BackwardCompatibleChanGo

class chango.concrete.BackwardCompatibleChanGo(main_instance, legacy_instances)

Bases: ChanGo[BackwardCompatibleVersionScanner, VHT, VNT, CNT], Generic

An Implementation of the ChanGo interface that wraps multiple other implementations of ChanGo. The purpose of this class is to ease transition between different version note formats in a project.

Parameters:

• main_instance (ChanGo) – The ChanGo instance that should be used for new version notes.

• legacy_instances (Collection[ChanGo]) – A collection of ChanGo instances that should be used for loading older version notes.

build_github_event_change_note(event, data=None)

Calls build_github_event_change_note() on main_instance.

build_template_change_note(slug, uid=None)

Calls build_template_change_note() on main_instance.

build_version_history()

Calls build_version_history() on main_instance.

build_version_note(version)

Calls build_version_note() on main_instance or one of the legacy instances depending on the result of is_available().

get_write_directory(change_note, version)

Calls get_write_directory() on main_instance.

load_change_note(uid)

Load a change note with the given identifier. Tries to load the change note from the main chango first and then from the legacy changos.

property scanner

The BackwardCompatibleVersionScanner instance that is used by this BackwardCompatibleChanGo.

Hint

The scanner is a composite of the scanners of main_instance and legacy_instance.
