I want a better way to update images on a webpage instead of forcing the webpage to refresh every 60 seconds.
I wrote a little status page that monitors some of our web sites. It uses web.py and displays a list of servers I have inputted into a database.
Each server that is up gets a Green png image displayed next to it.
When a server goes down I update the status in a local mysql database to false.
The next time the page refreshes it gets a red png displayed next to it.
Right now that red png file does not display until I refresh the page.
Is there a way in web.py (python) that I can make just that image dynamic without having to refresh the whole page? Or do I have to use something else to make it work?
Well, the generic answer is that you use AJAX and put a script on each server that will return "up" or something every time your page checks.
Here's a tutorial on how to do AJAX with web.py specifically: http://kooneiform.wordpress.com/2010/02/28/python-and-ajax-for-beginners-with-webpy-and-jquery/
