python - Django mongoengine 文档中的 Manytomany 字段

Question

我有以下 Django 模型:

from mongoengine import *
from datetime import datetime

class Company(Document):

    name = StringField(max_length=500)



class Feedback(Document):

    text = StringField(max_length=500)
    is_approved = BooleanField(default=False)
    date = DateTimeField(default=datetime.now())

我想在公司中添加多个反馈字段

提前致谢。

Answer 1

这不是 Django 模型，而是 mongoengine 文档。它没有ManyToManyField。相反，您可能应该在 ListField 内向您的 Company 类添加一个 ReferenceField，如下所示:

class Company(Document):
    name = StringField(max_length=500)
    feedbacks = ListField(ReferenceField(Feedback))

class Feedback(Document):
    text = StringField(max_length=500)
    is_approved = BooleanField(default=False)
    date = DateTimeField(default=datetime.now())
