Note to use as subclass for declarative notes, i.e. note classes which automatically sync with the corresponding note if it already exists in Trilium.

Note

Subclassing this class means the note will replace any existing fields (title, type, mime, content) as well as attributes and children. Set leaf = True to preserve children.

Todo

Add auto_mime=True to also set mime using magic package (or do so automatically if BaseDeclarativeNote.content_file set, but BaseDeclarativeNote.mime_ not set)

note_id_: str | None¶

None

note_id to explicitly assign.

title_: str | None¶

None

Title to set, or None to use class name.

note_type_: str | None¶

None

Note type to set.

mime_: str | None¶

None

MIME type to set.

content_: str | bytes | IO | None¶

None

Content to set.

content_file: str | None¶

None

Name of file to use as content, relative to module’s location. Also adds #originalFilename label.

Note

Currently Trilium only shows #originalFilename if the note’s type is file.

note_id_seed: str | None¶

None

Seed from which to generate note_id. Useful to generate a collision-avoidant id from a human-friendly identifier. Generated as base64-encoded hash of seed.

note_id_segment: str | None¶

None

Segment with which to generate note_id given the parent’s note_id, if no note_id is otherwise specified.

singleton: bool¶

False

If set on a BaseDeclarativeNote subclass, enables deterministic calculation of note_id based on the fully qualified class name. This means the same class will always have the same note_id when instantiated.

Warning

If you move this class to a different module, it will result in a different note_id which will break any non-declarative relations to it. To enable more portable behavior, set BaseDeclarativeNote.idempotent or assign BaseDeclarativeNote.note_id_seed explicitly.

idempotent: bool¶

False

If set on a BaseDeclarativeNote subclass, enables deterministic calculation of note_id based on the class name. Similar to BaseDeclarativeNote.singleton, but only the class name (not fully qualified) is used.

idempotent_segment: bool¶

False

If set on a BaseDeclarativeNote subclass, sets segment name to class name for the purpose of note_id calculation. An explicitly provided BaseDeclarativeNote.note_id_segment takes precedence.

leaf: bool¶

False

If set to True on a BaseDeclarativeNote subclass, disables setting of child notes declaratively, allowing children to be manually maintained by the user. Otherwise, notes added by the user will be deleted to match the children added declaratively.

Should be set on notes intended to hold user notes, e.g. todo lists.

hide_new_note: bool¶

False

Whether to hide “new note” button, regardless of whether it would otherwise be hidden. Can be used to hide “new note” button for e.g. Templates which otherwise would show it.

init(attributes: list[BaseAttribute], children: list[Branch])¶

Inherited from: trilium_alchemy.core.declarative.base.BaseDeclarativeMixin

Can be overridden to add attributes and/or children during instantiation. Use the following to create attribute/child with deterministic id:

BaseDeclarativeMixin.create_declarative_label
BaseDeclarativeMixin.create_declarative_relation
BaseDeclarativeMixin.create_declarative_child

Note

User should not invoke super().init(). To add attributes and children in an intuitive order, TriliumAlchemy manually traverses a BaseDeclarativeNote subclass’s MRO and invokes decorator-patched inits followed by BaseDeclarativeMixin.init.

Parameters:

attributes: list[BaseAttribute]: List of attributes to which user can append using BaseDeclarativeMixin.create_declarative_label or BaseDeclarativeMixin.create_declarative_relation
children: list[Branch]: List of children to which user can append using BaseDeclarativeMixin.create_declarative_child

create_declarative_label(name: str, value: str = '', inheritable: bool = False) → Label¶

Inherited from: trilium_alchemy.core.declarative.base.BaseDeclarativeMixin

Create and return a Label with deterministic attribute_id based on its name and note’s note_id. Should be used in subclassed BaseDeclarativeNote.init or BaseDeclarativeMixin.init to generate the same attribute_id upon every instantiation.

Multiple attributes of the same name are supported.

create_declarative_relation(name: str, target: Note, inheritable: bool = False) → Relation¶

Inherited from: trilium_alchemy.core.declarative.base.BaseDeclarativeMixin

Create and return a Relation with deterministic attribute_id based on its name and note’s note_id. Should be used in subclassed BaseDeclarativeNote.init or BaseDeclarativeMixin.init to generate the same attribute_id upon every instantiation.

Multiple attributes of the same name are supported.

Inherited from: trilium_alchemy.core.declarative.base.BaseDeclarativeMixin

Creates a child BaseDeclarativeNote with deterministic note_id and returns a Branch. Should be used in subclassed BaseDeclarativeNote.init or BaseDeclarativeMixin.init to generate the same child note_id upon every instantiation.

If the parent note’s note_id set, the child note will be assigned one so as to create the same note_id upon every instantiation.

If the child’s note_id is not fixed, a new note will be created upon every instantiation. This is the case for non-singleton subclasses.

Params following child_cls are passed to the Note and Branch initializers.

Parameters:

child_cls: type[BaseDeclarativeNote]: Class of child to instantiate

class trilium_alchemy.core.declarative.base.BaseDeclarativeMixin(session: Session)¶

Bases:

abc.ABC
trilium_alchemy.core.session.SessionContainer

Aliases:

trilium_alchemy.BaseDeclarativeMixin
trilium_alchemy.core.BaseDeclarativeMixin
trilium_alchemy.core.declarative.BaseDeclarativeMixin

Reusable collection of attributes and children which can be inherited by a BaseDeclarativeNote.

icon: str | None¶

None

If provided, adds #iconClass label unless it is already present.

init(attributes: list[BaseAttribute], children: list[Branch])¶

Can be overridden to add attributes and/or children during instantiation. Use the following to create attribute/child with deterministic id:

BaseDeclarativeMixin.create_declarative_label
BaseDeclarativeMixin.create_declarative_relation
BaseDeclarativeMixin.create_declarative_child

Note

Parameters:

attributes: List of attributes to which user can append using BaseDeclarativeMixin.create_declarative_label or BaseDeclarativeMixin.create_declarative_relation
children: List of children to which user can append using BaseDeclarativeMixin.create_declarative_child

create_declarative_label(name: str, value: str = '', inheritable: bool = False) → Label¶

Multiple attributes of the same name are supported.

create_declarative_relation(name: str, target: Note, inheritable: bool = False) → Relation¶

Multiple attributes of the same name are supported.

If the parent note’s note_id set, the child note will be assigned one so as to create the same note_id upon every instantiation.

If the child’s note_id is not fixed, a new note will be created upon every instantiation. This is the case for non-singleton subclasses.

Params following child_cls are passed to the Note and Branch initializers.

Parameters:

child_cls: type[BaseDeclarativeNote]: Class of child to instantiate
