使用

创建模型

创建您的模型,但重要的是要定义可以从输入表单数据中填充的属性。

namespace App;

class Post extends Eloquent { // or Ardent, Or any other Model Class

    protected $fillable = [
        'title',
        'author',
        ...
     ];

     ...
}

创建仓库

namespace App;

use SOSTheBlack\Repository\Eloquent\BaseRepository;

class PostRepository extends BaseRepository {

    /**
     * Specify Model class name
     *
     * @return string
     */
    function model()
    {
        return "App\\Post";
    }
}

生成器

通过生成器轻松创建您的仓库。

配置

您必须首先配置存储库文件的存储位置。默认情况下是“app”文件夹和命名空间“App”。请注意,paths数组中的值实际上同时用作命名空间和文件路径。不过,在生成过程中会自动处理前后斜杠。

    ...
    'generator'=>[
        'basePath'=>app()->path(),
        'rootNamespace'=>'App\\',
        'paths'=>[
            'models'       => 'Entities',
            'repositories' => 'Repositories',
            'interfaces'   => 'Repositories',
            'transformers' => 'Transformers',
            'presenters'   => 'Presenters',
            'validators'   => 'Validators',
            'controllers'  => 'Http/Controllers',
            'provider'     => 'RepositoryServiceProvider',
            'criteria'     => 'Criteria',
        ]
    ]

您可能希望将项目文件夹的根目录放置在“app”之外,并添加另一个命名空间,例如

    ...
     'generator'=>[
        'basePath'      => base_path('src/Lorem'),
        'rootNamespace' => 'Lorem\\'
    ]

此外,您可能希望自定义生成的类保存的位置。这可以通过编辑paths节点来完成。例如

    'generator'=>[
        'basePath'=>app()->path(),
        'rootNamespace'=>'App\\',
        'paths'=>[
            'models'=>'Models',
            'repositories'=>'Repositories\\Eloquent',
            'interfaces'=>'Contracts\\Repositories',
            'transformers'=>'Transformers',
            'presenters'=>'Presenters'
            'validators'   => 'Validators',
            'controllers'  => 'Http/Controllers',
            'provider'     => 'RepositoryServiceProvider',
            'criteria'     => 'Criteria',
        ]
    ]

命令

要生成您模型所需的所有内容,请运行以下命令

php artisan make:entity Post

这将创建控制器、验证器、模型、存储库、演示者和转换类。它还将创建一个新的服务提供者,用于将Eloquent存储库与其对应的存储库接口绑定。要加载它,只需将以下内容添加到您的AppServiceProvider的@register方法中

    $this->app->register(RepositoryServiceProvider::class);

您也可以从repository命令传递选项,因为该命令只是一个包装器。

要为您的Post模型生成存储库,请使用以下命令

php artisan make:repository Post

要为具有Blog命名空间的Post模型生成存储库,请使用以下命令

php artisan make:repository "Blog\Post"

添加可填充的字段

php artisan make:repository "Blog\Post" --fillable="title,content"

要直接与您的命令一起添加验证规则,您需要传递--rules选项并创建迁移

php artisan make:entity Cat --fillable="title:string,content:text" --rules="title=>required|min:2, content=>sometimes|min:10"

该命令还会创建您的基本RESTful控制器,因此只需将此行添加到您的routes.php文件中,您就可以拥有基本的CRUD操作

Route::resource('cats', CatsController::class);

在运行命令时,您将在您设置的默认文件夹内创建“Entities”文件夹和“Repositories”。

现在完成后,您仍然需要将其实际存储库的接口绑定,例如在您的自己的Repositories Service Provider中。

App::bind('{YOUR_NAMESPACE}Repositories\PostRepository', '{YOUR_NAMESPACE}Repositories\PostRepositoryEloquent');

然后使用

public function __construct({YOUR_NAMESPACE}Repositories\PostRepository $repository){
    $this->repository = $repository;
}

或者,您可以使用Artisan命令来自动绑定。

php artisan make:bindings Cats

使用方法

namespace App\Http\Controllers;

use App\PostRepository;

class PostsController extends BaseController {

    /**
     * @var PostRepository
     */
    protected $repository;

    public function __construct(PostRepository $repository){
        $this->repository = $repository;
    }

