在 laravel 中保存相关记录 [英] Saving related records in laravel

问题描述

我有用户，而用户属于经销商.

I have users, and users belong to a dealership.

在用户注册后，我正在尝试保存一个新用户和一个新经销商.

Upon user registration, I'm trying to save a new user, and a new dealership.

用户数据库有一个 dealership_id 列，我想用新创建的经销商的 ID 填充该列.

User database has a dealership_id column, which I want to be populated with the ID of the newly created dealership.

这是我当前在 UserController 存储方法中的代码.

This is my current code in the UserController store method.

public function store()
{
    $user = new User();
    $user->email = Input::get('email');
    $user->password = Input::get('password');


    $dealership = new Dealership();
    $dealership->name = Input::get('dealership_name');

    $user->push();
    return "User Saved";

}

尝试使用 $user->push(); 用户数据已更新，但未创建或更新经销商.

Trying to use $user->push(); User data gets updated, but dealership is not created or updated.

推荐答案

Eloquent 的 push() 保存了模型和它的关系，但是首先你必须告诉你想在关系中涉及什么.

Eloquent's push() saves the model and its relationships, but first you have to tell what you want to be involved in the relationsship.

由于您的 user-model/table 包含经销商的 id，我假设一个用户只能属于一个经销商，因此关系应该如下所示:

Since your user-model/table holds the id of the dealership, I assume that a user can belong to only one dealership, so the relationship should look like this:

用户模型:

public function dealership()
{
  return $this->belongsTo('Dealership');
}

经销商模式:

public function users()
{
  return $this->hasMany('User');
}

要从经销商角度保存用户，请执行以下操作:

To save a User from the Dealership perspective, you do this:

$dealership->users()->save($user);

要将经销商与用户关联，请执行以下操作:

To associate a dealership with a user, you do this:

$user->dealership()->associate($dealership);
$user->save();
