1.定义评论的视图函数
@app.route(‘/comment/‘,methods=[‘POST‘])
def comment()：
读取前端页面数据，保存到数据库中
@app.route(‘/comment/‘, methods=[‘POST‘])
@log
def comment():
comment = request.form.get("new_comment")
question_id = request.form.get("question_id")
author_id = User.query.filter(User.username == session.get(‘user‘)).first().id
comm = Comment(author_id=author_id,question_id=question_id,detail=comment)
db.session.add(comm)
db.session.commit()
context = {
‘comments‘: Comment.query.order_by(‘creat_time‘).all()
}
question = Question.query.filter(Question.id == question_id).first()
return render_template(‘detail.html‘, ques=question, **context)
2.用<input type="hidden" 方法获取前端的"question_id"
<input name="question_id" type="hidden" value="{{ ques.id }}"/>
3.显示评论次数
<h4>评论:（{{ ques.comments|length }}）</h4>
4.要求评论前登录
@log
5.尝试实现详情页面下的评论列表显示
<ul class="list-group">
{% for b in comments %}
<li class="list-group-item" >
<a href="#">{{ b.author.username }}</a> <span class="badge">{{ b.creat_time }}</span>
<p class="abstract">{{ b.detail }}</p>
</li>
{% endfor %}
</ul>
