class spinetoolbox.spine_db_editor.mvcmodels.empty_models.EmptyModelBase(parent)

Bases: spinetoolbox.mvcmodels.empty_row_model.EmptyRowModel

Base class for all empty models that go in a CompoundModelBase subclass.

Parameters

parent (CompoundModelBase) – the parent model

abstract property item_type

property field_map

property can_be_filtered

add_items_to_db(db_map_data)

Add items to db.

Parameters

db_map_data (dict) – mapping DiffDatabaseMapping instance to list of items

abstract _make_unique_id(item)

Returns a unique id for the given model item (name-based). Used by handle_items_added to identify which rows have been added and thus need to be removed.

accepted_rows()

db_item(_index)

item_id(_row)

handle_items_added(db_map_data)

Runs when parameter definitions or values are added. Finds and removes model items that were successfully added to the db.

batch_set_data(indexes, data)

Sets data for indexes in batch. If successful, add items to db.

_autocomplete_row(db_map, item)

Fills in entity_class_name whenever other selections make it obvious.

abstract _entity_class_name_candidates(db_map, item)

_make_item(row)

_make_db_map_data(rows)

Returns model data grouped by database map.

Parameters

rows (set) – group data from these rows

Returns

mapping DiffDatabaseMapping instance to list of items

Return type

dict

data(index, role=Qt.ItemDataRole.DisplayRole)

Returns the data stored under the given role for the item referred to by the index.

Parameters

• index (QModelIndex) – Index of item

• role (int) – Data role

Returns

Item data for given role.
