在mongoengine中更新嵌入式文档 [英] Updating a embedded documents in mongoengine

问题描述

我有一个mongoengine类

I have a class mongoengine

class Post(EmbeddedDocument):
        uid = StringField(required=True)
        text = StringField(required=True)
        value = StringField()

class Feed(Document):
        label = StringField(required=True)
        feed_url = StringField(required=True)
        posts = ListField(EmbeddedDocumentField(Post))

我正在尝试更新Feed中的元素(帖子) 第一个:我得到一个对象Feed

I am trying update a element in Feed(posts) The first: I get a object Feed

model = Feed.objects(_id="....").first()

继续，我要更新模型中的帖子的文字="title".

Continue I want update Post in model have text = "title".

我如何使用mongoengine做到这一点?谢谢
