Question

I have Document with EmbeddedDocument like this in mongoengine.
how can create ReferenceField in EmbeddedDocument for Master Document … master Document means that embed my EmbeddedDocument

class Activity(EmbeddedDocument):
    user = ReferenceField(Profile)
    followed_user = ReferenceField(Profile)
    created_date = DateTimeField(default=datetime.datetime.now, required=True)


class Profile(Document):
    username = StringField(max_length=255, required=True)
    password = StringField(max_length=255, required=True)
    email = StringField(max_length=255, required=True)
    activities = ListField(EmbeddedDocumentField(Activity))

Python said:

 NameError: name 'Profile' is not defined

Answer 1

must use self in EmbeddedDocuments too

class Activity(EmbeddedDocument):
    user = ReferenceField('Profile')
    user_unrelated = ReferenceField('Profile')
    created_date = DateTimeField(default=datetime.datetime.now, required=True)
