将 django 中的 pinax-badges 与积分系统集成

Question

我无法让 pinax-badges 在我的项目中工作。我遵循了在我的应用程序中创建一个 badges.py 文件所提供的最小用法 example：

#badges.py

from pinax.badges.base import Badge, BadgeAwarded
from pinax.badges.registry import badges


class PointsBadge(Badge):
    slug = "points"
    levels = [
      "Bronze",
      "Silver",
      "Gold",
     ]
    events = ["points_awarded",]
    multiple = False

    def award(self, **state):
        user = state["user"]
        points = user.get_profile().points
        if points > 10000:
            return BadgeAwarded(level=3)
        elif points > 7500:
            return BadgeAwarded(level=2)
        elif points > 5000:
            return BadgeAwarded(level=1)


badges.register(PointsBadge)

在我的用户模型中调用 a 的一个非常糟糕的点函数接受一个数量参数并将其添加到我的用户模型中的点字段。

#User Model
class User(AbstractUser):
    ....
    points = models.IntegerField(default=0)

def award_points(self,amount):
    self.amount = amount
    self.points+=amount
    self.save()

现在我在一个信号中调用的函数会检查用户何时登录并奖励他们一些积分。就像这样

#signal.py
from django.contrib.auth.signals import user_logged_in,user_logged_out
from django.dispatch import receiver
from django.conf import settings
from pinax.badges.registry import badges


@receiver(user_logged_in)
def award(sender,request ,user, **kwargs):
    user = request.user.award_points(5000)
    badges.possibly_award_badge("points_awarded", user=user)

为了确定，我也注册了信号。我仍然没有得到想要的结果，也就是说，一旦用户登录并获得 5000 分，这对于 badges.py 文件中定义的 1 级徽章来说已经足够了。 除了信号之外，我不确定是否有更有效的方法来实现此结果，除非当然有人推荐了一种不同的方法。

感谢回复。

我是这样做的。

在 models.py

中

from django.template.defaultfilters import slugify
from django.db import models
from django.contrib.auth.models import User

from pinax.badges.base import Badge, BadgeAwarded
from pinax.badges.registry import badges

class PointsBadge(Badge):
    slug = "points"
    levels = [
        "Bronze",
        "Silver",
        "Gold",
    ]
    events = [
        "points_awarded",
    ]
    multiple = False

    def award(self, **state):
        user = state["user"]
        points = user.profile.points
        if points > 500:
            return BadgeAwarded(level=3)
        elif points > 50:
            return BadgeAwarded(level=2)
        elif points > 5:
            return BadgeAwarded(level=1)

badges.register(PointsBadge)

class Profile(models.Model):
    user = models.OneToOneField(
        User,
        on_delete = models.CASCADE
    )
    points = models.IntegerField (
        default = 0
    )

    def award_points (self, points):
        self.points += points
        self.save()

在 signals.py 我在创建 user 时创建 profile

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)

然后在我的view内

    request.user.profile.award_points(p.points)
    badges.possibly_award_badge("points_awarded", user=request.user)
