將數據插入數據庫 - LARAVEL

Question

這爲我創建了一個新項目。但是，我想要做的是在數據庫中添加屬於另一個名爲projects_air的數據庫表的附加字段，並在該項目上添加這些空氣詳細信息。

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; 
    } 

額外的數據接入到數據庫：

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

我想，這些數據也屬於一個項目，他們都（項目表和projects_air表）都稱爲「PROJECT_ID」

列

我曾嘗試使用此$air = $project->air()->create($airattributes);但IM發現錯誤，列項目_ID不存在，這是真實的。它應BE PROJECT_ID但我不知道哪裏出錯

在這裏你可以看到接口：http://188.166.166.143/projects/add

UPDATE： 空調型號：

<?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', 
    ]; 
}

定義您的模型中的關係：

class Projects extends Model { 
    public function air() { 
     return $this->hasMany('App\Projects_air'); 
    } 
} 

然後在你的控制器：

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