    ....
}

在存储库中查找所有结果

$posts = $this->repository->all();

在存储库中带有分页的查找所有结果

$posts = $this->repository->paginate($limit = null, $columns = ['*']);

按id查找结果

$post = $this->repository->find($id);

隐藏模型属性

$post = $this->repository->hidden(['country_id'])->find($id);

仅显示模型的具体属性

$post = $this->repository->visible(['id', 'state_id'])->find($id);

加载模型关系

$post = $this->repository->with(['state'])->find($id);

按字段名查找结果

$posts = $this->repository->findByField('country_id','15');

按多个字段查找结果

$posts = $this->repository->findWhere([
    //Default Condition =
    'state_id'=>'10',
    'country_id'=>'15',

    //Custom Condition
    ['columnName1','>','10'],

    //DATE, DAY, MONTH, YEAR
    ['columnName2','DATE','2021-07-02'], //whereDate
    ['columnName3','DATE >=','2021-07-02'], //whereDate with operator

    ['columnName4','IN',['value1','value2']], //whereIn
    ['columnName5','NOTIN',['value1','value2']], //whereNotIn
    ['columnName6','EXIST',''], //whereExists

    //HAS, HASMORPH, DOESNTHAVE, DOESNTHAVEMORPH
    ['columnName7','HAS',function($query){}], //whereHas

    //BETWEEN, BETWEENCOLUMNS, NOTBETWEEN, NOTBETWEENCOLUMNS
    ['columnName8','BETWEEN',[10, 100]], //whereBetween
]);

在一个字段中按多个值查找结果

$posts = $this->repository->findWhereIn('id', [1,2,3,4,5]);

在一个字段中按多个值排除查找结果

$posts = $this->repository->findWhereNotIn('id', [6,7,8,9,10]);

使用自定义范围查找所有结果

$posts = $this->repository->scopeQuery(function($query){
    return $query->orderBy('sort_order','asc');
})->all();

在存储库中创建新条目

$post = $this->repository->create( Input::all() );

在存储库中更新条目

$post = $this->repository->update( Input::all(), $id );

在存储库中删除条目

$this->repository->delete($id)

按多个字段删除存储库中的条目

$this->repository->deleteWhere([
    //Default Condition =
    'state_id'=>'10',
    'country_id'=>'15',
])

创建查询条件

使用命令

php artisan make:criteria MyCriteria

标准是按照您的需求应用特定条件来更改查询的存储库的方式。您可以在您的存储库中添加多个标准。

use SOSTheBlack\Repository\Contracts\CriteriaInterface;use SOSTheBlack\Repository\Contracts\RepositoryInterface;

class MyCriteria implements CriteriaInterface {

    public function apply($model, RepositoryInterface $repository)
    {
        $model = $model->where('user_id','=', Auth::user()->id );
        return $model;
    }
}

在控制器中使用查询条件

namespace App\Http\Controllers;

use App\PostRepository;

class PostsController extends BaseController {

    /**
     * @var PostRepository
     */
    protected $repository;

    public function __construct(PostRepository $repository){
        $this->repository = $repository;
    }


    public function index()
    {
        $this->repository->pushCriteria(new MyCriteria1());
        $this->repository->pushCriteria(MyCriteria2::class);
        $posts = $this->repository->all();
		...
    }

}

从标准中获取结果

$posts = $this->repository->getByCriteria(new MyCriteria());

在存储库中设置默认标准

use SOSTheBlack\Repository\Eloquent\BaseRepository;

class PostRepository extends BaseRepository {

    public function boot(){
        $this->pushCriteria(new MyCriteria());
        // or
        $this->pushCriteria(AnotherCriteria::class);
        ...
    }

    function model(){
       return "App\\Post";
    }
}

跳过存储库中定义的标准

在任何其他链式方法之前使用skipCriteria

$posts = $this->repository->skipCriteria()->all();

弹出标准

使用popCriteria来删除一个标准

$this->repository->popCriteria(new Criteria1());
// or
$this->repository->popCriteria(Criteria1::class);

