实现搜索功能

1.准备视图函数search()

1 # 模糊查找
2 @app.route(‘/search‘, methods=[‘GET‘, ‘POST‘])
3 def search():
4     qu = request.args.get(‘q‘)

2.修改base.html 中搜索输入框所在的

1 <form class="navbar-form navbar-left" role="search" action="{{ url_for(‘search‘) }}" method="get">
2                         <div class="form-group">
3                             <input type="text" class="form-control" placeholder="搜索" required name="q">
4                         </div>
5                         <button type="submit" class="btn btn-default">搜索</button>
6                     </form>

3.完成视图函数search()

 1 # 模糊查找
 2 @app.route(‘/search‘, methods=[‘GET‘, ‘POST‘])
 3 def search():
 4     qu = request.args.get(‘q‘)
 5     query = Question.query.filter(
 6         or_(
 7             Question.title.contains(qu),
 8             Question.detail.contains(qu),
 9         )
10      ).order_by(‘-creat_time‘).all()
11     context = {
12         ‘user‘: ‘huadahua‘,
13         ‘title‘: ‘大家好”‘,
14         ‘time‘: ‘2017-09-29‘,
15         ‘detail‘: ‘这是我的python‘,
16         ‘questions‘: query
17     }
18     return render_template(‘index.html‘, **context)

search结果：
