Php Laravel 5.1雄辩的orm关系

我有以下设置：

Profile.php模型：

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Profile extends Model
{

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

<?php namespace App\Models;

use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

class User extends Model implements AuthenticatableContract, CanResetPasswordContract
{
    use Authenticatable, CanResetPassword;

    public function profile()
    {
        return $this->hasOne('App\Models\Profile');
    }
}

如何根据关系保存到配置文件？由于外键约束，我无法直接保存到配置文件

谢谢

您可以根据关系保存到配置文件，如下所示：

public function signup(Request $request)
{
  $user = new User;
  $profile = new Profile;
  $user->email = $request->input('email');
  $user->first_name = $request->input('first_name');
  $user->last_name = $request->input('last_name');

  $user->password = Hash::make($request->input('password'));

  $user->save();
  $role = Role::whereName('user')->first();

  $profile->city = $request->input('city'); ---> profile model
  $profile->gender = $request->input('gender'); --> profile model

  //save profile 
  $user->profile()->save($profile);

} 

public function signup(Request $request)
{
  $user = new User;
  $profile = new Profile;
  $user->email = $request->input('email');
  $user->first_name = $request->input('first_name');
  $user->last_name = $request->input('last_name');

  $user->password = Hash::make($request->input('password'));

  $user->save();
  $role = Role::whereName('user')->first();

  $profile->city = $request->input('city'); ---> profile model
  $profile->gender = $request->input('gender'); --> profile model

  //save profile 
  $user->profile()->save($profile);

}
