评论管理功能

后端

@bp.get("/comment/list")
def comment_list():comments = CommentModel.query.order_by(CommentModel.create_time.desc()).all()comment_list = []for comment in comments:comment_dict = comment.to_dict()comment_list.append(comment_dict)return restful.ok(data=comment_list)@bp.post("/comment/delete")
def delete_comment():comment_id = request.form.get("id")CommentModel.query.filter_by(id=comment_id).delete()return restful.ok()

class CommentModel(db.Model, SerializerMixin):__tablename__ = 'comment'id = db.Column(db.Integer, primary_key=True, autoincrement=True)content = db.Column(db.Text, nullable=False)create_time = db.Column(db.DateTime, default=datetime.now)post_id = db.Column(db.Integer, db.ForeignKey("post.id"))author_id = db.Column(db.String(100), db.ForeignKey("user.id"), nullable=False)post = db.relationship("PostModel", backref=db.backref('comments', order_by="CommentModel.create_time.desc()", cascade="delete, delete-orphan"))author = db.relationship("UserModel", backref='comments')

serialize_only = ("id", "title", "content", "create_time", "board", "author")

在这里插入图片描述

class PostModel(db.Model, SerializerMixin):serialize_only = ("id", "title", "content", "create_time", "board", "author")__tablename__ = "post"id = db.Column(db.Integer, primary_key=True, autoincrement=True)title = db.Column(db.String(200), nullable=False)content = db.Column(db.Text, nullable=False)create_time = db.Column(db.DateTime, default=datetime.now)board_id = db.Column(db.Integer, db.ForeignKey("board.id"))author_id = db.Column(db.String(100), db.ForeignKey("user.id"))# 这里关联了BoardModel 也会将其序列化   所以 BoardModel也需要继承SerializerMixin# 另外 序列化的时候会给BoardModel添加一个属性postsboard = db.relationship("BoardModel", backref=db.backref("posts"))author = db.relationship("UserModel", backref=db.backref("posts"))

前端

getCommentList(){const url = "/comment/list"return this.http.get(url)}deleteComment(comment_id){const url = "/comment/delete"return this._post(url, {"id": comment_id})
