python - 缺少 1 个必需的位置参数 : 'queryset'

Question

我正在尝试更新 admin.py 操作中的扩展用户模型配置文件。我已经研究这个问题几个小时了，但效果还不够。我收到 pc_add_1() Missing 1 requiredpositional argument: 'queryset' 错误，请帮忙。

class ProfileAdminInLine(admin.StackedInline):
    model = Profile


class ProfileAdmin(UserAdmin):
    list_display = ['username', 'email', 'first_name', 'last_name', 'is_staff',
                    'rewards_punch_card', 'rewards_tier', 'credits']
    list_select_related = True
    inlines = [ProfileAdminInLine]

    actions = ['pc_add_1', 'pc_add_2', 'pc_add_3', 'pc_add_4', 'pc_add_5',
               'pc_add_6', 'pc_add_7', 'pc_add_8', 'pc_add_9']

    def rewards_tier(self, user):
        return user.profile.rewards_tier

    def rewards_punch_card(self, user):
        return user.profile.rewards_current

    def pc_add_1(self, request, user, queryset):

        punch_card = user.profile.rewards_current
        tier = user.profile.rewards_tier
        credits = user.profile.rewards_credits

        punch_cards_updated = queryset.update(punch_card + 1)

        if punch_cards_updated == 10:
            queryset.update(punch_card == 0)
            if tier == 1:
                queryset.update(tier + 1)
                queryset.update(credits + 25)
            elif tier == 2:
                queryset.update(tier + 1)
                queryset.update(credits + 35)
            elif tier == 3:
                queryset.update(tier + 1)
                queryset.update(credits + 45)
            elif tier == 4:
                queryset.update(tier + 1)
                queryset.update(credits + 55)
            elif tier == 5:
                queryset.update(credits + 65)
            elif tier == 6:
                queryset.update(credits + 65)

        else:
            pass

您的方法签名错误:

def pc_add_1(self, request, user, queryset):

对于管理操作，应该是

def pc_add_1(self, request, queryset):

现在，如果您想知道哪个管理员用户正在进行更改，您可以从 request.user 中找到
