Django可以做多线程工作吗？ [英] Can Django do multi-thread works?

问题描述

我有一个问题，Django可以做多线程工作吗？

这是我要做的：点击网页上的一个按钮，然后在models.py中启动运行一些功能，例如抓取一些数据从互联网，完成后，它返回给用户的结果。

我想知道我必须打开一个新的线程来执行model.py中的函数，有人可以告诉我怎么做吗？非常感谢。

解决方案

1. 是的，它可以多线程，但一般来说，做等同的您可以阅读关于芹菜-django教程的内容。 / a>


2. 您很难想要强制用户等待网站。

以下是您正在描述的示例。

 用户发送请求
 Django receive =>产生一个线程来做别的事情。 
主线程完成&&其他线程完成
 ...（之后完成两个任务）
响应作为一个包发送给用户。 
  

更好的方法：

 用户发送请求
 Django receive =>让芹菜知道嘿！这样做！ 
主线程完成
响应发送给用户
 ...（稍后）
用户收到交易余额
  

I have a question, that can Django do multi-thread works?

Here is what I want to do: click a button on a web page, then there are some functions in model.py starts to run, for example, crawl some data from internet, when finished, it returns to user the results.

I wonder that I have to open a new thread to execute the functions in model.py, can anybody tell me how to do it? Thank you very much.

解决方案

1. Yes it can multi-thread, but generally one uses Celery to do the equivalent. You can read about how in the celery-django tutorial.
2. It is rare that you actually want to force the user to wait for the website. While it's better than risks a timeout.

Here's an example of what you're describing.

User sends request
Django receives => spawns a thread to do something else.
main thread finishes && other thread finishes 
... (later upon completion of both tasks)
response is sent to user as a package.

Better way:

User sends request
Django receives => lets Celery know "hey! do this!"
main thread finishes
response is sent to user
...(later)
user receives balance of transaction
