PHP Question

Insert data to database - LARAVEL

This creates a new project for me. However, what i want to do is to add the additional fields in the database which belong to another database table called projects_air AND to add those air details on for that project .

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;
}


ADDITIONAL DATA TO INSERT TO DATABASE:

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


I want that these data also belong to a project they both(projects table and projects_air table) have a column called "project_id"

I HAVE TRIED USING THIS
$air = $project->air()->create($airattributes);
BUT IM GETTING AN ERROR THAT COLUMN PROJECTS_ID DOES NOT EXIST WHICH IS TRUE. IT SHOULD BE PROJECT_ID BUT I DONT KNOW WHERE THE ERROR IS

here you can view the interface: http://188.166.166.143/projects/add

UPDATE:
Air Model:

<?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',
];
}

Answer

define the relations in your model

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

then in your controller

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