使用请求查询条件

RequestCriteria是标准的标准实现。它允许从请求发送的参数中执行过滤。

您可以执行动态搜索、过滤数据并自定义查询。

要在您的存储库中使用标准,您可以在存储库的boot方法中添加一个新的标准,或者直接在控制器中使用,以便过滤出只有少数请求。

在仓库中启用

use SOSTheBlack\Repository\Eloquent\BaseRepository;


class PostRepository extends BaseRepository {

	/**
     * @var array
     */
    protected $fieldSearchable = [
        'name',
        'email'
    ];

    public function boot(){
        $this->pushCriteria(app('SOSTheBlack\Repository\Criteria\RequestCriteria'));
        ...
    }

    function model(){
       return "App\\Post";
    }
}

记住,您需要定义模型中哪些字段可以搜索。

在您的存储库中,将$fieldSearchable设置为可搜索的字段的名称或与字段的关系。

protected $fieldSearchable = [
	'name',
	'email',
	'product.name'
];

您可以为执行查询的查询设置条件类型,默认条件是“=”。

protected $fieldSearchable = [
	'name'=>'like',
	'email', // Default Condition "="
	'your_field'=>'condition'
];

在控制器中启用

	public function index()
    {
        $this->repository->pushCriteria(app('SOSTheBlack\Repository\Criteria\RequestCriteria'));
        $posts = $this->repository->all();
		...
    }

标准示例

按请求获取所有数据,不进行过滤

http://sostheblack.local/users

[
    {
        "id": 1,
        "name": "John Doe",
        "email": "john@gmail.com",
        "created_at": "-0001-11-30 00:00:00",
        "updated_at": "-0001-11-30 00:00:00"
    },
    {
        "id": 2,
        "name": "Lorem Ipsum",
        "email": "lorem@ipsum.com",
        "created_at": "-0001-11-30 00:00:00",
        "updated_at": "-0001-11-30 00:00:00"
    },
    {
        "id": 3,
        "name": "Laravel",
        "email": "laravel@gmail.com",
        "created_at": "-0001-11-30 00:00:00",
        "updated_at": "-0001-11-30 00:00:00"
    }
]

在存储库中执行研究

http://sostheblack.local/users?search=John%20Doe

或者

http://sostheblack.local/users?search=John&searchFields=name:like

或者

http://sostheblack.local/users?search=john@gmail.com&searchFields=email:=

或者

http://sostheblack.local/users?search=name:John Doe;email:john@gmail.com

或者

http://sostheblack.local/users?search=name:John;email:john@gmail.com&searchFields=name:like;email:=

[
    {
        "id": 1,
        "name": "John Doe",
        "email": "john@gmail.com",
        "created_at": "-0001-11-30 00:00:00",
        "updated_at": "-0001-11-30 00:00:00"
    }
]

您可以使用“search”参数而不必使用完整的“searchFields”参数。

http://sostheblack.local/users?search=id:2;age:17;email:john@gmail.com&searchFields='id':=

默认情况下,RequestCriteria使用每个查询参数的OR比较运算符进行查询。http://sostheblack.local/users?search=age:17;email:john@gmail.com

上述示例将执行以下查询

SELECT * FROM users WHERE age = 17 OR email = 'john@gmail.com';

要使用AND进行查询,请传递以下searchJoin参数

http://sostheblack.local/users?search=age:17;email:john@gmail.com&searchJoin=and

过滤字段

http://sostheblack.local/users?filter=id;name

[
    {
        "id": 1,
        "name": "John Doe"
    },
    {
        "id": 2,
        "name": "Lorem Ipsum"
    },
    {
        "id": 3,
        "name": "Laravel"
    }
]

排序结果

http://sostheblack.local/users?filter=id;name&orderBy=id&sortedBy=desc

[
    {
        "id": 3,
        "name": "Laravel"
    },
    {
        "id": 2,
        "name": "Lorem Ipsum"
    },
    {
        "id": 1,
        "name": "John Doe"
    }
]

       }
   ]

覆盖参数名称

您可以在配置文件config/repository.php中更改参数的名称。

缓存

轻松为您的仓库添加一层缓存

缓存使用

实现CacheableInterface接口并使用CacheableRepository特性。

use SOSTheBlack\Repository\Contracts\CacheableInterface;use SOSTheBlack\Repository\Eloquent\BaseRepository;use SOSTheBlack\Repository\Traits\CacheableRepository;

class PostRepository extends BaseRepository implements CacheableInterface {

    use CacheableRepository;

