在 mongoengine 中更新嵌入的文档 [英] Updating an embedded document in mongoengine

问题描述

我有一个 mongoengine 课程

I have a class in 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))

我正在尝试从某个父"更新 Post EmbeddedDocument 属性名称文本.文档.作为第一步，我检索 Feed 文档

I am trying to update the Post EmbeddedDocument property name text from a certain "Parent" document. As a first step, I retrieve the Feed Document

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

然后我想更新嵌入文档Post"的属性文本.

and then I want to update the property text of the embedded document "Post".

我怎样才能用 mongoengine 实现它?谢谢

How can I achieve it with mongoengine? Thanks
