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.

Reset to default 7

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:

https://bitbucket/ad3w/django-sstatic/src/4401a4bc3058618dfc2eafaee6a23d287a99ede5/sstatic/templatetags/sstatic.py?at=default

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.

  1. Manually refresh the page

Using Windows OS with browsers Google Chrome or IE9, hit (CTRL + F5)

  1. Refresh the page at certain time intervals (in this example, browser refreshes every 3 seconds) <head>

    <meta http-equiv="refresh" content="3" >

    </head>

  2. Refresh the page when a user clicks a button

    <form>

    <INPUT TYPE="button" onClick="history.go(0)" VALUE="Refresh">

    </form>
