This module provides the classes for serving Doctrine resources for Apigility. It is independent so the ability to create Doctrine resources is independent of the ability to serve those resources.

Installation of this module uses composer. For composer documentation, please refer to getcomposer.org.

$ php composer.phar require zfcampus/zf-apigility-doctrine-server:dev-master

Add ZF\Apigility\Doctrine\Server to your modules

The API created with this library implements full featured and paginated collection resources. A collection is returned from a GET call to a entity endpoint without specifying the id. e.g. GET /api/data_module/entity/user_data

Reserved GET variables

    orderBy
    query

Sort by columnOne ascending

    /api/user_data?orderBy%5BcolumnOne%5D=ASC

Sort by columnOne ascending then columnTwo decending

    /api/user_data?orderBy%5BcolumnOne%5D=ASC&orderBy%5BcolumnTwo%5D=DESC

Queries are not simple key=value pairs. The query parameter is a key-less array of query definitions. Each query definition is an array and the array values vary for each query type.

Each query type requires at a minimum a 'type' and a 'field'. Each query may also specify a 'where' which can be either 'and' or 'or'. Embedded logic such as and(x or y) is not supported.

Building HTTP GET query with PHP. Use this to help build your queries.

PHP Example

    echo http_build_query(
        array(
            'query' => array(
                array('field' =>'cycle', 'where' => 'and', 'type'=>'between', 'from' => 1, 'to'=>100),
                array('field'=>'cycle', 'where' => 'and', 'type' => 'decimation', 'value' => 10)
            ),
            'orderBy' => array('columnOne' => 'ASC', 'columnTwo' => 'DESC')
        )
    );

Javascript Example

$(function() {
    $.ajax({
        url: "http://localhost:8081/api/db/entity/user_data",
        type: "GET",
        data: {
            'query': [
            {
                'field': 'cycle',
                'where': 'and',
                'type': 'between',
                'from': '1',
                'to': '100'
            },
            {
                'field': 'cycle',
                'where': 'and',
                'type': 'decimation',
                'value': '10'
            }
        ]
        },
        dataType: "json"
    });
});

It is possible to query collections by relations - just supply the relation name as fieldName and identifier as value.

1. Using an RPC created by this module for each collection on each resource: /resource/id/childresource/child_id

2. Assuming we have defined 2 entities, User and UserGroup...

/**
 * @Entity
 */
class User {
    /**
     * @ManyToOne(targetEntity="UserGroup")
     * @var UserGroup
     */
    protected $group;
}

/**
 * @Entity
 */
class UserGroup {}

... we can find all users that belong to UserGroup id #1 with the following query:

    $url = 'http://localhost:8081/api/db/entity/user';
    $query = http_build_query(array(
        array('type' => 'eq', 'field' => 'group', 'value' => '1')
    ));

You may include in the _GET[zoom] an array of field names which are collections to return instead of a link to the collection.

    /api/user_data?zoom%5B0%5D=UserGroup

When a date field is involved in a query you may specify the format of the date using PHP date formatting options. The default date format is Y-m-d H:i:s If you have a date field which is just Y-m-d then add the format to the query.

    'format' => 'Y-m-d', 
    'value' => '2014-02-04',
