- 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_
@app.route('/search/')
def search():
qu = request.args.get('q')
pos = Post.query.filter(
or_(
Post.title.contains(qu),
Post.detail.contains(qu)
)
).order_by('-creat_time')
return render_template('jianshu.html', post=pos)
<form action="{{ url_for('search') }}" method="get" class="navbar-form navbar-left">
<input name="q" type="text" class="form-control" placeholder="请输入关键字">
<button type="submit">搜索</button>
</form>
