[Django]-How to auto refresh admin page on browser after data have changed on server?

You can send ajax request (do it in your custom js file) to same url == window.location.href (for example every 10 seconds)

class OrderAdmin(admin.ModelAdmin):
    class Meta:
        model = Order
    class Media:
        js = ("my_code.js",)
