Reload (fetch from db) upon hitting back button

It is the browser. You will have to resort to some javascript wizardry to force the fetch.

Hmm, actually another way around it would be LiveView, wouldn’t it? Even the cached page would establish soviet connection and start receiving changes in real time, right?

You likely are better off using LiveView for your project as we chatted a little while ago anyway, so yep.

Lol wtf autocorrect Yes, I guess LV is making sense for more and more pieces here.

Yes. The javascript wizardry I was referring to is simply:

window.addEventListener("popstate", function(e) 
{   location.reload();
});

You are correct, if you are using LV and are jumping between views using live_redirect there’s no need for any additional JavaScript. When you hit the browser’s back button your LV will perform a stateful mount and call mount and handle_params. Where did you place the logic that fetches data from the DB? As long as it’s triggered from these 2 callbacks, you should be fine. Maybe put some debug code in mount and handle_params to convince yourself that they are being called.
