README

A simple Collection View for displaying configurable pagination meta data in JSON or XML collection responses. Read more at MixerAPI.com.

Installation

!!! info "" You can skip this step if MixerAPI is installed. However, you will still new to define your viewClasses (read below).

composer require mixerapi/collection-view
bin/cake plugin load MixerApi/CollectionView

Alternatively after composer installing you can manually load the plugin in your Application:

# src/Application.php
public function bootstrap(): void
{
    // other logic...
    $this->addPlugin('MixerApi/CollectionView');
}

Setup

Your controllers must define their view classes for content negotiation.

use MixerApi\CollectionView\View\JsonCollectionView;
use MixerApi\CollectionView\View\XmlCollectionView;

public function viewClasses(): array
{
    return [JsonCollectionView::class, XmlCollectionView::class];
}

This can be done in your AppController to add them to all inheriting controllers or on a controller-by-controller basis.

Usage

That's it, you're done. Perform application/xml or application/json requests as normal. You may also request by .xml or .json extensions (assuming you've enabled them in your config/routes.php). This plugin will only modify collections (e.g. controller::index action) requests, not item (e.g. controller::view action) requests.

Configuration

This is optional. You can alter the names of the response keys, simply create a config/collection_view.php file. Using the example below we can change the collection key to pagination, data to items, and alter some key names within our new pagination object. Just keep the mapped items {{names}} as-is.

# config/collection_view.php
return [
    'CollectionView' => [
        'pagination' => '{{collection}}', // array that holds pagination data
        'pagination.url' => '{{url}}', // url of current page
        'pagination.count' => '{{count}}', // items on the page
        'pagination.total' => '{{total}}', // total database records
        'pagination.pages' => '{{pages}}', // total pages
        'pagination.next' => '{{next}}', // next page url
        'pagination.prev' => '{{prev}}', // previous page url
        'pagination.first' => '{{first}}', // first page url
        'pagination.last' => '{{last}}', // last page url
        'items' => '{{data}}', // the collection of data
    ]
];
