refactor nits

nit: can early return the cached_latest_release if cached_latest_release is not None

[cathteng]

you can grab the environment object itself via workflow.environment, that way you don't have to re-lookup the environment on line 25, and use environment.id when you need the id

line 25:

environments = [Environment.objects.get(id=environment_id)]

[cathteng]

we could slightly rewrite this? this is because first() either returns the object or None

Suggested change

	latest_release = Release.objects.filter(
	version=latest_release_version, organization_id=organization_id
	).first()
	if latest_release:
	cache.set(cache_key, latest_release, 600)
	return latest_release
	else:
	cache.set(cache_key, False, 600)
	latest_release = Release.objects.filter(
	version=latest_release_version, organization_id=organization_id
	).first()
	cache.set(cache_key, latest_release or False, 600)
	return latest_release
