1.准备视图函数search()
2.修改base.html 中搜索输入框所在的
a.<form action="{
{ url_for('search') }}" method="get">b.<input name="q" type="text" placeholder="请输入关键字">
3.完成视图函数search()
a.获取搜索关键字
q = request.args.get('q’)b.条件查询
qu = Question.query.filter(Question.title.contains(q)).order_by('-creat_time’)c.加载查询结果:
return render_template('index.html', question=qu)4.组合条件查询
from sqlalchemy import or_, and_@app.route('/search/')def search(): qu = request.args.get('q') ques = Question.query.filter( or_( Question.title.contains(qu), Question.detail.contains(qu) ) ).order_by('-create_time') return render_template('index.html',question = ques)
