Show calendar based on IP Address accessed

Still I can’t catch you.

[2024-05-07 15:03:33.741] [LOG]   Use existing calendarfetcher for url: https://ics.calendarlabs.com/76/mm3137/US_Holidays.ics

The log shows, duplicated URL would be integrated into existing fetcher, So unlike your words, 3 clients doesn’t make 3 duplicated wasted fetcher.

If clientA needs cal1, cal2, cal3 and clientB needs cal1, cal4, cal5. In this case server should fetch 5 calendars anyway. User may need cal1 ~ cal5 even on 1 screen or 2 screens, ther server’s burden would be the same.

The only aspect that could be considered a waste is the transmission of unusing event data for cal4 and cal5 to clientA, but unless it’s a performance issue with the data parsing algorithm, simply having large data size being transmitted isn’t particularly problematic. Moreover, since the data is dropped in my code as soon as the notification is received, it can’t be deemed a significant memory issue. If the data size itself becomes problematic, it implies there’s already a problem with the original calendar module using cal1, cal2, cal3, cal4, and cal5.

Too skeptic.

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

Modified the calendars to suite mine. I could see even if there is no calendar defined for a particular ip. Please advice

in the calendar config, I added clientMap.

{
	module: "calendar",
	header: "US Holidays",
	position: "top_left",
	config: {
		clientMap: {
			"192.168.178.63": [ "cal1", "cal2", "cal3" ],
			"192.168.178.22": [ "cal3", "cal4", "cal5" ]
		},
		calendars: [
			{
				url: "...",
				name: "cal1",
			},

...

[sdetweil]

@Spinster yes, the two pieces together

ipaddress:“…”
at each cal url block… only does one ipaddress per url

[Spinster]

@MMRIZE
Here is my config

	{
		module: "alert",
	},

	/*
	{
		module: "updatenotification",
		position: "top_bar"
	},*/
	{
		module: "clock",
		position: "top_left"
	},
	{
		module: "MMM-ModuleMonkeyPatch",
		config: {
			patches: [
				{
					module: "calendar",
					method: "socketNotificationReceived",
					patch: async function (original, args) {
						const [ notification, payload ] = args
						if (notification === "CALENDAR_EVENTS") {
							const calendarName = this.config.calendars.find((cal) => cal.url === payload?.url)?.name
							const r = await fetch('http://10.5.11.1:8080/modules/getip')
							const ip = JSON.parse(await r.text())?.[ 'address' ] ?? null
							console.log(ip)
							if (!this.config.clientMap?.[ ip ]?.includes(calendarName)) {
								return original(notification, { ...payload, events: [] })
							}
						}
						return original(notification, payload)
					}
				}
			]
		}
	},
	{
		module: "getip",
	},
	{
		module: "calendar",
		header: "Home Cal",
		position: "top_left",
		config: {
			clientMap: {
				"10.5.11.5": [ "cal1" ],
				"10.5.11.6": ["cal2"]
			},
			calendars: [
				{
					fetchInterval: 10 * 60 * 1000,
					symbol: "calendar-check",
					url: "https://homecals/xEzboFt7Kr3Yfiys?export",
					name: "cal1",

				}
			]
		}
	}

This is showing both 10.5.11.5 and 10.5.11.6 the same calendar. Though 10.5.11.6 should not have any calendar since it is not defined. Even I tried without an entry of 10.5.11.6 in calendar map but it still showing the calendar. What am I doing wrong. Please advice

[Spinster]

@MMRIZE I even added the calendarmap, I hope you seen my config.js sent earlier

Sorry, i think I have not installed Monkey module, will install and check again

[Spinster]

@sdetweil

Should I use your earlier code and this? Please advise

[sdetweil]

@Spinster yes you need both

I am away from my system for another couple hours

will collapse to one post then

[sdetweil]

@Spinster ok, here is the final

in calendar.js

add these variables

		updateOnFetch: true,
		useIPAddress: false     // add config var
	},
	timerHandle:null,                 // add this
	ourIPAddress:null,              // add this 
	requiresVersion: "2.1.0",

change this

	// Override start method.
	start () {

to
this

	// Override start method.
	startup () {

add this code

			let ip_match = false;
			if(this.config.useIPAddress){
			 const client_ip_for_this_calendar = this.getCalendarProperty(calendar.url, "ipaddress", null)
			 if(this.ourIPAddress)
			 	  ip_match = client_ip_for_this_calendar.includes(this.ourIPAddress)
			}
			if(this.config.useIPAddress == false || ip_match==true)
			  this.addCalendar(calendar.url, calendar.auth, calendarConfig);   // old original   line 

