spinedb_api.db_mapping

This module defines the DatabaseMapping class, the main mean to communicate with a Spine DB. If you’re planning to use this class, it is probably a good idea to first familiarize yourself a little bit with the DB mapping schema.

Classes

DatabaseMapping

Enables communication with a Spine DB.

Module Contents

class spinedb_api.db_mapping.DatabaseMapping(db_url, username=None, upgrade=False, backup_url='', create=False, apply_filters=True, memory=False, commit_lock=None, sqlite_timeout=1800)

Bases: spinedb_api.db_mapping_query_mixin.DatabaseMappingQueryMixin, spinedb_api.db_mapping_commit_mixin.DatabaseMappingCommitMixin, spinedb_api.db_mapping_base.DatabaseMappingBase

Enables communication with a Spine DB.

The DB is incrementally mapped into memory as data is requested/modified, following the DB mapping schema.

Data is typically retrieved using item() or find(). If the requested data is already in memory, it is returned from there; otherwise it is fetched from the DB, stored in memory, and then returned. In other words, the data is fetched from the DB exactly once.

For convenience, we also provide specialized getter methods for each item type, e.g., entity() and find_entities().

Data is added via add(); updated via update(); removed via remove(); and restored via restore(). add_or_update() adds an item or updates an existing one. All the above methods modify the in-memory mapping (not the DB itself). These methods also fetch data from the DB into the in-memory mapping to perform the necessary integrity checks (unique and foreign key constraints).

For convenience, we also provide specialized ‘add’, ‘update’, ‘remove’, and ‘restore’ methods for each item type, e.g., add_entity(), update_entity(), remove_entity() and restore_entity().

Modifications to the in-memory mapping are committed (written) to the DB via commit_session(), or rolled back (discarded) via rollback_session().

The DB fetch status is reset via refresh_session(). This allows new items in the DB (added by other clients in the meantime) to be retrieved as well.

You can also control the fetching process via fetch_more() and/or fetch_all(). For example, you can call fetch_more() in a dedicated thread while you do some work on the main thread. This will nicely place items in the in-memory mapping, so you can access them later, without the overhead of fetching them from the DB.

The query() method is also provided as an alternative way to retrieve data from the DB while bypassing the in-memory mapping entirely.

You usually use this class as a context manager, e.g.:

with DatabaseMapping(db_url) as db_map:
    # Do stuff with db_map
    ...

or:

db_map = DatabaseMapping(db_url)
...
with db_map:
    # Do stuff with db_map
    ...

Parameters:

• db_url (str or URL) – A URL in RFC-1738 format pointing to the database to be mapped, or to a DB server.

• username (str, optional) – A user name. If not given, it gets replaced by the string anon.

• upgrade (bool, optional) – Whether the DB at the given url should be upgraded to the most recent version.

• backup_url (str, optional) – A URL to backup the DB before upgrading.

• create (bool, optional) – Whether to create a new Spine DB at the given url if it’s not already one.

• apply_filters (bool, optional) – Whether to apply filters in the url’s query segment.

• commit_lock (threading.Lock, optional) – If given, committing to the DB is done with the lock.

• memory (bool, optional) – Whether to use a SQLite memory DB as replacement for the original one.

• sqlite_timeout (int, optional) – The number of seconds to wait before raising SQLite connection errors.

query(*entities, **kwargs) → sqlalchemy.orm.Query

Returns a Query object to execute against the mapped DB.

To perform custom SELECT statements, call this method with one or more of the documented subquery properties of DatabaseMappingQueryMixin returning Subquery objetcs. For example, to select the entity class with id equal to 1:

from spinedb_api import DatabaseMapping
url = 'sqlite:///spine.db'
...
with DatabaseMapping(url) as db_map:
    entity_record = db_map.query(db_map.entity_class_sq).filter_by(id=1).one_or_none()
    if entity_record is not None:
        ...

To perform more complex queries, use SQLAlchemy’s Query interface. For example, to select all entity class names and the names of their entities concatenated in a comma-separated string:

from sqlalchemy import func

with DatabaseMapping(ur) as db_map:
    classes = db_map.query(
        db_map.entity_class_sq.c.name,
        func.group_concat(db_map.entity_sq.c.name).label("entities")
    ).filter(
        db_map.entity_sq.c.class_id == db_map.entity_class_sq.c.id
    ).group_by(
        db_map.entity_class_sq.c.name
    ).all()
