Show calendar based on IP Address accessed

I made the change and it first showed correctly, but when I refresh any one of the client, the other client is getting both the calendars. What is wrong? Here is my updated calendar.js as suggested by you.

Please let me know if I have to do something about this.

@Spinster sorry, explain
the other client

on refresh, everything is the same in the module.

each module has a unique id assigned, based on its placement in config.js
calendar sends its id down to its helper
and the helper sends the id back on response. as the response mechanism is a broadcast to all connected clients.
the clients then check to see if this response is for their request.
from code posted

also, please start using code block wrapper for all config, code and error postings

select that pasted text

@sdetweil

Sorry for not explaining it clearly.
I have two clients, one from a browser using http://ip:8080 and another the native client.

upon using pm2 start MagicMirror, I get the out put in native client and the browser properly showing their respective calendar.

If I hit refresh button on browser, browser is showing only its own calendar however the native client is displaying both the calendars (ie. its own and the one which is supposed to be shown in browser), If I hit Ctr-R on the native client, then browser is showing both the calendars while the native client is showing only its own calendar.

Also I don’t understand the following instructions, please explain what should I do

also, please start using code block wrapper for all config, code and error postings

@Spinster said in Show calendar based on IP Address accessed:

don’t understand the following instructions, please explain what should I do

when creating a message here on the forum, if you are inserting code, config, or error text (like you did when u pasted the whole calendar.js, or the part of the module config)

do the instructions I gave

sdetweil · May 8, 2024, 1:25 PM

@Spinster I rejected your post (AND a second time) . I already fixed the prior
AND you left your unique info in the module info…

anyhow…

found the issue… the ‘identifier’ is based on placement in config.js SO, it will be the SAME on both browsers… oops…

here are the two lines to fix

in the socketNotificationReceived function
change this

		if (this.identifier !== payload.id) {
			return;
		}

to this

		if (this.identifier+(this.ourIPAddress?'_'+this.ourIPAddress:'') !== payload.id) {
			return;
		}

and 2.
in the addCalendar routine
change this

		id: this.identifier,

to this

		id: this.identifier+(this.ourIPAddress?'_'+this.ourIPAddress:''),

@sdetweil

You did it! Excellent, I really appreciate your versatility and quick response.

Hope this shall become a feature for the calendar or any other modules if anyone has similar requirement and prefers it.

Sincere Thanks to you and gratitude for your effort and time~

sdetweil · May 8, 2024, 1:43 PM

@Spinster I don’t know if this will become a feature… but at least you know how to add it for your environment
if it was a feature, I would recommend adding the getip rest api call to the base MM code.

I updated the prior code changes to include these latest , so its all in one place

it was a fun, thought provoking, exercise.

sdetweil · May 8, 2024, 5:28 PM

@Spinster another conversation highlighted another change required
and a bug

I’ll update my code here later

oh, and to help you, you could fork the MagicMirror repo
and use it, adding this code,
and saving to the repo, so next update
you can sync the fork and git pull to your system

sorry my new phone and thumb don’t agree where the keys are… lol and correction never gets it right

Spinster · May 8, 2024, 5:24 PM

@sdetweil

I can’t thank you much for your sincerity in making it correct. Looking forward to the updated code.
I will try to contribute too in future like you.
Thank you once again.

@Spinster

SO, the ‘bug’ is that this notification , added in pull request 2881 in
https://github.com/MagicMirrorOrg/MagicMirror/pull/2881
in August 2022
edit: I just opened issue 3443 for this problem
https://github.com/MagicMirrorOrg/MagicMirror/issues/3443

	socketNotificationReceived (notification, payload) {
		if (notification === "FETCH_CALENDAR") {
			this.sendSocketNotification(notification, { url: payload.url, id: this.identifier });
		}

added the code in the WRONG place… socketNotificationReceived is ONLY triggered by the node_helper sendSocketNotification,
NOT by other modules doing sendNotification
NO OTHER module can force a sendSocketNotification from our helper

THAT is notificationReceived… (which we JUST added for the 1st time… oops)

So,
remove this

		if (notification === "FETCH_CALENDAR") {
			this.sendSocketNotification(notification, { url: payload.url, id: this.identifier });
		}

and move it to the notificationReceived() function

@sdetweil said in Show calendar based on IP Address accessed:

   notificationReceived(notification,payload){
 	if(notification === 'ALL_MODULES_STARTED'){
        }  else  if (notification === "FETCH_CALENDAR") {
        	this.sendSocketNotification(notification, { url: payload.url, id: this.identifier });
        }

and THEN we need to change the this.identifier to account for the ip based ID, so if some OTHER module
asks THIS calendar instance to refresh ITS data, it asks for the correct content

      else  if (notification === "FETCH_CALENDAR") {
        	this.sendSocketNotification(notification, { url: payload.url, id: this.identifier+(this.ourIPAddress?'_'+this.ourIPAddress:'') });
        }

I’ll add this to the other code, done … I’ll leave the explanation here
