README

如果你想要使用uuid列并自动填充它们,这个包就是为你准备的。

这是一个Laravel包,用于在模型中使用(自动生成)uuid。使用这个包,你可以写更少的代码,因为uuid在第一次保存实例时就会创建。

文档

Laravel兼容性

安装

通过执行命令将包添加到你的composer.json中。

composer require waska14/laravel-uuid

接下来,在你的config/app.php中添加服务提供者

'providers' => [
    ....
    Waska\LaravelUuid\UuidServiceProvider::class,
    ....
],

迁移

// 2.1 If you want to use uuid column as primary column:
Schema::create('students', function(Blueprint $table)
{
    $table->uuid('uuid')->primary();
    $table->string('name');
    $table->string('last_name');
    ...
});

// 2.2 If you want to use uuid column as non-primary column:
Schema::create('students', function(Blueprint $table)
{
    $table->increments('id');
    $table->uuid('uuid')->unique();
    $table->string('name');
    $table->string('last_name');
    ...
});

// 2.3 If you want to use multiple uuid columns (maybe on of them is primary):
Schema::create('students', function(Blueprint $table)
{
    $table->uuid('uuid')->primary();
    $table->uuid('uuid_column_2')->unique();
    $table->uuid('uuid_column_3')->unique();
    $table->string('name');
    $table->string('last_name');
    ...
});

注意:如果uuid列不是主键,你应该使其唯一,或者手动索引该列。

模型

  1. 必须在模型中使用特质
class Student extends Model
{
    use \Waska\Traits\Uuid;
}

2.1 如果你使用uuid列作为主键且column_name 默认 id,你不需要做更多。

2.2 如果你使用uuid列作为主键且column_name 不是默认 id,你必须定义protected $primaryKeyprotected $uuid_column

class Student extends Model
{
    use \Waska\Traits\Uuid;

    protected $primaryKey = "uuid_primary_column_name";
    protected $uuid_column = "uuid_primary_column_name";

    protected $fillable = [
        'name',
        'last_name',
    ];
}

2.3 如果你使用非主键uuid列且列名等于default_column_name(来自配置的uuid),你只需在protected $fillable中添加列名。

class Student extends Model
{
    use \Waska\Traits\Uuid;

    protected $fillable = [
        'name',
        'last_name',
        'uuid', // config/waska.uuid.php -> default_column_name
    ];
}

2.4 如果你使用非主键uuid列且列名不等于default_column_name(来自配置的uuid),你需要定义protected $uuid_column并在protected $fillable中添加列名。

class Student extends Model
{
    use \Waska\Traits\Uuid;

    protected $uuid_column = "uuid_column_name";
    
    protected $fillable = [
        'name',
        'last_name',
        'uuid_column_name',
    ];
}

2.5 如果你使用多个uuid列(如果其中一个是主键,你必须首先执行步骤2.1),你需要将protected $uuid_column定义为一个数组,并在protected $fillable中添加列名(仅非主键)。

class Student extends Model
{
    use \Waska\Traits\Uuid;

    protected $primaryKey = "uuid_primary_column_name"; // If one of them is primary
    protected $uuid_column = ["uuid_column_name1", "uuid_column_name2", "uuid_column_name3"];
    
    protected $fillable = [
        'name',
        'last_name',
        'uuid_column_name1',
        'uuid_column_name2',
        'uuid_column_name3',
    ];
}

2.6 现在当你创建新的Student对象时,uuid会自动生成。

Student::create([
    'name'      => "Bill',
    'last_name' => "Gates',
]);

// or
$student = new Student([
    'name'      => "Bill',
    'last_name' => "Gates',
]);
$student->save();

// or
$student = new Student();
$student->name = "Bill";
$student->last_name = "Gates";
$student->save();

配置

如果你想更改默认配置,你必须将默认配置文件发布到你的项目中。

你可以在控制台中运行此命令来发布配置

php artisan vendor:publish --tag=waska-uuid-config

注意:如果你打算使用v3v5 uuid,建议将v3_default_namespacev5_default_namespace更改为有效的uuid字符串。

使用tinker中的此命令生成它们(启动tinker:php artisan tinker

Waska\Uuid::get(4); // This command will generate valid uuid (v4, pseudo-random) string

其他使用方法

生成uuid(通用唯一标识符)

/**
 * This generates name-based Uuid
 * @param int $version.
 * @param string $name. String which the uuid is generating for.
 * @param string $namespace. Valid uuid string. Default value is defined in config/waska.uuid.php
 * @return String
 */
Waska\Uuid::get(3, "some_random_string", "valid_uuid");

// This generates pseudo-random Uuid
Waska\Uuid::get(); // Default version is 4, so it means: Waska\Uuid::get(4);

/**
 * This generates name-based Uuid
 * @param int $version.
 * @param string $name. String which the uuid is generating for.
 * @param string $namespace. Valid uuid string. Default value is defined in config/waska.uuid.php
 * @return String
 */
Waska\Uuid::get(5, "some_random_string", "valid_uuid");
