How do we determine which version of a related matter is "active"?

[hancush]

We introduced logic in #112 to retrieve the most recent version of every matter relation. This relies on the assumption that the most recent version is the active version, but per Metro-Records/la-metro-councilmatic#669 (comment), this is not always the case. Omar thought Regina might have implemented some logic to determine which version is active, but I can't find it.

The revised implementation exposes a method to apply a different filter to matter relations, so maybe this is a question we allow users of this library to answer themselves:

python-legistar-scraper/legistar/bills.py

Lines 424 to 448 in 83cb634

	def _filter_relations(self, relations):
	'''
	Sometimes, many versions of a bill are related. This method returns the
	most recent version of each relation. Override this method to apply a
	different filter or return the full array of relations.
	'''
	# Sort relations such that the latest version of each matter
	# ID is returned first.
	sorted_relations = sorted(
	relations,
	key=lambda x: (
	x['MatterRelationMatterId'],
	x['MatterRelationFlag']
	),
	reverse=True
	)
	seen_relations = set()
	for relation in sorted_relations:
	relation_id = relation['MatterRelationMatterId']
	if relation_id not in seen_relations:
	yield relation
	seen_relations.add(relation_id)
