New in version 1.0.
Create a new playlist.
If uri_scheme matches an URI scheme handled by a current backend, that backend is asked to create the playlist. If uri_scheme is None or doesn’t match a current backend, the first backend is asked to create the playlist.
All new playlists must be created by calling this method, and not by creating new instances of mopidy.models.Playlist.
Parameters: |
|
---|---|
Return type: |
Delete playlist identified by the URI.
If the URI doesn’t match the URI schemes handled by the current backends, nothing happens.
Parameters: | uri (string) – URI of the playlist to delete |
---|
Filter playlists by the given criterias.
Examples:
# Returns track with name 'a'
filter({'name': 'a'})
filter(name='a')
# Returns track with URI 'xyz'
filter({'uri': 'xyz'})
filter(uri='xyz')
# Returns track with name 'a' and URI 'xyz'
filter({'name': 'a', 'uri': 'xyz'})

Parameters: | criteria (dict) – one or more criteria to match by |
---|---|
Return type: | list of mopidy.models.Playlist |
Deprecated since version 1.0: Use as_list() and filter yourself.

Changed in version 1.0: If you call the method with include_tracks=False, the last_modified field of the returned playlists is no longer set.
Deprecated since version 1.0: Use as_list() and get_items() instead.
Lookup playlist with given URI in both the set of playlists and in any other playlist sources. Returns None if not found.
Parameters: | uri (string) – playlist URI |
---|---|
Return type: | mopidy.models.Playlist or None |
Deprecated since version 1.0: Use as_list() and get_items() instead.
Refresh the playlists in playlists.
If uri_scheme is None, all backends are asked to refresh. If uri_scheme is an URI scheme handled by a backend, only that backend is asked to refresh. If uri_scheme doesn’t match any current backend, nothing happens.
Parameters: | uri_scheme (string) – limit to the backend matching the URI scheme |
---|
Save the playlist.
For a playlist to be saveable, it must have the uri attribute set. You must not set the uri atribute yourself, but use playlist objects returned by create() or retrieved from playlists, which will always give you saveable playlists.
The method returns the saved playlist. The return playlist may differ from the saved playlist. E.g. if the playlist name was changed, the returned playlist may have a different URI. The caller of this method must throw away the playlist sent to this method, and use the returned playlist instead.
If the playlist’s URI isn’t set or doesn’t match the URI scheme of a current backend, nothing is done and None is returned.
Parameters: | playlist (mopidy.models.Playlist) – the playlist |
---|---|
Return type: | mopidy.models.Playlist or None |
Manages the music library, e.g. searching for tracks to be added to a playlist.
Browse directories and tracks at the given uri.
uri is a string which represents some directory belonging to a backend. To get the intial root directories for backends pass None as the URI.
Returns a list of mopidy.models.Ref objects for the directories and tracks at the given uri.
The Ref objects representing tracks keep the track’s original URI. A matching pair of objects can look like this:
Track(uri='dummy:/foo.mp3', name='foo', artists=..., album=...)
Ref.track(uri='dummy:/foo.mp3', name='foo')
The Ref objects representing directories have backend specific URIs. These are opaque values, so no one but the backend that created them should try and derive any meaning from them. The only valid exception to this is checking the scheme, as it is used to route browse requests to the correct backend.
For example, the dummy library’s /bar directory could be returned like this:
Ref.directory(uri='dummy:directory:/bar', name='bar')
Parameters: | uri (string) – URI to browse |
---|---|
Return type: | list of mopidy.models.Ref |
New in version 0.18.
Search the library for tracks where field is values.
Deprecated since version 1.0: Use search() with exact set.
List distinct values for a given field from the library.
This has mainly been added to support the list commands the MPD protocol supports in a more sane fashion. Other frontends are not recommended to use this method.
Parameters: |
|
---|---|
Return type: | set of values corresponding to the requested field type. |
New in version 1.0.
Lookup the images for the given URIs
Backends can use this to return image URIs for any URI they know about be it tracks, albums, playlists... The lookup result is a dictionary mapping the provided URIs to lists of images.
Unknown URIs or URIs the corresponding backend couldn’t find anything for will simply return an empty list for that URI.
Parameters: | uris (list) – list of URIs to find images for |
---|---|
Return type: | {uri: tuple of mopidy.models.Image} |
New in version 1.0.
Lookup the given URI.
If the URI expands to multiple tracks, the returned list will contain them all.
Parameters: |
|
---|---|
Return type: | list of mopidy.models.Track if uri was set or a {uri: list of mopidy.models.Track} if uris was set. |
New in version 1.0: The uris argument.
Deprecated since version 1.0: The uri argument. Use uris instead.
Refresh library. Limit to URI and below if an URI is given.
Parameters: | uri (string) – directory or track URI |
---|
Search the library for tracks where field contains values.
Deprecated since version 1.0: Previously, if the query was empty, and the backend could support it, all available tracks were returned. This has not changed, but it is strongly discouraged. No new code should rely on this behavior.
If uris is given, the search is limited to results from within the URI roots. For example passing uris=['file:'] will limit the search to the local backend.
Examples:
# Returns results matching 'a' in any backend
search({'any': ['a']})
search(any=['a'])
# Returns results matching artist 'xyz' in any backend
search({'artist': ['xyz']})
search(artist=['xyz'])
# Returns results matching 'a' and 'b' and artist 'xyz' in any
# backend
search({'any': ['a', 'b'], 'artist': ['xyz']})
search(any=['a', 'b'], artist=['xyz'])
# Returns results matching 'a' if within the given URI roots
# "file:///media/music" and "spotify:"
search({'any': ['a']}, uris=['file:///media/music', 'spotify:'])
search(any=['a'], uris=['file:///media/music', 'spotify:'])
Parameters: |
|
---|---|
Return type: | list of mopidy.models.SearchResult |

Marker interface for recipients of events sent by the core actor.
