Django REST 框架 3.1 - PUT-as-create mixin class，自定义 lookup_field

Question

利用 PUT-as-create mixin class 提供 HERE (class AllowPUTAsCreateMixin):

class Tree(models.Model):   
   myfield = models.CharField(max_length=100,unique=True)
   species = models.CharField(max_length=100, blank=True, default='')

class TreeSerializer(serializers.ModelSerializer):
    class Meta:
        model = Tree
        fields = ('myfield', 'species')
        lookup_field = 'myfield'

class TreeView(viewsets.ModelViewSet, AllowPUTAsCreateMixin):

     queryset = Tree.objects.all()
     serializer_class = TreeSerializer
     lookup_field = 'myfield'

     def update(self, request, myfield=None):
        return AllowPUTAsCreateMixin.update(self, request, lookup_field='myfield')

class AllowPUTAsCreateMixin(object):

     def update(self, request, *args, **kwargs):
          lookup_field = kwargs.pop('lookup_field')

当以 JSON 提交数据时（使用 httpie）：

http PUT 127.0.0.1:8000/xxx/trees/123456 < tree.json

对象已创建并公开 @/.../trees/{myfield}

完成！
