我正在尝试为 Django 项目创建测试装置。

我有一个Question 子对象和一个Node 父对象。

由于某些自定义管理器，无法使用manage.py dumpdata捕获父对象 Node 。

我正在尝试创建自己的夹具转储管理命令来捕获父对象和子对象。

如何将更多对象附加到 json 夹具文件？

import json
from django.core import serializers
try:
    original_dump = open(dump_file.name)

    data_list = []
    for object in serializers.deserialize('json', original_dump):
        data_list.append(object)

except IOError:
    print "I can't open your file"

from forum.models import Node
for node in Node.objects.all():
    data_list.append(node)

serialized_list = serializers.serialize('json', data_list)

write_file = open(dump_file.name, "w")
write_file.write(serialized_list)
write_file.close()

这是节点管理器代码： 

class NodeManager(CachedManager):
    use_for_related_fields = True

    def get_query_set(self):
        qs = NodeQuerySet(self.model)

        # If the node is an answer, question or comment we filter the Node model by type
        if self.model is not Node:
            qs = qs.filter(node_type=self.model.get_type())

        return qs

    def get_for_types(self, types, *args, **kwargs):
        kwargs['node_type__in'] = [t.get_type() for t in types]
        return self.get(*args, **kwargs)

    def filter_state(self, **kwargs):
        return self.all().filter_state(**kwargs)

为什么父对象节点没有被写入serialized_list？