    ...
}

完成,这样您的仓库就会被缓存,并且每当创建、修改或删除项目时,都会清除仓库缓存。

缓存配置

您可以在文件config/repository.php中更改缓存设置,也可以直接在您的仓库上更改。

config/repository.php

'cache'=>[
    //Enable or disable cache repositories
    'enabled'   => true,

    //Lifetime of cache
    'minutes'   => 30,

    //Repository Cache, implementation Illuminate\Contracts\Cache\Repository
    'repository'=> 'cache',

    //Sets clearing the cache
    'clean'     => [
        //Enable, disable clearing the cache on changes
        'enabled' => true,

        'on' => [
            //Enable, disable clearing the cache when you create an item
            'create'=>true,

            //Enable, disable clearing the cache when upgrading an item
            'update'=>true,

            //Enable, disable clearing the cache when you delete an item
            'delete'=>true,
        ]
    ],
    'params' => [
        //Request parameter that will be used to bypass the cache repository
        'skipCache'=>'skipCache'
    ],
    'allowed'=>[
        //Allow caching only for some methods
        'only'  =>null,

        //Allow caching for all available methods, except
        'except'=>null
    ],
],

您可以直接在仓库中覆盖这些设置。

use SOSTheBlack\Repository\Contracts\CacheableInterface;use SOSTheBlack\Repository\Eloquent\BaseRepository;use SOSTheBlack\Repository\Traits\CacheableRepository;

class PostRepository extends BaseRepository implements CacheableInterface {

    // Setting the lifetime of the cache to a repository specifically
    protected $cacheMinutes = 90;

    protected $cacheOnly = ['all', ...];
    //or
    protected $cacheExcept = ['find', ...];

    use CacheableRepository;

    ...
}

可缓存的函数有:all、paginate、find、findByField、findWhere、getByCriteria

验证器

需要sostheblack/laravel-validatorcomposer require sostheblack/laravel-validator

使用sostheblack/laravel-validator进行简单的验证

有关更多详细信息,请点击此处

使用验证器类

创建验证器

在下面的示例中,我们为创建和编辑定义了一些规则

use SOSTheBlack\Repository\Validators\LaravelValidator;

class PostValidator extends LaravelValidator {

    protected $rules = [
        'title' => 'required',
        'text'  => 'min:3',
        'author'=> 'required'
    ];

}

要定义特定规则,请按照以下步骤操作

use SOSTheBlack\Repository\Contracts\ValidatorInterface;
use SOSTheBlack\Repository\Validators\LaravelValidator;

class PostValidator extends LaravelValidator {

    protected $rules = [
        ValidatorInterface::RULE_CREATE => [
            'title' => 'required',
            'text'  => 'min:3',
            'author'=> 'required'
        ],
        ValidatorInterface::RULE_UPDATE => [
            'title' => 'required'
        ]
   ];

}
在仓库中启用验证器
use SOSTheBlack\Repository\Eloquent\BaseRepository;

class PostRepository extends BaseRepository {

    /**
     * Specify Model class name
     *
     * @return mixed
     */
    function model(){
       return "App\\Post";
    }

    /**
     * Specify Validator class name
     *
     * @return mixed
     */
    public function validator()
    {
        return "App\\PostValidator";
    }
}

在仓库中定义规则

或者,您可以直接将规则设置到rules仓库属性中,而不是使用类来定义验证规则,这将与Validation类具有相同的效果。

use SOSTheBlack\Repository\Contracts\ValidatorInterface;use SOSTheBlack\Repository\Eloquent\BaseRepository;