and add this routine somewhere

  notificationReceived(notification,payload){
  	if(notification === 'ALL_MODULES_STARTED'){
  		// if we are using ip address checking
  		if(this.config.useIPAddress){
  			// loop thru all the modules
  			let m = MM.getModules().withClass("getip");
  			if(m.length){
  				// if getip is configured and not disabled
  				if((m[0].disabled== undefined || (m[0].disabled != undefined && m[0].disabled == false)) ){
  					// start a timer to wait for getip to finish
  					this.timerHandle = setInterval(()=>{
  						// get its dom content
  						let client_ip = document.getElementById("getip_address")
  						// if we found id
  						if(client_ip !== null){
  							// stop the timer
  							clearInterval(this.timerHandle)
  							// save our IP address, only need to look it up once
  							this.ourIPAddress=client_ip.innerText
  							// call startup
  							this.startup()
  						}
  					}, 500)
  				}
  			}
  			// thru the loop, didn't start a timer, module not found
			  if(this.timerHandle === null){
					// didn't find getip
					// module not found, can't do this later either
					this.config.useIPAddress = false;
					this.startup()
				}
			}
  		// use default
  		else
  			this.startup()
  	} 
  	else if (notification === "FETCH_CALENDAR") {
			this.sendSocketNotification(notification, { url: payload.url, id: this.identifier+(this.ourIPAddress?'_'+this.ourIPAddress:'') });
		}
  },

and in the socketNotificationReceived routine
change this

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

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

to this

	socketNotificationReceived (notification, payload) {

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

and in the addCalendar routine
change this

		id: this.identifier,

to this

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

to use

add the getip module to config.js, anywhere
add property to calendar above the calendars list (but still inside the config:{}{ section)

useIPAddress:true,

in any cal url block you want to be sensitive to IP address add property

    ipaddress:"xxx yyy zzz",  // space separated list of client ipaddresses this calendar can be displayed on

andhow

After installing MonkeyPatch and adding the patch you have mentioned, I get the following error message when I run , npm run config:check
[2024-05-07 23:32:55.179] [INFO] Checking file… /home/vjkings/MagicMirror/config/config.js

}

If I ignore the error and run the server, I don’t get any calendar and it just says Loading… in the mirror page
What is the reason for the error. Please advice

[Spinster]

@sdetweil

Wow, Clear, will try it and provide feedback please.

[Spinster]

@sdetweil

Hi,
I made all the changes you have mentioned, it is working!!!. Thank you so much for the efforts.
However, following are the observation,
When I add the config.js with useIPAddress: true (calendar.js has the entry of useIPAddress:false in its default), there is no effect, however in calendar.js if I set the useIPAddress: true, it is working, I don’t understand why the configuration settings are not taken.

I clearly added the useIPAddress: true before the calendars declared as part of the module configuration. Please advice how to fix this.

I also have doubt on when we override the start to startup, how the notificationreceived is called. What happens when there is no start in the module.

In fact this is the first time, I have added code without understanding of anything :).

Please help me with configuration settings (config.js) to get it effected than hardcoding it to calendar.js

[sdetweil]

@Spinster can you show the calendar config, you can leave out the calendars:[] list entries

start is optional. but only called once
getip has not placed its content yet.

the notification ALL_MODULES_STARTED is sent be the system when all the
modules start methods have been called

from the module development doc

[Spinster]

@sdetweil
Thank you for the details.

As required, my calendar config as follows

	{
		module: "getip",
		position:"bottom_left"
	},
	{
		module: "calendar",
		useIPAddress: true,
		header: "My Calendars",
		position: "top_left",
		config: {
			calendars: [
				{
					name: "cal01",
					fetchInterval: 5 * 60 * 1000,
					symbol: "calendar-check",
					url: "https://mycalendar/xEzboFt7Kr3Yfiys?export",
					ipaddress: "10.5.18.252 127.0.0.1 10.5.14.104",

				},
				{
					name: "cal02",
					fetchInterval: 10 * 60 * 1000,
					//useIPAddress: true,
					symbol: "calendar-check",
					url: "https://mycalendar/4aK7xZPQkGKz6nCZ?export",
					ipaddress: "10.5.11.5",

				}
			]
		}
	},

Please let me know if I have done any mistake

[sdetweil]

@Spinster yes, it has to be inside the
config:{} section

everything outside config are MagicMirror properties about a module
see
https://docs.magicmirror.builders/modules/configuration.html#example

config is properties FOR the module and override what is defined in the module defaults:{} object

[Spinster]

@sdetweil

[sdetweil]

@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

paste text into the message editor
empty line above and below
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]

@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

1. 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:''),
