python - 如何更新 Graphite 烯mongo python中EmbeddedDocument的字段

Question

我正在尝试更新 IgThread EmbeddedDocument 的一个字段，并且发生错误:“IgThread”对象没有属性“save”

我尝试了一些奇怪的解决方案，但没有一个有效。当前代码存在错误

突变:

def mutate(self, _, **kwargs):
    ig_pk = kwargs['ig_pk']
    thread_input = kwargs['ig_thread']

    lead_ = Lead.objects(ig__pk=ig_pk).first()

    for thread in lead_.messages.ig:

        Lead.objects(
            ig__pk=ig_pk,
            messages__ig__thread_id=thread_input.thread_id,
        ).update(
            push_all__messages__ig__S__messages=new_messages,
        )

        thread.last_activity_at = thread_input.last_activity_at
        thread.save()

父级:

class Lead(Document):
    id = fields.ObjectIdField()
    messages = fields.EmbeddedDocumentField(Messages)

嵌套嵌入文档:

class Messages(EmbeddedDocument):
    ig = fields.EmbeddedDocumentListField(IgThread)

更深入:

class IgThread(EmbeddedDocument):
    thread_id = fields.StringField()
    last_activity_at = fields.StringField()

我想更新last_activity_at请帮忙，我必须修复这个错误，但在办公室里没有人能帮我解决这个问题:<

解决了!这很容易...

def mutate(self, _, **kwargs):
    ig_pk = kwargs['ig_pk']
    thread_input = kwargs['ig_thread']

    lead_ = Lead.objects(ig__pk=ig_pk).first()

    for thread in lead_.messages.ig:

        Lead.objects(
            ig__pk=ig_pk,
            messages__ig__thread_id=thread_input.thread_id,
        ).update(
            push_all__messages__ig__S__messages=new_messages,
        )

        lead_ = Lead.objects(ig__pk=ig_pk).first() <--------
        thread.last_activity_at = thread_input.last_activity_at
        lead_.save() <--------
