	# When you have do an SQL"IN" operation, we generally do it like this. ie, convert the results to a list.
	# DON'T DO THIS
	seasons = list(Season.objects.values_list('name', flat=True))
	result = Crops.objects.filter(season__name__in=seasons)
	print(result)

	# SELECT * FROM crops c inner join season s on c.season_id = s.id where s.name in ('winter', 'summer', ...)
