Usage

Basic Operations

Covering the basic CRUD Operations for databases and documents:

1 <?php

declare(strict_types=1);

use Doctrine\CouchDB\CouchDBClient;
use Doctrine\CouchDB\Mango\MangoQuery;
use Doctrine\CouchDB\View\DesignDocument;

$client = CouchDBClient::create(['dbname' => 'doctrine_example']);

// Create a database.
$client->createDatabase($client->getDatabase());

// Create a new document.
list($id, $rev) = $client->postDocument(['foo' => 'bar']);

// Update a existing document. This will increment the revision.
list($id, $rev) = $client->putDocument(['foo' => 'baz'], $id, $rev);

// Fetch single document by id.
$doc = $client->findDocument($id);

// Fetch multiple documents at once.
$docs = $client->findDocuments([$id]);

// Return all documents from database (_all_docs?include_docs=true).
$allDocs = $client->allDocs();

// Delete a single document.
$client->deleteDocument($id, $rev);

// Delete a database.
$client->deleteDatabase($client->getDatabase());

// Search documents using Mango Query CouchDB v2.x

$selector = ['_id' => ['$gt' => null]];
$options  = ['limit' => 1,'skip' => 1,'use_index' => ['_design/doc','index'],'sort' => [['_id' => 'desc']]];
$query    = new MangoQuery($selector, $options);
$docs     = $client->find($query);

$query = new MangoQuery();
$query->select(['_id', 'name'])->where(['$and'=> [
  [
    'name'=> ['$eq' => 'Under the Dome'],
    'genres'=> [
      '$in'=> ['Drama','Comedy'],
    ],
  ],
])
->sort([['_id' => 'desc']])
->limit(1)
->skip(1)
->use_index(['_design/doc', 'index']);

$docs = $client->find($query);

Views

A simple example demonstrating how to create views and query them:

1 class ArticlesDesignDocument implements DesignDocument
{
    public function getData()
    {
        return [
            'language' => 'javascript',
            'views' => [
                'by_author' => [
                    'map' => "function(doc) {
                        if('article' == doc.type) {
                            emit(doc.author, doc._id);
                        }
                    }",
                    'reduce' => '_count',
                ],
            ],
        ];
    }
}

$client->createDesignDocument('articles', new ArticlesDesignDocument());

// Fill database with some data.
foreach (['Alice', 'Bob', 'Bob'] as $author) {
    $client->postDocument([
        'type' => 'article',
        'author' => $author,
        'content' => 'Lorem ipsum',
    ]);
}

// Query all articles.
$query = $client->createViewQuery('articles', 'by_author');
$query->setReduce(false);
$query->setIncludeDocs(true);
$result = $query->execute();
foreach ($result as $row) {
    $doc = $row['doc'];
    echo 'Article by ', $doc['author'], ': ', $doc['content'], "\n";
}

// Article by Alice: Lorem ipsum
// Article by Bob: Lorem ipsum
// Article by Bob: Lorem ipsum

// Query all articles written by bob.
$query = $client->createViewQuery('articles', 'by_author');
$query->setKey('Bob');
// ...


// Query the _count of articles each author has written.
$query = $client->createViewQuery('articles', 'by_author');
$query->setReduce(true);
$query->setGroupLevel(1); // group_level=1 means grouping by author.
$result = $query->execute();
foreach ($result as $row) {
    echo 'Author ', $row['key'], ' has written ', $row['value'], ' articles', "\n";
}

// Author Alice has written 1 articles
// Author Bob has written 2 articles
