小编trs*_*anx的帖子

所以我的模型很简单

class Face(models.Model):
    uid = models.CharField(max_length=510, primary_key=True)
    photo = models.ImageField(upload_to='face_photos')

串行器

class FaceSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Face
        fields = ['uid', 'photo']
        extra_kwargs = {'uid': {'required': True}, 'photo': {'required': True}}

视图应该是这样的

class FaceViewSet(viewsets.ModelViewSet):
    queryset = Face.objects.all()
    serializer_class = FaceSerializer
    permission_classes = [permissions.AllowAny]

它有效。然而：

1. 我不需要列出、更新、删除选项。仅 POST 和 GET。
2. 我想在帖子中添加我的逻辑，因此如果uid存在则更新，否则创建......以及其他处理。
3. 我想要在 POST 之后自定义响应。

我如何实现这一切而不失去提供的所有好处viewsets.ModelViewSet，例如验证、Rest API Web 视图中自动生成的 HTML 字段等？

from z3 import *

p = Int('p')
q = Int('q')

solve(Or(p==1,p==2,p==3), Or(q==1,q==2), Not(p==q), q==1)

给我[p = 2, q = 1]，但 p 可能是 2 或 3。所以答案应该是 {2,3}。我如何告诉 z3 通知我多个答案？

这是我对哈希图的分析的日志（截断）：

unsigned nbuckets = octree->Nodes.bucket_count();

LOG(Error, "bucket size = {0}, kk = {1}", nbuckets, octree->Nodes.max_load_factor());

for (auto& x : octree->Nodes) {
   LOG(Warning, "Element [{0}:{1}] is in bucket {2}", x.first.morton, x.second.position, octree->Nodes.bucket(x.first));
}
