建立评论的对象关系映射：
class Comment(db.Model):
__tablename__=‘comment‘
class Comment(db.Model):
__tablename__ = ‘comment‘
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
author_id = db.Column(db.Integer, db.ForeignKey(‘user.id‘))
question_id = db.Column(db.Integer, db.ForeignKey(‘question.id‘))
detail = db.Column(db.Text, nullable=False)
create_time = db.Column(db.DateTime, default=datetime.now)
question = db.relationship(‘Question‘, backref=db.backref(‘comments‘,order_by=create_time.desc))
author = db.relationship(‘User‘, backref=db.backref(‘comments‘))
尝试实现发布评论。