class PostRepository extends BaseRepository {

    /**
     * Specify Validator Rules
     * @var array

     protected $rules = [

}

验证现在已就绪。如果失败,将抛出类型为SOSTheBlack\Repository\Exceptions\ValidatorException的异常。

表示器

演示器作为对象的包装器和渲染器。

Fractal表示器

需要Fractalcomposer require league/fractal

实现演示器有两种方式,第一种是创建一个TransformerAbstract并使用您的演示器类,如创建Transformer类中所述。

第二种方式是使您的模型实现Transformable接口,并使用默认的演示器ModelFractarPresenter,这将产生相同的效果。

转换器类
使用以下命令创建转换器
php artisan make:transformer Post

这将生成以下类。

创建转换器类
use League\Fractal\TransformerAbstract;

class PostTransformer extends TransformerAbstract
{
    public function transform(\Post $post)
    {
        return [
            'id'      => (int) $post->id,
            'title'   => $post->title,
            'content' => $post->content
        ];
    }
}
使用以下命令创建演示器
php artisan make:presenter Post

如果您尚未创建转换器,命令将提示您创建转换器。

创建演示器
use SOSTheBlack\Repository\Presenter\FractalPresenter;

class PostPresenter extends FractalPresenter {

    /**
     * Prepare data to present
     *
     * @return \League\Fractal\TransformerAbstract
     */
    public function getTransformer()
    {
        return new PostTransformer();
    }
}
在仓库中启用
use SOSTheBlack\Repository\Eloquent\BaseRepository;

class PostRepository extends BaseRepository {

    ...

    public function presenter()
    {
        return "App\\Presenter\\PostPresenter";
    }
}

或者,在您的控制器中启用它

$this->repository->setPresenter("App\\Presenter\\PostPresenter");
从模型使用演示器后

如果您记录了演讲者并且有时使用了 skipPresenter() 方法,或者您不想自动由演讲者更改结果。您可以在您的模型上实现 Presentable 接口,这样您就可以在任何时候展示您的模型。请看下面的示例。

在您的模型中实现接口 SOSTheBlack\Repository\Contracts\PresentableSOSTheBlack\Repository\Traits\PresentableTrait

namespace App;

use SOSTheBlack\Repository\Contracts\Presentable;use SOSTheBlack\Repository\Traits\PresentableTrait;

class Post extends Eloquent implements Presentable {

    use PresentableTrait;

    protected $fillable = [
        'title',
        'author',
        ...
     ];

     ...
}

现在,您可以单独提交您的模型,请看以下示例

$repository = app('App\PostRepository');
$repository->setPresenter("SOSTheBlack\\Repository\\Presenter\\ModelFractalPresenter");

//Getting the result transformed by the presenter directly in the search
$post = $repository->find(1);

print_r( $post ); //It produces an output as array

...

//Skip presenter and bringing the original result of the Model
$post = $repository->skipPresenter()->find(1);

print_r( $post ); //It produces an output as a Model object
print_r( $post->presenter() ); //It produces an output as array

您可以在每次访问时跳过演讲者,并直接在模型中使用它,为了实现这一点,在您的仓库中将 $skipPresenter 属性设置为 true

use SOSTheBlack\Repository\Eloquent\BaseRepository;

class PostRepository extends BaseRepository {

    /**
    * @var bool
    */
    protected $skipPresenter = true;

    public function presenter()
    {
        return "App\\Presenter\\PostPresenter";
    }
}
模型类
实现接口
namespace App;

use SOSTheBlack\Repository\Contracts\Transformable;

class Post extends Eloquent implements Transformable {
     ...
     /**
      * @return array
      */
     public function transform()
     {
         return [
             'id'      => (int) $this->id,
             'title'   => $this->title,
             'content' => $this->content
         ];
     }
}
在仓库中启用

SOSTheBlack\Repository\Presenter\ModelFractalPresenter 是为实现了 Transformable 的模型提供的默认演讲者

use SOSTheBlack\Repository\Eloquent\BaseRepository;

class PostRepository extends BaseRepository {

    ...

    public function presenter()
    {
        return "SOSTheBlack\\Repository\\Presenter\\ModelFractalPresenter";
    }
}

或者,在您的控制器中启用它

$this->repository->setPresenter("SOSTheBlack\\Repository\\Presenter\\ModelFractalPresenter");

在仓库中定义跳过演讲者

在任何其他链式方法之前使用 skipPresenter

$posts = $this->repository->skipPresenter()->all();

或者

$this->repository->skipPresenter();

$posts = $this->repository->all();
