There are many ways to tackle this problem, and the "best" one depends
on your game's rules. Your above solution would indeed return the
whole history, and you'd need to filter it out to only get the last
value for each skill. A PITA to work with and not exactly efficient...
If it's only for stats and you have no other reason to turn skills
into proper models, the simplest thing would be to add a
"SkillChanged" model, ie (Q&D):
class SkillChange(models.Model):
player = models.ForeignKey(Player)
skill = models.CharField()
value = models.IntegerField()
date = models.DatetimeField(auto_now_add=True)
then detect skill changes using properties (or explicit getters /
setters) to access your Player's class skills fields and create a new
SkillChange for each skill update.
Or use any of the solutions Andre suggested....
