这为我创建了一个新项目。但是，我想要做的是在数据库中添加属于另一个名为projects_air的数据库表的附加字段，并为该项目添加这些详细信息。
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;
}
要插入数据库的其他数据：
$airattributes['dust'] = $data['dust'];
$airattributes['noise'] = $data['noise'];
$airattributes['temperature'] = $data['temperature'];
$airattributes['radiation'] = $data['radiation'];
我希望这些数据也属于一个项目，它们（项目表和projects_air表）都有一个名为“project_id”的列
我已经尝试使用$air = $project->air()->create($airattributes);但是我发现了错误，因为列项目不存在，这是错误的。它应该是PROJECT_ID但我不知道错误在哪里
在这里您可以查看界面：http://188.166.166.143/projects/add
更新： 空气模型：
<?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',
];
}

答案 0 :(得分：0)
定义模型中的关系：
class Projects extends Model {
public function air() {
return $this->hasMany('App\Projects_air');
}
}
然后在你的控制器中：
$project = Projects::create($attributes);
$air = $project->air()->create($airattributes);
