- 主PY文件写视图函数,带id参数。
@app.route(‘/detail/<question_id>‘)
def detail(question_id):
quest =
return render_template(‘detail.html‘, ques = quest)@app.route(‘/detail/<question_id>‘) def detail(question_id): quest = Question.query.filter(Question.id == question_id).first() return render_template(‘detail.html‘,ques = quest)
- 首页标题的标签做带参数的链接。
{{ url_for(‘detail‘,question_id = foo.id) }}{% extends‘base.html‘ %} {% block title %} 首页 {% endblock %} {% block head %} <script src="{{url_for(‘static‘,filename=‘js/base.js‘) }}" type="text/javascript"></script> <link href="{{ url_for(‘static‘ ,filename=‘css/base.css‘) }}" rel="stylesheet" type="text/css"> {% endblock %} {% block main %} {% for foo in question %} <body id="myBody"> <div id="linnnfeng"> <ul class="list" > <li>用户名:{{ foo.author.username }}</li> <a href="{{ url_for("detail",question_id=foo.id) }}">标题:{{ foo.title }}</a> <li class="">疑问:{{ foo.detail }}</li> <li class="">时间:{{ foo.time }}</li> </ul> </div> {% endfor %} <footer> <div class="footer_box"> [email protected] 个人版权,版权所有 作者:LinF telephone:0000-1234567 mobile phone:11111111111 </div> </footer> {% endblock %}
- 在详情页将数据的显示在恰当的位置。
{{ ques.title}}
{{ ques.id }}{{ ques.creat_time }}{{ ques.author.username }}
{{ ques.detail }}{% block main %} <ul class="list"> <p class="title">{{ ques.title }}</p> <a href="usern">{{ ques.author.username }}</a> <p class="answer" style="text-indent: 18px">{{ ques.detail }}</p> <span class="badge">{{ ques.creat_time }}</span> <a href="a">回复</a> <div> <input id="fabu" name="comment" type="submit" placeholder="请输入要发布的内容" > <form action="{{ url_for(‘comment‘) }}" method="post"> <button>发送</button> </form> </div> </ul> {% endblock %}
-
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‘))
-
