Fabio Manganiello	d872835093	New API to check if a table class exists before defining it. ... - Check if it's part of the metadata through a function call rather than checking `Base.metadata` in every single module. - Make it possible to override them (mostly for doc generation logic that needs to be able to import those classes). - Make it possible to extend them.	2023-10-09 01:33:44 +02:00
Fabio Manganiello	c311987741	Removed typing.Final from some of the most commonly used modules. ... `typing.Final` is not defined on Python < 3.8.	2023-09-26 23:50:10 +02:00
Fabio Manganiello	a8255f3621	Pass the configuration file used by the application to the Alembic process. ... The database settings could also be overridden in the configuration file besides the command line. We should therefore pass the path to the runtime configuration file, so the Alembic process can initialize its configuration from the same file and use the same settings.	2023-08-19 13:23:20 +02:00
Fabio Manganiello	181da63c89	Pass the database engine to the Alembic process as an extra argument. ... If the path of the default database engine is overridden via `--workdir` option then it won't be visible to the new `python` subprocess spawned for Alembic.	2023-08-19 13:02:05 +02:00
Fabio Manganiello	2cab836bdf	Entity.columns class property replaced by Entity.get_columns method. ... Again, Python < 3.9 doesn't like the combination of `@property` + `@classmethod`.	2023-08-18 17:20:53 +02:00
Fabio Manganiello	998990aabc	Made Entity.children_ids resilient against deleted objects.	2023-05-01 22:09:16 +02:00
Fabio Manganiello	ce248ccfbb	Added children_ids to the entity attributes serialized in to_json.	2023-05-01 19:59:13 +02:00
Fabio Manganiello	78cee5d9b0	Added support for automatic database migrations. ... Added Alembic environment and `run_db_migrations` logic to the entities engine so database schema changes can be processed as soon as the application is started.	2023-04-29 11:32:31 +02:00
Fabio Manganiello	8478245cde	Removed Mapped[Entity] type annotation. ... `Mapped` has been introduced only in SQLAlchemy 1.4, while Debian stable still ships 1.3. Removing the type annotation doesn't come with a big cost, but it keeps Platypush compatible with Debian stable.	2023-04-24 21:48:52 +02:00
Fabio Manganiello	4c19535612	A more resilient logic on entity copy/serialization to prevent ObjectDeletedError	2023-04-13 17:16:21 +02:00
Fabio Manganiello	3cd42c9e45	Entity should use Message.Encoder as a JSON serializer.	2023-04-02 02:44:19 +02:00
Fabio Manganiello	9e5ad0e0b1	Entity.to_dict now takes into account columns mapped to properties. ... No more `_value` in the JSON output instead of the `value` property. If a column is marked as private, and there's an associated property mapped to its public name, then we should use and serialize that value.	2023-04-02 02:22:40 +02:00
Fabio Manganiello	b1cb7ef847	Added a list of excluded_manufacturers to BluetoothPlugin.	2023-03-21 14:32:45 +01:00
Fabio Manganiello	878fe91155	Big rewrite/refactor of the entities merger	2023-03-19 12:40:48 +01:00
Fabio Manganiello	4bc61133c5	The Entity object should also have a to_json method.	2023-03-12 23:01:51 +01:00
Fabio Manganiello	f45e47363d	Use lazy='joined' instead of lazy='selectin' on Entity.parent. ... That's the best way to ensure that all the columns are fetched eagerly and prevent errors later when trying to access lazily loaded attributes outside of the session/thread.	2023-03-10 12:01:23 +01:00
Fabio Manganiello	7e92d5f244	Added recursive .copy() method to Entity.	2023-03-09 22:35:31 +01:00
Fabio Manganiello	9f9ee575f1	Added _import_error_ignored_modules. ... ImportErrors on these entity modules will be ignored when dynamically loading them, since they have optional external dependencies and we shouldn't throw an error if we can't import them.	2023-03-09 01:40:35 +01:00
Fabio Manganiello	c4efec6832	Several fixes and improvements on the entities engine. ... - Support for an optional callback on `publish_entities` to get notified when the published object are flushed to the db. - Use `lazy='selectin'` for the entity parent -> children relationship - it is more efficient and it ensures that all the data the application needs is loaded upfront. - `Entity.entity_key` rolled back to `<external_id, plugin>`. The fallback logic on `<id, plugin>` created more problems than those it as supposed to solve. - Added `expire_on_commit=False` to the entities engine session to make sure that we don't get errors on detached/expired instances.	2023-03-09 01:16:04 +01:00

Fabio Manganiello	1c811a490f	Don't serialize children_ids in Entity.to_json() ... Serializing both children_ids and parent_id can result in nasty SQLAlchemy bugs, especially when handling objects that haven't been flushed yet.	2023-01-01 12:47:15 +01:00

Fabio Manganiello	86edd70d93	Fixed session/concurrency management on the main SQLite db ... - The `declarative_base` instance should be shared - Database `session_locks` should be stored at module, not instance level - Better isolation of scoped sessions - Enclapsulated `get_session` method in `UserManager`	2022-11-12 15:36:17 +01:00
Fabio Manganiello	6b7933cd33	Using a different SQLite database for entities ... This prevents multiprocessing/concurrency issues when modifying the same database file both from the main process and from the web server process	2022-11-12 02:00:55 +01:00

Fabio Manganiello	947b50b937	Added meta as a JSON field on the Entity table ... Metadata attributes can now be defined and overridden on the object itself, as well as on the database. Note that db settings will always take priority in case of value conflicts.	2022-04-07 22:11:31 +02:00
Fabio Manganiello	db7c2095ea	Implemented meta property for entities (for now it only include icon_class)	2022-04-07 18:09:25 +02:00
