如今音乐已经成为人们尤其是年轻人的日常必备。走路，坐车，逛街，我们都能看到戴着耳机听音乐的人。古风曲、日韩风、欧美风、hippop等等各种音乐风格多样。随着媒体的发展，微博微信公众号媒体采访等等的发展，人们对音乐的理解也开始不只是限于听，越来越多的人开始了解歌曲背后的含义的故事。每首歌曲背后都有着不一样的情感和故事，每首歌都代表着不一样的经历和成长。总有歌曲里似乎有着我们的身影和故事，在某个瞬间已是如同曲中人。
发现歌曲背后的故事，聊聊属于我们的感受和想法，分享藏着我们记忆和故事的那些歌。在音乐的世界中，放松自己，了解自己，也学会好好爱自己和珍惜身边的人。

4.数据库设计
设计5个数据表分别为：
1.User表：用于存储用户注册的用户数据
class User(db.Model): __tablename__ = ‘user‘ # 建立一个表user id = db.Column(db.Integer, primary_key=True, autoincrement=True) username = db.Column(db.String(20), nullable=False) _password = db.Column(db.String(200), nullable=False) say = db.Column(db.String(50)) icon = db.Column(db.String(50)) collection = db.relationship(‘Question‘, secondary=Collection, backref=db.backref(‘user‘, lazy=‘dynamic‘), lazy=‘dynamic‘)
2.Question表：用于存储用户发布帖子的数据，包括帖子的标题、内容、发贴时间、发帖用户、类别、点赞数和浏览量
class Question(db.Model): __tablename__ = ‘question‘ id = db.Column(db.Integer, primary_key=True, autoincrement=True) title = db.Column(db.String(100), nullable=False) detail = db.Column(db.Text, nullable=False) creat_time = db.Column(db.DateTime, default=datetime.now) author_id = db.Column(db.Integer, db.ForeignKey(‘user.id‘)) cf = db.Column(db.Integer, db.ForeignKey(‘cf.id‘)) look = db.Column(db.Integer) click = db.Column(db.Integer) author = db.relationship(‘User‘, backref=db.backref(‘question‘)) cfClass = db.relationship(‘Cf‘, backref=db.backref(‘question‘))
3.Comment表：用于存储用户的评论数据，包括评论内容、评论时间、评论的用户、评论的帖子
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‘)) creat_time = db.Column(db.DateTime, default=datetime.now()) detail = db.Column(db.TEXT, nullable=False) question = db.relationship(‘Question‘, backref=db.backref(‘comment‘)) author = db.relationship(‘User‘, backref=db.backref(‘comment‘, order_by=creat_time.desc))
4.Cf表：识别和存储帖子的类型
class Cf(db.Model): __tablname__ = ‘cf‘ id = db.Column(db.Integer, primary_key=True, autoincrement=True) name = db.Column(db.String(30)) context = db.Column(db.TEXT)
5.Collection表：存储对应用户收藏的帖子
Collection = db.Table( ‘collection‘, db.Column(‘id‘, db.Integer, primary_key=True, autoincrement=True) db.Column(‘book_id‘, db.Integer, db.ForeignKey(‘question.id‘))
db.Column(‘collection‘, db.Integer, db.ForeignKey(‘user.id‘)) db.Column(‘createdate‘, db.DATETIME) )
5.系统展示的关键算法与数据结构
1.登录注册：
@app.route(‘/login/‘, methods=[‘GET‘, ‘POST‘]) def login(): if request.method == ‘GET‘: return render_template(‘login.html‘) else: username = request.form.get(‘username‘) password = request.form.get(‘password‘) user = User.query.filter(User.username == username).first() if user: if user.check_password(password): session[‘username‘] = user.username session[‘user_id‘] = user.id session.permanent = True # 重新定位到首页 return redirect(url_for(‘index‘)) else: # 重新定位到注册 return ‘用户不存在或密码错误‘ else: return redirect(url_for(‘login‘)) # 注册 @app.route(‘/register/‘, methods=[‘GET‘, ‘POST‘]) def regist(): if request.method == ‘GET‘: return render_template(‘regist.html‘) else: username = request.form.get(‘username‘) password = request.form.get(‘password‘) user = User.query.filter(User.username == username).first() if user: return "账号已存在" else: user = User(username=username, password=password) db.session.add(user) db.session.commit() return redirect(url_for(‘login‘))
2.发布帖子：
@app.route(‘/question‘, methods=[‘GET‘, ‘POST‘]) @loginFirst def question(): if request.method == ‘GET‘: cf = Cf.query.all() return render_template(‘question.html‘, cf=cf) else: title = request.form.get(‘title‘) detail = request.form.get(‘detail‘) # author_id = request.form.get(‘author_id‘) author_id = User.query.filter(User.username == session.get(‘username‘)).first().id cf = request.form.get(‘cf‘) question = Question(title=title, detail=detail, author_id=author_id, cf=cf) db.session.add(question) # 加入数据库 db.session.commit() return redirect(url_for(‘index‘))
3.详情页跳转：
@app.route(‘/detail/<question_id>‘, methods=[‘GET‘, ‘POST‘]) # @loginFirst def detail(question_id): quest = Question.query.filter(Question.id == question_id).first() u = User.query.filter(User.id == session.get(‘user_id‘)).first() if request.method == ‘POST‘: if request.form.get(‘click‘) == ‘1‘: quest.click = quest.click + 1 if request.form.get(‘collection‘) == ‘1‘: user = u user.collection.append(quest) db.session.add(user) col = u.collection.filter_by(id=question_id).first() if col is None: col = {} comment = Comment.query.filter(Comment.question_id == question_id).order_by(‘-creat_time‘).all() quest.look = quest.look + 1 content = { ‘ques‘: quest, ‘comment‘: comment, ‘col‘: col, ‘questions‘: Question.query.filter(Question.cf == quest.cf).all(), } return render_template(‘detail.html‘,**content)
4.发表评论：
@app.route(‘/answer/‘, methods=[‘GET‘, ‘POST‘]) def answer(): if request.method == ‘POST‘: question_id = request.form.get(‘question_id‘) author_id = request.form.get(‘author_id‘) detail = request.form.get(‘detail‘) comment = Comment(question_id=question_id, author_id=author_id, detail=detail) db.session.add(comment) db.session.commit() return redirect(url_for(‘detail‘, question_id=question_id))
5.搜索：
