README

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 allows you to develop applications without needing to know where all their media files will be stored or 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

This bundle can be installed using composer by adding the following in the require section of your composer.json file:

    "require": {
        ...
        "knplabs/knp-gaufrette-bundle": "dev-master"
    },

Git Submodule Style

If you are versioning your project with git and making changes to this bundle you can 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 this if you are using the composer autoload system.)

<?php

// app/autoload.php

$loader->addClassMap(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 then used 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 its value set to an adapter's key. The filesystem defined above will result in a service with id gaufrette.bar_filesystem. The alias parameter allows us to define an alias for it (foo_filesystem in this case).

The filesystem map

You can access 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 bar instance of Gaufrette\Filesystem.

Adapters Reference

Local Adapter (local)

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

Azure Blob Storage (azure_blob_storage)

Adapter for Microsoft Azure Blob Storage service. To use this adapter you need to install the Azure SDK for php into your project.

Further more you need a valid connection string and you must define a Blob Proxy factory service with it. You can use the default \Gaufrette\Adapter\AzureBlobStorage\BlobProxyFactory this way:

# app/config/config.yml
services:
    azure_blob_proxy_factory:
        class: Gaufrette\Adapter\AzureBlobStorage\BlobProxyFactory
        arguments: [%azure_blob_storage_connection_string%]

You must set the parameter azure_blob_storage_connection_string to contain your windows azure blob storage connection string. You can retrieve your connection string in your Windows Azure management console.

Parameters

blob_proxy_factory_id Reference to the blob proxy factory service
container_name The name of the container
create_container Boolean value that indicates whether to create the container if it does not exists (optional: default false)
detect_content_type Boolean value that indicates whether to auto determinate and set the content type on new blobs (optional: default true)

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            azure_blob_storage:
                blob_proxy_factory_id: azure_blob_proxy_factory
                container_name: my_container
                create_container: true

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

A non-persistent adapter, use it in the dev environment, in demo sites, ...

Parameters

prefix The prefix to this filesystem (APC 'namespace', it is recommended that this end in a dot '.') (required)
ttl Time to live (default 0)

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            apc:
                prefix: APC 'namespace' prefix
                ttl: 0

Amazon S3 (amazon_s3)

Adapter to connect to Amazon S3 instances.

This adapter requires the use of amazonwebservices/aws-sdk-for-php which can be installed by adding the following line to your composer.json:

    "require": {
        ...
        "amazonwebservices/aws-sdk-for-php": "1.6.2"
    },

Parameters

amazon_s3_id: the id of the AmazonS3 service used for the underlying connection
bucket_name: the name of the bucket to use
options: additional (optional) settings
- directory: the directory to use, within the specified bucket
- region
- create

Defining services

To use the Amazon S3 adapter you need to provide a valid AmazonS3 instance (as defined in the Amazon SDK). This can easily be set up as using Symfony's service configuration:

# app/config/config.yml
services:
    amazonS3:
        class: AmazonS3
        arguments:
            options:
                key:      '%aws_key%'
                secret:   '%aws_secret_key%'

Example

Once the service is set up use its key as the amazon_s3_id in the gaufrette configuration:

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            amazon_s3:
                amazon_s3_id:   amazonS3
                bucket_name:    foo_bucket
                options:
                    directory:  foo_directory

Note that the SDK seems to have some issues with bucket names with dots in them, e.g. "com.mycompany.bucket" seems to have issues but "com-mycompany-bucket" works.

AwsS3

Adapter for Amazon S3 SDK v2.

Parameters

service_id The service id of the Aws\S3\S3Client to use. (required)
bucket_name The name of the S3 bucket to use. (required)
options A list of additional options passed to the adapter.
- create Whether to create the bucket if it doesn't exist. (default false)
- directory A directory to operate in. (default '') This directory will be created in the root of the bucket and all files will be read and written there.

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        profile_photos:
            aws_s3:
                service_id: 'acme.aws_s3.client'
                bucket_name: 'images'
                options:
                    directory: 'profile_photos'

Open Cloud (opencloud)

Adapter for OpenCloud (Rackspace)

Parameters

object_store_id: the id of the object store service
container_name: the name of the container to use
create_container: if true will create the container if it doesn't exist (default false)
detect_content_type: if true will detect the content type for each file (default true)

Defining services

To use the OpenCloud adapter you should provide a valid ObjectStore instance. You can retrieve an instance through the OpenCloud\OpenStack or OpenCloud\Rackspace instances. We can provide a comprehensive configuration through the Symfony DIC configuration.

