API Documentation
|
|
=================
|
|
|
|
.. currentmodule:: beets.library
|
|
|
|
This page describes the internal API of beets' core. It's a work in
|
|
progress---since beets is an application first and a library second, its API
|
|
has been mainly undocumented until recently. Please file bugs if you run
|
|
across incomplete or incorrect docs here.
|
|
|
|
The :class:`Library` object is the central repository for data in beets. It
|
|
represents a database containing songs, which are :class:`Item` instances, and
|
|
groups of items, which are :class:`Album` instances.

The Library Class
|
|
-----------------
|
|
|
|
.. autoclass:: Library(path, directory[, path_formats[, replacements]])
|
|
|
|
.. automethod:: items
|
|
|
|
.. automethod:: albums
|
|
|
|
.. automethod:: get_item
|
|
|
|
.. automethod:: get_album
|
|
|
|
.. automethod:: add
|
|
|
|
.. automethod:: add_album
|

|
|
.. automethod:: transaction

Transactions
|
|
''''''''''''
|
|
|
|
The :class:`Library` class provides the basic methods necessary to access and
|
|
manipulate its contents. To perform more complicated operations atomically, or
|
|
to interact directly with the underlying SQLite database, you must use a
|
|
*transaction*. For example::
|
|
|
|
lib = Library()
|
|
with lib.transaction() as tx:
|
|
items = lib.items(query)
|
|
lib.add_album(list(items))
|
|
|
|
.. autoclass:: Transaction

Model Classes
|
|
-------------
|
|
|
|
The two model entities in beets libraries, :class:`Item` and :class:`Album`,
|
|
share base classes that provide generic data storage. The :class:`LibModel`
|
|
class inherits from :class:`FlexModel`, and both :class:`Item` and
|
|
:class:`Album` inherit from it.
|
|
|
|
The fields model classes can be accessed using attributes (dots, as in
|
|
``item.artist``) or items (brackets, as in ``item['artist']``). The
|
|
:class:`FlexModel` base class provides some methods that resemble `dict`
|
|
objects.
