Gaufrette Bundle
================
Provides a [Gaufrette][gaufrette-homepage] 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][gaufrette-homepage].
Installation
------------
## Prerequisites
As this bundle is an integration for Symfony of the [Gaufrette][gaufrette-homepage] library, it requires you to first install [Gaufrette][gaufrette-homepage] 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
<?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
<?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
``` yaml
# 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
``` yaml
# 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:
``` php
$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
``` yaml
# 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
``` yaml
# 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
``` yaml
# 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
``` yaml
# 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](http://www.windowsazure.com/en-us/develop/php/common-tasks/download-php-sdk/) 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:
``` yaml
# 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](https://manage.windowsazure.com).
### 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
``` yaml
# 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
``` yaml
# app/config/config.yml
knp_gaufrette:
adapters:
foo:
gridfs:
mongogridfs_id: acme_test.gridfs
```
In your AcmeTestBundle, add following service definitions:
``` yaml
# src/Acme/TestBundle/Resources/config/services.yml
parameters:
acme_test.mongo.server: "mongodb://localhost:27017"
acme_test.mongo.options:

## 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"
},
```
Note that Gaufrette is not currently compatible with the v2 Amazon SDK (called "aws/aws-sdk-php").
### 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:
``` yaml
# 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:
``` yaml
# 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.
## 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:
``` yaml
# 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:
``` yaml
# 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:
``` yaml
# 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:
``` yaml
# 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:
``` yaml
# 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:
``` yaml
# 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
``` yaml
# 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
``` yaml
# 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)
``` yaml
# 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
``` yaml
# 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
``` yaml
# app/config/config.yml
knp_gaufrette:
filesystems:
#...
stream_wrapper:
protocol: data
filesystems:
backup: backup1
pictures: amazonS3
```
```
data://backup/...
data://pictures/...
```