Define OpenStack/Rackspace service

Generic OpenStack:

# app/config/config.yml
services:
    opencloud.connection:
        class: OpenCloud\OpenStack
        arguments:
          - %openstack_identity_url%
          - {username: %openstack_username%, password: %openstack_password%, tenantName: %openstack_tenant_name%}

HPCloud:

# app/config/config.yml
services:
    opencloud.connection.hpcloud:
        class: OpenCloud\OpenStack
        arguments:
          - 'https://region-a.geo-1.identity.hpcloudsvc.com:123456/v2.0/' // check https://account.hpcloud.com/account/api_keys for identities urls
          - {username: %hpcloud_username%, password: %hpcloud_password%, tenantName: %hpcloud_tenant_name%}

The username and password are your login credentials, not the api key. Your tenantName is your Project Name on the api keys page.

Rackspace:

# app/config/config.yml
services:
    opencloud.connection.rackspace:
        class: OpenCloud\Rackspace
        arguments:
          - 'https://identity.api.rackspacecloud.com/v2.0/'
          - {username: %rackspace_username%, apiKey: %rackspace_apikey%}

Define ObjectStore service

HPCloud:

# app/config/config.yml
services:
    opencloud.object_store:
        class: OpenCloud\ObjectStoreBase
        factory_service: opencloud.connection.hpcloud
        factory_method: ObjectStore
        arguments:
          - 'Object Storage' # Object storage type
          - 'region-a.geo-1' # Object storage region
          - 'publicURL' # url type

Rackspace:

# app/config/config.yml
services:
    opencloud.object_store:
        class: OpenCloud\ObjectStoreBase
        factory_service: opencloud.connection
        factory_method: ObjectStore
        arguments:
          - 'cloudFiles' # Object storage type
          - 'DFW' # Object storage region
          - 'publicURL' # url type

Example

Finally you can define your adapter in configuration:

# app/config/config.yml
knp_gaufrette:
    adapters:
        foo:
            opencloud:
                object_store_id: opencloud.object_store
                container_name: foo

Cache (cache)

Adapter which allows you to cache other adapters

Parameters

source The source adapter that must be cached (required)
cache The adapter used to cache the source (required)
ttl Time to live (default 0)
serializer The adapter used to cache serializations (default null)

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        media_ftp:
            ftp:
                host: example.com
                username: user
                password: pass
                directory: /example/ftp
                create: true
                mode: FTP_BINARY
        media_apc:
            apc:
                prefix: APC 'namespace' prefix
                ttl: 0
        media_cache:
            cache:
                source: media_ftp
                cache: media_apc
                ttl: 7200
    filesystems:
        media:
            adapter: media_cache

Stream Wrapper

The stream_wrapper settings allow you to register filesystems with a specified domain and then 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 filesystems that you want to register to this stream_wrapper. If you set array keys these will be used as an alias for the filesystem (see examples below) (default all filesystems without aliases)

Example 1

Using default settings, the protocol is "gaufrette" and all filesystems will be served

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

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

    stream_wrapper: ~

gaufrette://backup1/...
gaufrette://amazonS3/...

Example 2

We define the protocol as "data", all filesystem will still be served (by default)

# 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(s) will be available

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

    stream_wrapper:
        protocol: data
        filesystems:
            - backup1

data://backup1/... (works since it is defined above)
data://amazonS3/... (will not be available)

Example 4

We define the protocol as data and define which filesystems will be available using array keys to set domain aliases

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

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

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

Doctrine DBAL (doctrine_dbal)

Adapter that allows you to store data into a database.

Parameters

connection_name The doctrine dbal connection name like default
table The table name like media_data
key: The primary key in the table
content: The field name of the file content
mtime: The field name of the timestamp
checksum: The field name of the checksum

Example

# app/config/config.yml
knp_gaufrette:
    adapters:
        database:
            doctrine_dbal:
                connection_name: default

                columns:
                    key: id
                    content: text
                    mtime: date
