How to solve django server restart issue?

when one superuser makes changes in the user in the admin section,like activating a deactivated user then in the user page active users should be reflected instantly
In my case, I created a multiple selection dropdowns where I can select users, in the dropdown recently changed users are not reflecting until I manually restart the server to see the changes but I need it without restarting the server it should reflect instantly in the custom users page. How can I solve it?

What do you mean “instantly”?

It should be reflected when the page is refreshed.

When you say “admin section”, are you talking about the Django Admin or some page that you have created?

Where did you create this? How? What is the code behind this?

What “custom users page”? Please show the code for this.
