Django static files are not updated
Question
In my Django project the application my_app has a template which references a javascript static file:
<script src="{% static 'my_app/my_script.js' %}"></script>
Once I installed my_script.js in my_app/templates/my_app, everything seemed to work. At some point I overwrote my_script.js with a different script, such that my_script.js has a different content now.
However, when I load my_app with my browser, it loads the old my_script.js, although it does not exist anymore. How can I resolve it? Thanks.

I often use ?v=00001 or any define number to force clear cache in browser. So in your case it could be:
<script src="{% static 'my_app/my_script.js?v=00001' %}"></script>
Or:
<script src="{% static 'my_app/my_script.js' %}?v=00001"></script>
Next time you change the script, increase the number to 00002. Of course there are many ways to do this but I still prefer this method.

You can add a cache-busting ?get=parameter. I like to define a {% statichash %} template tag that reads the file and appends a hash of the file contents as a get param. This is similar, uses the file's modified time instead of hash, but same idea:

I fixed it by including writing code to refresh the browser. This way, it will always get the latest updated static files instead of reading from its cache.
There's 3 way to do this.
- Manually refresh the page
Using Windows OS with browsers Google Chrome or IE9, hit (CTRL + F5)
Refresh the page at certain time intervals (in this example, browser refreshes every 3 seconds)
<head><meta http-equiv="refresh" content="3" ></head>Refresh the page when a user clicks a button
<form><INPUT TYPE="button" onClick="history.go(0)" VALUE="Refresh"></form>
