class trilium_alchemy.core.entity.EntityIdDescriptor

Accessor for read-only entity id.

Raises:

ReadOnlyError – Upon write attempt

class trilium_alchemy.core.entity.FieldDescriptor(field: str)

When written, updates the working state which will be committed to Trilium upon flush. When read, returns the working state if set by user, or the state from Trilium if not.

class trilium_alchemy.core.entity.ReadOnlyFieldDescriptor(field: str)

Bases:

trilium_alchemy.core.entity.FieldDescriptor

Accessor for a read-only model field, e.g. a Note’s date_created field.

Raises:

ReadOnlyError – Upon write attempt

class trilium_alchemy.core.entity.ReadOnlyDescriptor(attr: str, allow_none_cb: str | None = None, allow_none: bool = False)

Accessor for read-only class attribute.

Raises:

ReadOnlyError – Upon write attempt

class trilium_alchemy.core.entity.WriteThroughDescriptor(attr: str, attr_attr: str, field: str)

Accessor for class attribute which immediately populates the underlying model field when updated.

class trilium_alchemy.core.entity.WriteOnceDescriptor(attr: str, validator: Callable = None)

Accessor for field which is only allowed a single value. Subsequent assignments are a no-op if they set the same value.

Raises:
