Bases: spinetoolbox.spine_db_editor.mvcmodels.multi_db_tree_model.MultiDBTreeModel

An ‘object-oriented’ tree model.

Init class.

Parameters

parent (SpineDBEditor) –
db_mngr (SpineDBManager) – A manager for the given db_maps
db_maps (iter) – DiffDatabaseMapping instances

property root_item_type(self)[source]¶: Implement in subclasses to create a model specific to any entity type.

_parent_object_data(self, db_map_data)[source]¶

Takes given object data and returns the same data keyed by parent tree-item.

Parameters: db_map_data (dict) – maps DiffDatabaseMapping instances to list of items as dict
Returns: maps parent tree-items to DiffDatabaseMapping instances to list of item ids
Return type: dict

_parent_relationship_class_data(self, db_map_data)[source]¶

Takes given relationship_class data and returns the same data keyed by parent tree-item.

Parameters: db_map_data (dict) – maps DiffDatabaseMapping instances to list of items as dict
Returns: maps parent tree-items to DiffDatabaseMapping instances to list of item ids
Return type: dict

_parent_relationship_data(self, db_map_data)[source]¶

Takes given relationship data and returns the same data keyed by parent tree-item.

Parameters: db_map_data (dict) – maps DiffDatabaseMapping instances to list of items as dict

Takes given entity group data and returns the same data keyed by parent tree-item.

Parameters: db_map_data (dict) – maps DiffDatabaseMapping instances to list of items as dict
Returns: maps parent tree-items to DiffDatabaseMapping instances to list of item ids
Return type: dict
