Data from DB to chart for many web clients

zova · 30 January 2024 21:28

I display data from DB on dashboard. There are chart nodes and some navigation buttons nodes (backward, forward, zoom in, zoom out). Everything works enough good until one more user looks into that dashboard.
My question is: how to do individual acting navigation buttons and data from DB for each web clients.

Hi,
Maybe you can use ui-control to get the users IP, and only allow the socketID linked to that IP to use controls until disconnect or timeout. Or a button to lock control to socketID , and a button to ask for control, with a timeout to take control if no response from user in control.

Or try the new Dashboard 2, which i believe allows multiple users.

Colin · 31 January 2024 10:17

I don't think that feature is implemented yet.

zova · 31 January 2024 19:27

I think use socketID is good idea. Output of Chart node has a socketID, so there isn't need use ui-control.
I'll do-over my flow and share results here. Many thanks!

I solved issue of chart multi user. My beginners flow is as follow:

I celebrated too soon!
My test system had only "template" node. Than node works socketid sensitive way. But nodes "date picker" and "chart" it seems so work not socketid sensitive way.
Could somebody be so kind to make nodes "date picker" and "chart" socketid sensitive.
Help!
