); 
     $air = Projects_air::create($airattributes); 

     if($project) 
      return redirect('home')->with('success', 'Project added successfully'); 

     var_dump($data); 
     return; 
    } 

추가 데이터 :

 $airattributes['dust'] = $data['dust']; 
    $airattributes['noise'] = $data['noise']; 
    $airattributes['temperature'] = $data['temperature']; 
    $airattributes['radiation'] = $data['radiation']; 

나는 이러한 데이터는 또한 그들이 모두 (프로젝트 테이블과 projects_air 테이블) 열이 "PROJECT_ID"

라는 한 프로젝트에 속해 있음을 원하는

나는이 $air = $project->air()->create($airattributes);을 사용했지만 열의 PROJECTS_ID가 존재하지 않는다는 오류 메시지를 받았습니다. IT는 PROJECT_ID해야하지만 오류가 여기

어디 인터페이스 볼 수 있습니다 잘 모릅니다 : http://188.166.166.143/projects/add

UPDATE : 에어 모델 :

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Air extends Model 
{ 
    protected $table = 'projects_air'; 
    /** 
    * The attributes that are mass assignable. 
    * 
    * @var array 
    */ 
    protected $fillable = [ 
     'project_id', 'temperature', 'radiation', 'dust', 'noise' 
    ]; 

    /** 
    * The attributes that should be hidden for arrays. 
    * 
    * @var array 
    */ 
    protected $hidden = [ 
     'id', 
    ]; 
}

을 모델의 관계를 정의하십시오.

컨트롤러에서

: 그리고 위의 코드에서 배열을 생성 그래서 어디야

$project = Projects::create($attributes); 
$air = $project->air()->create($airattributes);
