Laravel 10.4 发布

640 2023-03-24 17:04:00

Laravel 团队发布了 v10.4 版本,其中涉及的新特性和变更包括: File::json 方法、将已有的 HasMany 关联转换成 HasOne 关联、一个新的响应断言等。

File::json() 方法

Austin White 贡献了 File::json() 方法,可以快速从文件中获取 JSON 格式的数据:

// 此前
$contents = File::get('sample.json');
$data = json_decode($contents, true);
// 此后
$data = File::json('sample.json');

断言支持媒体类型

Shamimul Alam 贡献了一个断言 helper,用于 415 Unsupported Media Type(415 - 不支持的媒体类型)的响应状态码:

$response->assertUnsupportedMediaType();

将现有的 HasMany 转换成 Hasone

Luke Kuzmish 贡献了将 HasMany 转换成 HasOne、MorphMany 转成 MorphOne 的支持。

下例不得不定义两个关联:

class User extends Model
{
    public function logins(): HasMany {
        return $this->hasMany(Login::class, 'some_id', 'the_other_id');
    }
    public function latestLogin(): HasOne {
        return $this->hasOne(Login::class, 'some_id', 'the_other_id')->latestOfMany();
    }
}

而现在,你可以使用 ->one() 方法实现:

class User extends Model
{
    public function logins(): HasMany {
        return $this->hasMany(Login::class, 'some_id', 'the_other_id');
    }
    public function latestLogin(): HasOne {
        return $this->logins()->one()->latestOfMany();
    }
}

这一 one() 方法在 HasMany, HasManyThrough 和 MorphMany 上都是可用的。

为paginationInformation(分页信息)创建macroable方法

Frans Slabbekoorn 贡献了为 paginationInformation 定义宏的支持,可以在无需从基类资源中为所有资源进行扩展的情况下,自定义分页信息:

/** @mixin \Illuminate\Http\Resources\Json\ResourceCollection */
class ResourceCollectionMixin
{
    public function paginationInformation(): Closure
    {
        return fn ($request, $paginated, $default) => collect($default)->mapWithKeysRecursively(fn ($item, $key) => [Str::camel($key) => $item])->toArray();
    }
}
