实时网站的python框架

[英]python frameworks for a real time website

原文 2013-04-30 08:01:54 3 1 python/ django/ plot/ twisted/ tornado

I'm trying to learn web programming in python, and have the following project in mind: mine the yahoo finance api for instrument data, and display it in real time, as well as plot charts based on instrument data. 我正在尝试使用python学习Web编程，并且考虑到以下项目：挖掘Yahoo Finance API的工具数据，并实时显示它，以及基于工具数据的图表。

I already did something similar using wxpython, and I'm interested in how I would accomplish this in a web application. 我已经使用wxpython做过类似的事情，并且我对如何在Web应用程序中完成此过程很感兴趣。

My first thought was to use django and matplotlib on the server, and have the client request updated chart images through jquery at a certain time interval, but after a bit of research I came upon libraries like twisted and tornado...and now I'm confused. 我的第一个想法是在服务器上使用django和matplotlib，并让客户端在一定的时间间隔内通过jquery请求更新图表图像，但是经过一番研究，我发现了Twisted和Tornado之类的库……现在我我很困惑。 Would they work better for this web app than django ? 他们会比django在此Web应用程序上更好地工作吗？

After the above rambling, my question is: what library should I use for writing the web app i have in mind ? 经过上述讨论之后，我的问题是：我应该使用哪个库来编写Web应用程序？ I'm also thinking that I should abandon matplotlib, and generate the chart on client side, but I'm not sure what javascript library would allow me to do that, if any. 我还认为我应该放弃matplotlib，并在客户端生成图表，但是我不确定哪个javascript库可以允许我执行此操作（如果有）。

Few tips: 一些提示：

1/ Do not plot your data at backend . 1 /不要在后端绘制数据。 Instead use the browsers to generate charts.I would recommend using jqplot , or highcharts . 而是使用浏览器生成图表。我建议使用jqplot或highcharts 。

2/ Yes, you can use tornado or twisted instead of django, as they are asynchronous servers, and would provide faster handling of requests. 2 /是的，您可以使用龙卷风或twisted而不是django，因为它们是异步服务器，并且可以更快地处理请求。

3/ You should create a REST interface of your application, with server side only sending JSON data, and do all the UI templating and charting on client side. 3 /您应该创建应用程序的REST接口，服务器端仅发送JSON数据，并在客户端进行所有UI模板化和图表化。

4/ Backbone.js (recommended, but you can use some other MVC framework), would also prove to be helpful if your app grows too complex. 4 / Backbone.js （推荐，但您可以使用其他MVC框架），如果您的应用程序变得过于复杂，也会证明是有帮助的。
