基类：object

Thin wrapper around sqlite for workflows/templates. Thread-safe for FastAPI (uses check_same_thread=False). Keep SQL in one place.

__init__(db_path: Path)

init_schema() → DB

insert_workflow(name: str, file_path: Path, cover: Optional[str] = None, requirements: Optional[str] = None) → str

Insert workflow row for a new file. Returns id (uuid).

update_workflow_metadata(id: str, name: str, file_path: Path, cover: Optional[str] = None, requirements: Optional[str] = None) → None

Update metadata (name/ext/size/cover/requirements) of a workflow row by id.

upsert_workflow_by_path(file_path: Path, name: str, cover: Optional[str] = None, requirements: Optional[str] = None) → str

Ensure a row exists for the given file path; if exists, update metadata; if not, insert a new row. Returns id.

get_workflow_path(id_: str) → Optional[Path]

get_workflow_name(id_: str) → Optional[Path]

get_workflow_id_and_cover_by_path(file_path: Path) → Optional[Tuple[str, Optional[str]]]

delete_workflow(id_: str) → bool

insert_or_ignore_template(file_path: Path, cover: Optional[str] = None, category: Optional[str] = None, requirements: Optional[str] = None) → None

get_template_path(id_: str) → Optional[Path]

get_template_meta_by_path(file_path: Path) → Optional[Tuple[str, Optional[str], Optional[str]]]

Returns (id, cover, requirements, category) for a template path.

cursor() → Cursor
