- 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）
- 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/‘)
