分别得到1,2,3,4,5星平均(1星%+2星%+3星%+4星%+5星%=100%)

Get 1,2,3,4,5 star average individually (1star% +2star% +3star% +4star% +5star%=100%)

假设我给一个用户评分 1 星 3 次,2 星 1 次,4 星 4 次,5 星 10times.now 从这里任何人都可以找出总体平均评分,但我如何获得 1 星、2 星的百分比,3星,4星和5星总评分 #以django方式显示它

    rating = Rating.objects.filter(activity__creator=u)
    one_star_count = rating.filter(star='1').count()
    two_star_count = rating.filter(star='2').count()
    three_star_count = rating.filter(star='3').count()
    four_star_count = rating.filter(star='4').count()
    five_star_count = rating.filter(star='5').count()

    total_stars_count = one_star_count + two_star_count+ \
    three_star_count + four_star_count+ five_star_count

在您的 User 模型方法中创建计算百分比的方法,然后根据需要简单地使用它:

class User(...):
    ...
    def count_star_precentage(self, star):
        return (Rating.objects.filter(activity__creator=self, star=star).count() / self.all_ratings().count()) * 100

    def all_ratings(self):
        return Rating.objects.filter(activity__creator=self)

有了他们,您可以通过简单的调用获得百分比:

 user = User.objects.get(id=some_id)
 user.count_star_precentage(3)    # it will give the percent of total ratings with 3 star given by that user
