akvo.rsr.models.tree.usecases module

akvo.rsr.models.tree.usecases.check_set_parent(node: AkvoTreeModel, new_parent: AkvoTreeModel)

akvo.rsr.models.tree.usecases.delete_parent(node: AkvoTreeModel) → AkvoTreeModel

Delete parent and update the descendants

akvo.rsr.models.tree.usecases.set_parent(node: AkvoTreeModel, new_parent: AkvoTreeModel, force: bool = False)

Only force if you’re sure you won’t break anything!

akvo.rsr.models.tree.usecases.update_descendant_parents(old_path: PathValue, new_parent: AkvoTreeModel, force: bool = False) → List[AkvoTreeModel]

Basically updates a given tree and makes this node the parent

Made private as it has the potential to destroy trees and shouldn’t be called willy-nilly.

Parameters:

• old_path – The old path to this node that can be used to find old descendants

• new_parent –

• force – For the parent to be set and don’t do checks

Returns:

The updated descendants (may or may not be reflected in the DB depending on save)
