Flask-异步渲染模板 [英] Flask - render template asynchronously

问题描述

我正在制作一个Flask应用程序，我想知道是否可以为路由渲染一个模板，但是在功能完成后重定向用户.当前使用的是Python 2.7，这是我的示例

I'm making a Flask app and I was wondering if I could render a template for a route, but redirect the user after a function is complete. Currently using Python 2.7 Here is my example

@app.route('/loading/matched')
def match():
    time_match()
    return render_template('matched.html')

def time_match():
    # match two users based on time
    sleep(3) # pretend to be doing
    return redirect('/loading/generation')

我不知道从哪里开始.我应该使用图书馆吗?

I don't know where to begin. Is there a library I should use?

推荐答案

在我看来，这听起来像是客户端的事情?您是否想要类似加载栏的东西?

This sounds more like a client sided thing to me? Do you want something like a loading bar?

您可以提供一个ajax路由，该路由会在服务器端启动繁重的工作量-而客户端确实显示出一定的进度.工作负载完成后，您将呈现一个模板，然后再通过ajax加载该模板.

You could provide an ajax route which initiates heavy workload on the server side - while the client does show some progress. Once the workload finished you render a template which than gets loaded via ajax.

对于asycn工作负载，您可以查看 Celery ，这是一个很棒的库.它甚至可以在单独的服务器上工作...

For asycn workload you could look into Celery, which is a great library for that. It even can do work on a seperate server...
