通过annotate从字典列表return中获取name键的值,然后按name排序?

Get the value of name key from the list of dictionaries return by the annotate and then sort by name?

我的代码

def get_areas(self, obj):
        text = []
        if obj.areas and not obj.areas == []:
            print(json.loads(obj.area_count))
            print(type(obj.area_count))
            return json.loads(obj.area_count)
        return "-"

get_areas.short_description = "Areas"
get_areas.admin_order_field= "area_count"

def get_queryset(self, request):
        from django.contrib.postgres.fields.jsonb import KeyTextTransform
        qs = super(UserAdmin, self).get_queryset(request)
        filtered_query = qs.filter(
            is_superuser=False, is_staff=False
        ).annotate(
            wishlist_count=Count('wishlist', distinct=True),
            booking_count=Count('booking', distinct=True),
            review_count=Count('review', distinct=True),
            suggestion_count=Count('suggestion', distinct=True),
            home_city=NullIf('home__city'),
            home_country=NullIf('home__country'),              
            area_count = F('areas'),

        )

我得到的是一个 str 类型的列表,类似于:

"[{'id': 98, 'name': 'Khalifa City and Masdar City', 'city': 'Abu Dhabi'},
{'id': 99, 'name': 'Masdar City', 'city': 'Abu Dhabi'}]"
<class 'str'>

我想要的是姓名列表:

['Khalifa City and Masdar City','Madsar City']

那么,如何将 return area_count = F('areas') 的结果作为 list 而不是 str

注意:该列表可以包含超过 1 个词典,我想 return 只是 names.Any 的努力将不胜感激

您需要 F("areas")annotate 做什么?

只需删除它并访问 "areas" 作为 QS 中对象的属性。
