Question

我正在尝试在admin.py操作中更新扩展用户模型profile。我现在已经研究了几个小时了，并且做得很短。我收到pc_add_1() missing 1 required positional 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

Answer 1

您的方法签名错误：

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

对于管理员操作，它应该是

def pc_add_1(self, request, queryset):

现在，如果你想知道哪个管理员用户正在进行更改，你可以从request.user

找到

Answer 2

您必须从行

中删除参数user

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

Django将仅使用request和queryset调用该方法。您将能够通过request.user获得用户。

缺少1个必需的位置参数：'queryset'
