可获取到model中query多对多的完整数据
query = queryset.order_by(ordering).first()
for topic in query._meta.many_to_many:
lista = list(topic.value_from_object(query).values_list('pk', flat=True))
for lis in lista:
data[lis] = TopicType.objects.filter(id=lis).first().name
u_query[topic.name] = data
数据model转dict
from django.forms.models import model_to_dict
query = queryset.order_by(ordering).first()
u_query = model_to_dict(query)
print(u_query)
输出后为query的所有数据的子层,模型中ForeignKey，OneToOneField， ManyToManyField关联的内容只展示其id
