ATManagedFile store files on the file system while keeping a content representation in Plone.
ATManagedFile allows you to store metadata in the database
while
keeping File assets on the servers file system. Content is
treated like a first-class citizen in Plone, it can be transitioned
(workflow),
edited, copy/pasted. Metadata for content can be described
through Archetype schema's. A managed_files
tool enables
administrators to specify where content is stored, the deletion policy,
as well as the stored filesystem naming convention.
Included in ATManagedFile Pack are:
- ATManagedFile - a Archetypes extension of
CMFManagedFile. That provides the schema support.
Also has
a very thin storage layer that delegates to CMFManagedFile.
- ATMFExample - an example content definition based on
ATManagedFile.
- CMFManagedFile - a pure CMF implementation of ExternalFile
that uses the managed_files tool. Exposes
ExternalFile's methods
as well as provides CMF implementation of the capabilities.
Uses
CMF tools to define customizable policies for a site.
- ExternalFile - AerialPartners implementation of a database
-> file system content type. This provides most of the
file system manipulation functionality. It has been enhanced
to
use newer ZPublisher functionality to efficiently serve content from
the file system instead of reading the contents into memory.
In addition Archetypes 1.3.1 or greater is required.
It is
recommended to use with DAVPack to ensure large files that are uploaded
using DAV or FTP are not loaded into memory.
Functionality:
- Many tests. Using the latest ZopeTestCase and FunctionalDocTestSuite which provides developers a "read as it tests" script that documents how the API is used.
- Uses filestream_iterators to efficiently server content from the file system
- portal_managed_files provides a mechanism to extend behavior for all content that uses the ManagedFile strategy. Such as when files from the file system will be deleted.
- Have more than one Plone content item pointing to the same file on the file system.
- Works over FTP and DAV (tested with Plone Desktop)
