Gaufrette Bundle

Provides a Gaufrette integration for your Symfony projects.

About Gaufrette

Gaufrette is a PHP 5.3+ library providing a filesystem abstraction layer. This abstraction layer permits you to develop your applications without the need to know where all their medias will be stored and how.

Documentation is available the official page of Gaufrette.

Installation

Prerequisites

As this bundle is an integration for Symfony of the Gaufrette library, it requires you to first install Gaufrette in a Symfony project.

Download the bundle

You can download an archive of the bundle and unpack it in the vendor/bundles/Knp/Bundle/GaufretteBundle directory of your application.

Standard Edition Style

If you are using the deps file to manage your project's dependencies, you must add the following lines to it:

[gaufrette]
    git=http://github.com/KnpLabs/Gaufrette.git

[KnpGaufretteBundle]
    git=http://github.com/KnpLabs/KnpGaufretteBundle.git
    target=/bundles/Knp/Bundle/GaufretteBundle

Composer Style

Bundle can be installed using composer by add to require composer.json part "knplabs/knp-gaufrette-bundle": "dev-master" line.

Git Submodule Style

If you are versioning your project with git, you had better to embed it as a submodule:

$ git submodule add https://github.com/KnpLabs/KnpGaufretteBundle.git vendor/bundles/Knp/Bundle/GaufretteBundle

Add the namespace in the autoloader

You must register both Gaufrette and the KnpGaufretteBundle in your autoloader: (You do not have to do that if you are using composer autoload system.)

<?php

// app/autoload.php

$loader->registerNamespaces(array(
    'Knp\Bundle'                => __DIR__.'/../vendor/bundles',
    'Gaufrette'                 => __DIR__.'/../vendor/gaufrette/src',
    // ...
));

Register the bundle

You must register the bundle in your kernel:

<?php

// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(

        // ...

        new Knp\Bundle\GaufretteBundle\KnpGaufretteBundle()
    );

    // ...
}

Configuration

The Gaufrette bundle allows you to declare your filesystems as services without having to reach into the famous "Service Container". Indeed, you can do it with the configuration!

The configuration of the Gaufrette bundle is divided into two parts: the adapters and the filesystems.

Configuring the Adapters

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            local:
                directory: /path/to/my/filesystem

The defined adapters are usable to create the filesystems.

Configuring the Filesystems

# app/config/config.yml
knp_gaufrette:
    adapters:
        # ...
    filesystems:
        bar:
            adapter:    foo
            alias:      foo_filesystem

Each defined filesystem must have an adapter with the key of an adapter as value. The filesystem defined above with result in a service with id gaufrette.bar_filesystem. The alias parameter permits to also defines an alias for it.

The filesystem map

You can access to all declared filesystems through the map service. In the previous exemple, we declared a bar filesystem:

$container->get('knp_gaufrette.filesystem_map')->get('bar');

Returns the instance of Gaufrette\Filesystem for bar.

Adapters Reference

Local Adapter

A simple local filesystem based adapter.

Parameters

  • directory The directory of the filesystem (required)
  • create Whether to create the directory if it does not exist (default true)

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            local:
                directory:  /path/to/my/filesystem
                create:     true

Safe Local Adapter (safe_local)

Almost as simple as the local adapter, but it encodes key to avoid having to deal with the directories structure.

Parameters

  • directory The directory of the filesystem (required)
  • create Whether to create the directory if it does not exist (default true)

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            safe_local:
                directory:  /path/to/my/filesystem
                create:     true

Service (service)

Allows you to use a user defined adapter service.

Parameters

  • id The id of the service (required)

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            service:
                id:     my.adapter.service

In Memory (in_memory)

Adapter for test purposes, it stores files in an internal array.

Parameters

  • files An array of files (optional)

The files is an array of files where each file is a sub-array having the content, checksum and mtime optional keys.

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            in_memory:
                files:
                    'file1.txt':    ~
                    'file2.txt':
                        content:    Some content
                        checksum:   abc1efg2hij3
                        mtime:      123456890123

GridFS (gridfs)

Adapter that allows you to use a MongoDB GridFS for storing files.

Parameters

  • mongogridfs_id The id of the service that provides MongoGridFS object instance for adapter (required)

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            gridfs:
                mongogridfs_id: acme_test.gridfs

In your AcmeTestBundle, add following service definitions:

# src/Acme/TestBundle/Resources/config/services.yml
parameters:
    acme_test.mongo.server: "mongodb://localhost:27017"
    acme_test.mongo.options:
        connect: true

Stream Wrapper

You can register filesystems with a specified domain. And use as a stream wrapper anywhere in your code like : gaufrette://domain/file.txt

Parameters

  • protocol The protocol name like gaufrette://… (default gaufrette)
  • filesystem An array that contains files systems that you want to register with the possibility to set the key of the array as the domain like gaufrette://mydomain/… (default all filesystems)

Example 1

The protocol is gaufrette and all filesystems will be saved

# app/config/config.yml
knp_gaufrette:
    adapters:
        backup: #...
        amazon: #...

    filesystems:
        backup1:
            adapter: backup
        amazonS3:
            adapter: amazon

    stream_wrapper: ~

gaufrette://backup1/file
gaufrette://amazonS3/file

Example 2

We define the protocol as data and all filesystem will be saved

# app/config/config.yml
knp_gaufrette:
    filesystems:
        #...

    stream_wrapper:
        protocol: data

data:///backup1/...
data://amazonS3/...

Example 3

We define the protocol as data and define which filesystem will be used

# app/config/config.yml
knp_gaufrette:
    filesystems:
        #...

    stream_wrapper:
        protocol: data
        filesystems:
            - backup1
            - amazonS3

data://backup1/...
data://amazonS3/...

Example 4

We define the protocol as data and define which filesystem will be used with the domain aliasing

# app/config/config.yml
knp_gaufrette:
    filesystems:
        #...

    stream_wrapper:
        protocol: data
        filesystems:
            backup: backup1
            pictures: amazonS3

data://backup/...
data://pictures/...
