README

A Laravel package that add some custom scopes on models to make a better selection via requests

Installation

With composer

composer require NastuzziSamy/laravel-query-selector

Docs

This trait add multiple scopes into model class They are all usable directly by calling them (withtout the "scope" behind) when querying for items

To work correctly, the developer must define this property:

• selection as a key/value array => the developer defines as selectors as (s)he wants, but a selector is only usable if it is defined as key => each key is a selector: paginate, week, order... => each value can be
  • a simple value (which is treated as like a default value)
  • an array with (if needed) a default key. Next, each selector as its column params => if the default value is null or it is not defined if the array, this means that the selector is optional

Usage

In your targeted model:

<?php

namespace \App\Models;

use Illuminate\Database\Eloquent\Model;
use NastuzziSamy\Laravel\Traits\HasSelection;

class User extends Model {
    use HasSelection;

    // Example of selection definition
    protected $selection = [
        'paginate'  => 2, // 2 users per page by default
        'order'     => [
            'default' => 'latest',
            'columns' => [
                'creation'  => 'id' // We set our column to order our data
            ]
        ]
    ];

    /* ... */
}

In your targeted controller:

<?php

namespace \App\Http\Controllers;

use Illuminate\Routing\Controller;
use App\Models\User;

class UserController extends Controller {
    /* ... */

    public function index() {
        return response->json(
            User::getSelection()
        );
    }

    /* ... */
}

Let think we got 11 users, the 11th is the latest

Example 1: request /api/users?paginate=5

Output:

[
    {
        "id": 11,
        "name": "11"
    },
    {
        "id": 10,
        "name": "10"
    },
    {
        "id": 9,
        "name": "9"
    },
    {
        "id": 8,
        "name": "8"
    },
    {
        "id": 7,
        "name": "7"
    },
]

Example 2: request /api/users?paginate=3&order=random

Output:

[
    {
        "id": 4,
        "name": "4"
    },
    {
        "id": 10,
        "name": "10"
    },
    {
        "id": 3,
        "name": "3"
    },
]

Custom: You can also use your custom scopes !!

If you have installed the nastuzzi-samy\laravel-model-stages for example

Usage example

In your targeted model:

<?php

namespace \App\Models;

use Illuminate\Database\Eloquent\Model;
use NastuzziSamy\Laravel\Traits\HasSelection;
use NastuzziSamy\Laravel\Traits\HasStages;

class User extends Model {
    use HasSelection, HasStages;

    protectec $selection = [
        'stage' => null, // Optional selector because default value is null
        'stages' => [], // Array option but no default value
        'order' => 'oldest',
    ];

    /* ... */
}

In your targeted controller:

<?php

namespace \App\Http\Controllers;

use Illuminate\Routing\Controller;
use App\Models\User;

class UserController extends Controller {
    /* ... */

    public function index($request) {
        return response->json(
            User::getSelection()
        );
    }

    /* ... */
}

Let think we got a company tree with 1 Boss, 2 Supervisors and 4 Employees

Example 1: request /api/users?stage=0

Output:

[
    {
        "id": 1,
        "name": "Boss",
        "parent_id": null
    },
]

Example 2: request /api/users?stage=0,1

Output:

[
    {
        "id": 1,
        "name": "Boss",
        "parent_id": null
    },
    {
        "id": 2,
        "name": "Supervisor 1",
        "parent_id": 1
    },
    {
        "id": 3,
        "name": "Supervisor 2",
        "parent_id": 1
    },
]

Example 3: request /api/users?stage=2&order=random

Output:

[
    {
        "id": 6,
        "name": "Employee 3",
        "parent_id": 3
    },
    {
        "id": 4,
        "name": "Employee 1",
        "parent_id": 2
    },
    {
        "id": 7,
        "name": "Employee 4",
        "parent_id": 3
    },
    {
        "id": 5,
        "name": "Employee 2",
        "parent_id": 2
    },
]
