Django won't refresh staticfiles

• Clearing static file python manage.py collectstatic --noinput --clear. This will clear the statics beforehand.

• Clear the browser cache

• Add a random string after the js file include, e.g jquery.js?rand=23423423, with each load.

Did it help?

It sounds like both your browsers have the javascript file cached. In Chrome you can clear the cache by pressing Ctrl + Shift + Del and ticking just 'Cached images and files'. Firefox probably has a similar shortcut.

You can take a look at this question on tips to disable caching of static files on your development server altogether.

You need to bust the browser cache. This template tag will output a time based uuid when DEBUG=True. Otherwise it will look for a PROJECT_VERSION environment variable. If that is not found it will output a static version number.

from django import template                                                                                                              
from django.conf import settings                                                                                                         

register = template.Library()                                                                                                            

@register.simple_tag(name='cache_bust')                                                                                                  
def cache_bust():                                                                                                                        

    if settings.DEBUG:                                                                                                                   
        version = uuid.uuid1()                                                                                                           
    else:                                                                                                                                
        version = os.environ.get('PROJECT_VERSION')                                                                                       
        if version is None:                                                                                                              
            version = '1'                                                                                                                

    return '__v__={version}'.format(version=version)

You would use in a template like this:

{% load cache_bust %}

<link rel="stylesheet" href="{% static "css/project.css" %}?{% cache_bust %}"/>

and here is the resulting output:

<link rel="stylesheet" href="/static/css/project.css?__v__=7d88de4e-7258-11e7-95a7-0242ac130005"/>
