改进DRY数据库

索引

• 安装
• 用法

安装

composer require tallieutallieu/dry-dbi

用法

定义服务提供者

<?php

namespace app\provider;

use Repository\PageRepository;
use Oak\Contracts\Container\ContainerInterface;
use Oak\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
	public function register(ContainerInterface $app)
	{
		$app->set(Repository\PageRepository::class, Repository\PageRepository::class);
	}
	
	public function boot(ContainerInterface $app)
	{
	    //
	}
}

仓库定义

从BaseRepository扩展以实现某些默认行为。

<?php

namespace Repository;

use Tnt\Dbi\BaseRepository;
use Model\Page;

class PageRepository extends BaseRepository
{
	protected $model = Page::class;
	
	/**
	* Initial method for default actions
	*/
	public function init()
	{
		$this->addCriteria( new OrderBy( 'sort_index' ) );
	}
	
	public function visible()
	{
		$this->addCriteria( new IsTrue( 'is_visible' ) );
		
		return $this;
	}
	
	/**
	* Use querybuilder directly for custom actions
	*/
	public function types(array $types)
	{
		$this->useQueryBuilder(function(QueryBuilder $queryBuilder) use ($types) {

			$queryBuilder->whereGroup(function(QueryBuilder $queryBuilder) use ($types) {
				foreach ($types as $type) {
					$queryBuilder->where('type', '=', $type->id, 'OR');
				}
			});
		});

		return $this;
	}
	
	/**
	* Use querybuilder for table joins (left, right, inner)
	*/
	public function expertise(Expertise $expertise)
   	{
		$this->useQueryBuilder(function(QueryBuilder $queryBuilder) {
		    $queryBuilder->leftJoin('project_expertise')->on('project', '=', 'project.id');
		});

		return $this;
	    }
}

使用仓库

<?php

namespace Controller;

use app\container\Application;

class pages
{
    public static function get(Request $request)
    {
        $app = Application::get();
        $pageRepository = $app->get(PageRepository::class);
        
        $visiblePages = $pageRepository->visible()->get();
    }
}
