Apigility for Doctrine

This module provides the classes for integrating Doctrine with Apigility.

Installation

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

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

This library provides two modules. The first, ZF\Apigility\Doctrine\Server provides the classes to serve data created by the second, ZF\Apigility\Doctrine\Admin. The Admin module is used to create apigility resources and the Server serves those created resoruces. Generally you would include Admin in your development.config.php and Server in your application.config.php

API Resources

/apigility/api/doctrine[/:object_manager_alias]/metadata[/:name]

This will return metadata for the named entity which is a member of the named object manager. Querying without a name will return all metadata for the object manager.

/apigility/api/module[/:name]/doctrine[/:controller_service_name]

This is a Doctrine resource creation route like Apigility Rest /apigility/api/module[/:name]/rest[/:controller_service_name] POST Parameters:

{
    "objectManager": "doctrine.entitymanager.orm_default",
    "resourceName": "Artist",
    "entityClass": "Db\\Entity\\Artist",
    "routeIdentifierName": "artist_id",
    "entityIdentifierName": "id",
    "routeMatch": "/api/artist",
    "pageSizeParam": "limit", // optional default null
    "hydratorName": "DbApi\\V1\\Rest\\Artist\\ArtistHydrator", // Optional default generated
    "hydrateByValue": true // Optional default true
}

Hydrating Entities by Value or Reference

By default the admin tool hydrates entities by reference by setting $config['doctrine-hydrator']['hydrator_class']['by_value'] to false.

Collections

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

Reserved GET variables

    orderBy
    query

Sorting Collections

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

Querying Collections

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': 'or',
                'type': 'between',
                'from': '1',
                'to': '100'
            },
            {
                'field': 'cycle',
                'where': 'or',
                'type': 'gte',
                'value': '1000'
            }
        ]
        },
        dataType: "json"
    });
});

Querying Relations

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

Using an RPC created by this module for each collection on each resource: /resource/id/childresource/child_id
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/user';
    $query = http_build_query(array(
        array('type' => 'eq', 'field' => 'group', 'value' => '1')
    ));

Format of Date Fields

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',

Available Query Types

ORM and ODM

Equals

    array('type' => 'eq', 'field' => 'fieldName', 'value' => 'matchValue')

Not Equals

    array('type' => 'neq', 'field' => 'fieldName', 'value' => 'matchValue')

Less Than

    array('type' => 'lt', 'field' => 'fieldName', 'value' => 'matchValue')

Less Than or Equals

    array('type' => 'lte', 'field' => 'fieldName', 'value' => 'matchValue')

Greater Than

    array('type' => 'gt', 'field' => 'fieldName', 'value' => 'matchValue')

Greater Than or Equals

    array('type' => 'gte', 'field' => 'fieldName', 'value' => 'matchValue')

Is Null

    array('type' => 'isnull', 'field' => 'fieldName')

Is Not Null

    array('type' => 'isnotnull', 'field' => 'fieldName')

Dates in the In and NotIn filters are not handled as dates. It is recommended you use multiple Equals statements instead of these filters.

    array('type' => 'in', 'field' => 'fieldName', 'values' => array(1, 2, 3))

NotIn

    array('type' => 'notin', 'field' => 'fieldName', 'values' => array(1, 2, 3))

Between

    array('type' => 'between', 'field' => 'fieldName', 'from' => 'startValue', 'to' => 'endValue')

Like (% is used as a wildcard)

    array('type' => 'like', 'field' => 'fieldName', 'value' => 'like%search')

ODM Only

Regex

    array('type' => 'regex', 'field' => 'fieldName', 'value' => '/.*search.*/i')
