【问题描述】:
基本上我试图编写一个索引路由来返回用户订阅的业务的帖子 最后一行为 backref (business.posts) 抛出错误
# query that finds all the subscriptions of the logged in user
subscriptions_query = models.Subscription.select().join(models.User).where(models.User.id == current_user.id)
# gets the businesses being followed from the subscriptions
businesses_being_followed = [subscription.following for subscription in subscriptions_query]
post_dicts = [model_to_dict(business.posts) for business in businesses_being_followed]
这是我的帖子模型
class Post(BaseModel):
business = ForeignKeyField(Business, backref='posts')
image = CharField()
content = CharField()
date = DateTimeField(default=datetime.datetime.now)
【问题讨论】:
-
不知道为什么这个问题提到了 backref。
