1、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)
2、首页标题的标签做带参数的链接。
{{ url_for(‘detail‘,question_id = foo.id) }}
<a href="{{ url_for(‘detail‘,question_id = foo.id) }}">{{ foo.title }}</a>
3、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 }
{% for foo in questions %} <li class="list-group-item"> <span class="glyphicon glyphicon-leaf" aria-hidden="true"></span> <a href="{{ url_for(‘detail‘,question_id = foo.id) }}">{{ foo.title }}</a> <p style="">{{ foo.detail }}</p> <span class="glyphicon glyphicon-user" aria-hidden="true"></span> <a href="">{{ foo.author.username }}</a> <span class="badge">{{ foo.creat_time }}</span> </li> {% endfor %}
4、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‘))
creat_time = db.Column(db.DateTime,default=datetime.now)
detail = db.Column(db.Text,nullable=False)
question = db.relationship(‘Question‘,backref = db.backref(‘comments‘))
author = db.relationship(‘User‘,backref = db.backref(‘comments‘))
5、 尝试实现发布评论。
