class Base[source]

Bases: AsyncAttrs, DeclarativeBase

A simple constructor that allows initialization from kwargs.

Sets attributes on the constructed instance using the names and values in kwargs.

Only keys that are present as attributes of the instance’s class are allowed. These could be, for example, any mapped columns or relationships.

__init__(**kwargs)

A simple constructor that allows initialization from kwargs.

Sets attributes on the constructed instance using the names and values in kwargs.

Only keys that are present as attributes of the instance’s class are allowed. These could be, for example, any mapped columns or relationships.

Parameters:
Return type:

None

metadata: ClassVar[MetaData] = MetaData()

Refers to the _schema.MetaData collection that will be used for new _schema.Table objects.

orm_declarative_metadata

registry: ClassVar[_RegistryType] = <sqlalchemy.orm.decl_api.registry object>

Refers to the _orm.registry in use where new _orm.Mapper objects will be associated.

class Blob[source]

Bases: Base

A simple constructor that allows initialization from kwargs.

Sets attributes on the constructed instance using the names and values in kwargs.

Only keys that are present as attributes of the instance’s class are allowed. These could be, for example, any mapped columns or relationships.

__init__(**kwargs)

class BlobsRepository[source]

Bases: Repository[Blob]

Type

alias of Blob

count_orphans()[source]
async create(values, /, *, session)[source]
Parameters:

values (dict | Blob)

delete_orphans()[source]
select_orphans()[source]

The ids delete_orphans would remove.

Deleting blobs with a bulk statement leaves anything caching their existence, such as SqlBlobStorage.seen, believing rows are there that are not. The caller needs to know which ids went, so the count, the selection and the deletion all read from one definition of “orphan” and cannot drift apart.

class FlagsRepository[source]

Bases: Repository

Type

alias of UserFlag
