Laravel - 用户表,使 id uuid 类型

3 uuid factory laravel laravel-5 laravel-5.8

1- 用户表,使 id uuid 类型。

没问题

php artisan migrate:refresh
Run Code Online (Sandbox Code Playgroud)

但是这个错误

php artisan db:seed
Run Code Online (Sandbox Code Playgroud)

错误:(“SQLSTATE[HY000]:一般错误:1364 字段‘id’没有默认值”)

2- 公司也希望随机分配给用户。在用户表中,uuid 类型将保存在 user_id 列中。

谢谢你从现在...

用户模型:

use UsesUuid;

protected $fillable = ['name', 'email', 'password', 'role', 'slug',];

protected $hidden = ['password', 'remember_token',];

protected $casts = ['email_verified_at' => 'datetime',];

public function companies()
{
    return $this->hasMany('App\Company', 'user_id', 'id');
}

使用 Uuid 特性:

protected static function boot()
{
    parent::boot();

    static::creating(function ($post) {
        $post->{$post->getKeyName()} = (string)Str::uuid();
    });
}

public $incrementing = false;

public function getKeyType()
{
    return 'string';
}

用户迁移:

Schema::create('users', function (Blueprint $table) {
        $table->uuid('id')->primary()->unique();
        $table->string('name',100);
        $table->string('email',100);
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password',100);
        $table->string('role',20)->nullable();
        $table->string('slug',100);
        $table->rememberToken();
        $table->timestamps();
        $table->softDeletes();
    });

公司迁移:

Schema::create('companies', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('user_id',36);
$table->string('name', 100);

$table->timestamps();
$table->softDeletes();

$table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');

用户工厂:

$name = $faker->name;
return [
    'id' => Str::uuid(),
    'name' => $name,
    'email' => $faker->unique()->safeEmail,
    'email_verified_at' => now(),
    'password' => Hash::make(123), // password
    'remember_token' => Str::random(10),
    'role' => 'user',
    'slug' => Str::slug($name),
];

像这样修改你的特征:

static::creating(function ($post) {
    empty($post->{$post->getKeyName()}) && $post->{$post->getKeyName()} = (string)Str::uuid();
});

在您的迁移中,无需使 UUID 唯一,因为它已经是唯一的!

$table->uuid('id');
$table->primary('id');

并且工厂必须自己创建主 UUID,不要自己添加

我认为随着这些变化,播种机必须成功运行
