# 王者战队-简单Repositories

数据库抽象层,for Hyperf v1.1.x. 仅在私有库内使用,请先配置composer.json私有库地址,并忽略https校验.

## Installation

## composer.json 配置
在composer.json内追加以下配置，告诉composer.json我们需要走私有库
```json
   "repositories": [
        {
            "type": "composer",
            "url": "http://composer.ipx.mx"
        }
    ],
    "config": {
        "preferred-install": "dist",
        "disable-tls": true,
        "secure-http": false
    }
```

## 安装

 ```bash
 composer require "kz2/repositories" -vvv
 ```


## 试用方式

第一步, 创建你的仓库类文件. 这个类文件必须继承 ```KZ2\Repositories\Model\Repository``` 同时 实现 ``` model() ``` 方法

```php
<?php namespace App\Repositories;

use KZ2\Repositories\Model\Repository;

class UserRepository extends Repository {

    public function model() {
        return 'App\Model\User';
    }
}
```

同时要创建对应的Model ```App\Model\User``` :

最后，在你的控制器内调用仓库.
And finally, use the repository in the controller:

```php
<?php namespace App\Http\Controllers;

use App\Repositories\UserRepository as UserRepo;

class UserController extends Controller {

    private $user;

    public function __construct(UserRepo $user) {

        $this->user = $user;
    }

    public function index() {
        return json_success($this->user->all());
    }
}
```

## 可用的方法

##### KZ2\Repositories\Contracts\RepositoryInterface

```php
public function all($columns = array('*'))
public function lists($value, $key = null)
public function paginate($perPage = 1, $columns = array('*'), $page = 1, $pageName = 'page');
public function create(array $data)
// if you use mongodb then you'll need to specify primary key $attribute
public function update(array $data, $id, $attribute = "id")
public function delete($id)
public function find($id, $columns = array('*'))
public function findBy($field, $value, $columns = array('*'))
public function findAllBy($field, $value, $columns = array('*'))
public function findWhere($where, $columns = array('*'))
```

##### KZ2\Repositories\Contracts\CriteriaInterface

```php
public function apply($model, Repository $repository)
```

### 用例样本


创建一个数据.

```php
$this->film->create(Input::all());
```

更新已经存在的数据.

```php
$this->film->update(Input::all(), $film_id);
```

根据主键删除数据.

```php
$this->film->delete($id);
```

根据主键查找数据.

```php
$this->film->find($id);
```

你也可以选择某些字段返回

```php
$this->film->find($id, ['title', 'description', 'release_date']);
```

获取单个字段下的一行数据

```php
$this->film->findBy('title', $title);
```

或者你可以获取单个字段的所有数据行.
```php
$this->film->findAllBy('author_id', $author_id);
```

获取指定字段多行数据.

```php
$this->film->findWhere([
    'author_id' => $author_id,
    ['year','>',$year]
]);
```

## Criteria

Criteria 是一个具体链式应用实际条件或者查询. 你的criteria必须实现```KZ2\Repositories\Criteria\Criteria```抽象类.


使用标准的样本

```php
<?php namespace App\Repositories\Criteria\Films;

use KZ2\Repositories\Criteria\Criteria;
use KZ2\Repositories\Contracts\RepositoryInterface as Repository;

class LengthOverTwoHours extends Criteria {

    /**
     * @param $model
     * @param RepositoryInterface $repository
     * @return mixed
     */
    public function apply($model, Repository $repository)
    {
        $model = $model->where('length', '>', 120);
        return $model;
    }
}
```


```php
<?php namespace App\Http\Controllers;

use App\Repositories\Criteria\Films\LengthOverTwoHours;
use App\Repositories\FilmsRepository as Film;

class FilmsController extends Controller {

    /**
     * @var Film
     */
    private $film;

    public function __construct(Film $film) {

        $this->film = $film;
    }

    public function index() {
        $this->film->pushCriteria(new LengthOverTwoHours());
        return \Response::json($this->film->all());
    }
}
```
