class spinetoolbox.spine_db_editor.mvcmodels.empty_parameter_models.EmptyParameterModel(parent, header, db_mngr)

Bases: spinetoolbox.mvcmodels.empty_row_model.EmptyRowModel

An empty parameter model.

Initialize class.

Parameters:

• parent (Object) – the parent object, typically a CompoundParameterModel
• header (list) – list of field names for the header
• db_mngr (SpineDBManager) –

item_type

The item type, either ‘parameter_value’ or ‘parameter_definition’, required by the json_fields property.

entity_class_type

Either ‘object_class’ or ‘relationship_class’.

entity_class_id_key

entity_class_name_key

can_be_filtered

json_fields

accepted_rows(self)

db_item(self, _index)

item_id(self, _row)

flags(self, index)

Return default flags except if forcing defaults.

data(self, index, role=Qt.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.

_make_unique_id(self, item)

Returns a unique id for the given model item (name-based). Used by receive_parameter_data_added.

receive_parameter_data_added(self, 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(self, indexes, data)

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

add_items_to_db(self, rows)

Add items to db.

Parameters:rows (set) – add data from these rows

_make_db_map_data(self, rows)

Returns model data grouped by database map.

Parameters:rows (set) – group data from these rows
