Json Driver for Cakephp3

An Json datasource for CakePHP 3.5

Installing via composer

Install composer and run:

composer require giginc/cakephp3-driver-json

Defining a connection

Now, you need to set the connection in your config/app.php file:

 'Datasources' => [
    'default' => [
        'className' => 'Giginc\Json\Database\Connection',
        'driver' => 'Giginc\Json\Database\Driver\Json',
        'baseDir' => './', // local path on the server relative to WWW_ROOT
    ],
],

Models

After that, you need to load Giginc\Json\ORM\Table in your tables class:

//src/Model/Table/YourTable.php

use Giginc\Json\ORM\Table;

class CategoriesTable extends Table {

    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config)
    {
        parent::initialize($config);

        $this->setTable('categories'); // load file is WWW_ROOT/categories.json
    }

}

Controllers

namespace App\Controller;

use App\Controller\AppController;

/**
 * Pages Controller
 *
 * @property \App\Model\Table\PagesTable $Pages
 *
 * @method \App\Model\Entity\Review[]|\Cake\Datasource\ResultSetInterface paginate($object = null, array $settings = [])
 */
class PagesController extends AppController
{
    /**
     * Index method
     *
     * @return \Cake\Http\Response|void
     */
    public function index()
    {
        $this->loadModel('TestJsons');
        $data = $this->TestJsons->find()
            ->where('code', '=', "0001")
            ->get()
            ;
    }
}

You can start Query your data using the various query methods such as find, where, orWhere, whereIn, whereStartsWith, whereEndsWith, whereContains and so on. Also you can aggregate your data after query using sum, count, groupBy, max, min etc.

Let's see a quick example:

//data.json
{
	"name": "products",
	"description": "Features product list",
	"vendor":{
		"name": "Computer Source BD",
		"email": "info@example.com",
		"website":"www.example.com"
	},
	"users":[
		{"id":1, "name":"Johura Akter Sumi", "location": "Barisal"},
		{"id":2, "name":"Mehedi Hasan Nahid", "location": "Barisal"},
		{"id":3, "name":"Ariful Islam", "location": "Barisal"},
		{"id":4, "name":"Suhel Ahmed", "location": "Sylhet"},
		{"id":5, "name":"Firoz Serniabat", "location": "Gournodi"},
		{"id":6, "name":"Musa Jewel", "location": "Barisal", "visits": [
			{"name": "Sylhet", "year": 2011},
			{"name": "Cox's Bazar", "year": 2012},
			{"name": "Bandarbar", "year": 2014}
		]}
	],
	"products": [
		{"id":1, "user_id": 2, "city": "bsl", "name":"iPhone", "cat":1, "price": 80000},
		{"id":2, "user_id": 2, "city": null, "name":"macbook pro", "cat": 2, "price": 150000},
		{"id":3, "user_id": 2, "city": "dhk", "name":"Redmi 3S Prime", "cat": 1, "price": 12000},
		{"id":4, "user_id": 1, "city": null, "name":"Redmi 4X", "cat":1, "price": 15000},
		{"id":5, "user_id": 1, "city": "bsl", "name":"macbook air", "cat": 2, "price": 110000},
		{"id":6, "user_id": 2, "city": null, "name":"macbook air 1", "cat": 2, "price": 81000}
	]
}

$this->loadModel('TestJsons');
$data = $this->TestJsons->find('products')
    ->where('cat', '=', 2)
    ->get();
dd($res);

//This will print
/*
array:3 [▼
  1 => {#7 ▼
    +"id": 2
    +"user_id": 2
    +"city": null
    +"name": "macbook pro"
    +"cat": 2
    +"price": 150000
  }
  4 => {#8 ▼
    +"id": 5
    +"user_id": 1
    +"city": "bsl"
    +"name": "macbook air"
    +"cat": 2
    +"price": 110000
  }
  5 => {#9 ▼
    +"id": 6
    +"user_id": 2
    +"city": null
    +"name": "macbook air 1"
    +"cat": 2
    +"price": 81000
  }
]
