实现搜索功能
- 准备视图函数search()
- 修改base.html 中搜索输入框所在的
- <form action="{{ url_for('search') }}" method="get">
- <input name="q" type="text" placeholder="请输入关键字">
- 完成视图函数search()
- 获取搜索关键字
q = request.args.get('q’) - 条件查询
qu = Question.query.filter(Question.title.contains(q)).order_by('-creat_time’) - 加载查询结果:
return render_template('index.html', question=qu)
- 获取搜索关键字
- 组合条件查询
from sqlalchemy import or_, and_
<form action="{{url_for('search')}}" method="get"class="nav-form navbar-right"> <div class="form-group" style="margin:20px" > <input type="text" name="q" required lay-verify="required" placeholder="请输入搜索内容" autocomplete="off" > <button class="btn btn-default" style="padding-top:5px;" type="submit"><span class="glyphicon glyphicon-search" aria-hidden="true"></span>搜索</button> </div> </form>
@app.route('/search/') @loginFirst def search(): qu=request.args.get('q') ques= Question.query.filter( or_( Question.title.contains(qu), Question.detail.contains(qu), )) # ).order_by('creat_time') return render_template('base.html',questions=ques)
