coherence.backends.elisa_storage (module)

class ElisaMediaStore(server, **kwargs)

Bases: coherence.backend.Backend

This is a backend to the Elisa Media DB

Elisa needs to expose two methods

get_root_id(media_type)
    if media_type == '*'
        this returns the root id of the media collection
    if media_type == 'audio'
        this returns the root id of the audio collection

get_item_by_id(id)
    this returns a dict with the following keys:
    id = id in the media db
    parent_id = parent_id in the media db
    name = title, album name or basename
    mimetype = 'directory' or real mimetype
    children = list of objects for which this item is the parent
    location = filesystem path if item is a file
    cover = url by which the cover image can be retrieved  (OPTIONAL)
    size = in bytes (OPTIONAL)

Changed in version 0.9.0:

• Migrated from louie/dispatcher to EventDispatcher

• Introduced Backend’s inheritance

implements = ['MediaServer']

get_store()

get_by_id(id)

set_root_id(id)

get_root_id(media_type='audio')

ask Elisa to tell us the id of the top item representing the media_type == ‘something’ collection

upnp_init()

This method gets called after the device is fired, here all initializations of service related state variables should happen, as the services aren’t available before that point.
